Main Products in Clean Air Zisun holds multiple core filter materials and filter technologies including high performance glass fiber filter media, low-resistance melt-blown filter, high-efficiency PTFE membranes, micro electrostatic filter media, nano-filter materials (under development) and chemical filter materials and other filter materials and equipment. 19 / 191 Zisun Annual Report of 2021 Taking different regions, different scenarios, different industry characteristics into consideration, Zisun provides customized products for users. There is a fully consideration of temperature, humidity, space, region, environment, function and other factors on air quality. The goal is to satisfy user’s pursuit of dust-free, sterile, and healthy environment and solve the current problems of high energy consumption, difficult maintenance, hardness of maintenance and loud noise. As one of the few worldwide with the supply capacity of high-performance glass fiber media, low-resistance melt-blown filter media, high-efficiency PTFE membranes, micro electrostatic filter and chemical filter materials, our “Clean Air” materials cover international standard filtration efficiency (such as EN779, EN1822 and ASHRAE/HEPA/ULPA) with the MPPS efficiency of 99.999999% and above. * The filtration efficiency of air filter material varies with dust particle size. At a certain particle size point, the efficiency is the lowest, that is, the penetration rate is the largest, which is called the most easily penetrable particle size (MPPS). MPPS varies with filter material and air speed. For HEPA and ULPA air filter materials, MPPS is generally between 0.1-0.25μm. 20 / 191 Zisun Annual Report of 2021 Name Advantage Usage made of ultra-fine glass fiber, fiber distribution is uniform, high filtration Used in high-end manufacturing Micro precision, large dust holding such as semiconductor, medicine, Glassfiber capacity, good physical strength, biology, also in areas that require Filter Media good machinability, heat resistance, the Solution of fine particles of flame retardant, covering 0.3um and below ASHRAE/HEPA/ULPA grades made of polypropylene, the fiber diameter of 1-5um, with a unique capillary structure, electrostatic Used in air purifiers, fresh air Melt-blown electreted, the filtration efficiency of systems, personal protection and Filter Media HEPA level, with excellent other fields performance of both of filtration and physical strength Used in fields with high filtration Made of nano-fineness PTFE fiber, efficiency and low system High- very high porosity, resistance requirements, such as CLEAN AIR efficiency combination of ultra-low resistance electronics, semiconductors, etc., PTFE and ultra-high efficiency, and also in fields with waterproof Membrance Waterproof and breathable, long life, and impact resistance chemically stable requirements, such as vacuum cleaners, etc. Used in indoor air treatment, dealing with polluting particles, Micro High capture efficiency, zero efficiently removing air VOCs, Electrostatic consumables, reusable cleaning, long quickly and effectively killing Filter life, low wind resistance, low noise, pathogenic microorganisms in the Material and more energy saving air, eliminating peculiar smell in the air, and improving air freshness Fiber diameter of 0.3-0.5um, could Used in automobile cabin, engine be used in combination with wood intake, gas turbine and high-end Nanofiber pulp fiber, synthetic fiber and other manufacturing where there is a Filter Media materials, with good durability, need for particulate matter physical strength, temperature management resistance and dust holding capacity High-performance glass fiber filter media, low-resistance melt-blown filter material, and high-efficiency PTFE membrane are produced by each patented technology. Based on the connection and combination of superfine fibers of different diameters, those air filter materials, which can be observed with distinct morphologies under SEM, hold different filtration properties During the production process, Zisun needs to control the raw material technology 21 / 191 Zisun Annual Report of 2021 and stabilize large-scale production at the nanoscale. The comprehensive technology is extremely high. 1.1 Glass Fiber Filter Paper Fine micro glass fiber is the main raw material of glass fiber filter media which is produce by Wet-laid process. Usually, the thickness of this glass fiber filter media is 0.3mm. Compared with other filter materials made of animal and plant fibers, synthetic fibers and activated carbon, it has the characteristics of large dust holding capacity, high filtration efficiency and uniform fiber distribution. As an ideal clean air filter material, it is a core component of clean air equipment. Glass fiber filter media is widely used in advanced manufacturing, biomedicine, animal husbandry and other fields that require high air cleanliness. (Fig of Glass Fiber Filter Media Product) (High-performance glass fiber filter media,Zoom in 488 times) 1.2 High-efficiency PTFE Membrane 22 / 191 Zisun Annual Report of 2021 PTFE is the abbreviation of polytetrafluoro ethylene. It has a molecular weight, which is generally millions, either hundreds of thousands to the lowest or more than ten million to the highest. The global industry continues to explore and develop new filter materials in recent years. PTFE membrane has attracted widespread attention in the industry for its unique molecular structure and superior filtration performance. Bulking and stretching the PTFE molecule in two directions, here come a high-efficiency PTFE membrane containing a large number of micropores and high porosity. It combines the advantages of more stable chemical properties, more uniform fiber distribution, higher filtration performance, and lower resistance and become an irreplaceable new high-end filter material in some special application fields. After several years of R&D, Zisun owning unique technical advantages, is one of the few companies in the world that can stably produce high-performance PTFE membranes in large quantities. Due to ultra-high efficiency and ultra-low resistance, PTFE Filters shows low system resistance, low energy consumption and stable chemical properties which are widely used in panels, semiconductors, medicine, household appliances and other industries. It can also be matched with other filter materials and equipment to provide optimal "Clean Air" solutions for different scenarios 1.3 Low-resistance Melt-blown Media Low-resistance melt-blown media is produced by melt-blown method, in which polymer electret masterbatches such as polypropylene are blown through the polymer melt at high temperature and high speed, so that the fibers are rapidly stretched, and the fibers are then cured on the curtain device to form melt-blown filter media. The filtration performance is influenced by the fineness of fiber diameter and electrostatic adsorption effect. The low-resistance melt-blown media has a unique capillary structure and the filtration efficiency can reach HEPA level, which can be used in air purifiers, fresh air systems, individual protection and other fields. 23 / 191 Zisun Annual Report of 2021 1.4 Micro Electrostatic Filtration Media Micro electrostatic filtration media uses a strong electric field with a unique dielectric material as the carrier to sterilize and adsorb fine particles (blocking aerosols) to achieve air disinfection and purification technology. The dust collection module is made of non-metallic materials (polymer) and graphene materials as carriers, and is combined with driving circuits, which overcomes the disadvantages of traditional metal electrostatic generation of ozone, lightens arc discharge, with powerful function of efficient sterilization, adsorption of particles as small as 0.01um. 1.5 Chemical Filtration Media Chemical filtration media is used for the treatment of nano-scale molecular compound gases such as VOCs, AICD, BASE, etc., and extremely low concentrations of airborne molecular pollutants at the ppb level one billionth concentration) or even ppt level (one trillionth concentration). Zisun has made a breakthrough in the bottleneck of airborne molecular pollutant control technology through in-depth principle research and application practice. We provided chemical filtration equipment for Hefei Jinghe Semiconductor Phase II project in the semiconductor field, Nanjing China Electronics Panda Lighting, KinWong Electronics and CSCEC Electronics in the panel field, Nine Dragons Paper, Jinhai Pulp & Paper and other paper companies, as well as the Bank of China and China Settlement Center data room projects to provide chemical filtration equipment to ensure safe production in many industries. With the national policy’s emphasis on “high-quality development” and “high- quality life”, Zisun increasingly recognize that CLEAN AIR materials and technology play an important role in this area of improving the work efficiency of people and equipment, minimizing energy consumption, benefiting human health and environmental safety. Zisun has been cultivating the technology of clean air materials for many years, 24 / 191 Zisun Annual Report of 2021 actively excavating the properties of materials, and striving to expand new materials and new applications. 2. Technical Mechanism of Zisun Clean Air Materials The materials, equipment and solution of Zisun Clean Air portfolio is capable to protect human health, high-end manufacturing production processes, and the environment from the harm the air pollutants. Air pollutants components can be subdivided into particulate matter (PM) and airborne molecules (AM). As shown in the figure, different particulate pollutants in the air have different sizes, ranging from 0.1um to 500um. (Fig from Visual Capitalist) Common sources of particulate pollutants can be divided into four categories: Natural source: soil dust, pollen, spore, bacteria. Fixed Manmade source: fuel combustion (e.g., electricity generation, metallurgy, petroleum Industry, chemical industry, textile industry, heating supply, various industrial process, cooking etc.) Moved Manmade source: Exhaust gas emitted into the atmosphere 25 / 191 Zisun Annual Report of 2021 when various vehicles consume fossil fuel. Different production and living environments have different requirements for clean air. From high-end manufacturing to thousands of households, Zisun Clean Air materials have important applications scenarios. In the semiconductor field, for example, the production environment requires extremely high cleanliness, and the airborne particulate contaminants have a significant impact on the process yield, performance and reliability of products. A rule of thumb is that the particle size should be less than 1/10 times the size of the smallest feature on the device, i.e., a particle with a diameter of 0.03m will damage a feature with a line width of 0.3m. Therefore, controlling particulate contamination in the semiconductor manufacture process is of great significance to the economics of the production process. For the manufacturing process of panel field, the particles will adhere to the 26 / 191 Zisun Annual Report of 2021 surface of the substrate. In addition, the electrostatic attraction, Brownian motion, thermal motion, photosensitive phenomena, and colloidal micelle effects may cause particle adhesion. The rule of thumb is that the particle size must be less than half of the minimum device feature size, particles larger than this size can cause fatal defects, such as a 2 μm feature size cannot touch particles larger than 1 μm in size. For the public’s daily life related to indoor spaces such as homes, schools, offices, hospitals, etc., the state, industry, and the public are gradually emphasizing, paying attention, and popularizing the effects of airborne particulate pollutants on health. Airborne particulate matter can enter the human body through respiratory, digestion and skin, and has multiple negative impacts on human health. Respirable particulate matter (PM10) with an aerodynamic equivalent diameter of less than 10 μm can enter the upper and lower respiratory tract of the human body. PM2.5 and smaller diameter particles can enter the lungs and alveoli. PM0.1 can penetrate the body through the capillary membrane of the alveoli where the air is separated from the blood flow. In addition, fine particles may be enriched on heavy metals, acidic oxides, organic pollutants (such as polycyclic aromatic hydrocarbons, pesticides, etc.), and may also be carriers of bacteria and fungi, which are extremely harmful to humans. 27 / 191 Zisun Annual Report of 2021 (Fig from encyclopedie-environnement.org) Observed from the nano meter scale, Zisun high-performance glass fiber filter media, low-resistance melt-blown filter media, and high-efficiency PTFE membranes have unique filtration structures. According to the diffusion effect, interception effect, inertial effect, van der Waals force and Brownian motion, and sieve effect, our materials capture and intercept particulate pollutants in the air with various mechanisms. With a variety of patented technologies, Zisun can produce high performance fiberglass filter media, low resistance melt blown material and high efficiency PTFE membrane in a stable and large scale and make different clean air materials with high filtration efficiency with the help of connecting combinations of micron-level fibers of different diameters, which can filter with specific efficiency for various particles in the air. Zisun tests the performance of clean air filtration materials with 0.3um and 0.1um diameter test particles, and the highest efficiency can reach 99.999999%. There are common airborne molecular pollutants as follows: VOCs: e.g., Benzene, Toluene, Octane, Butyl Acetate, Ethylbenzene, Xylene and Nonane. Acid: e.g., Hydrogen Sulfide, Sulfur Dioxide, Nitrogen Dioxide, Nitric Oxide, Nitric Acid.

Vigorously promote the energy-saving renovation of existing buildings and municipal infrastructure in cities and towns and improve the energy-saving and low-carbon level of buildings. The “Proposal of the Central Committee of the Communist Party of China on Formulating the 14th Five-Year Plan for National Economic and Social Development and the Visionary Goals for 2035” has made “reaching a new level of people's well- being” one of the main goals of China's economic and social development in the 14th 46 / 191 Zisun Annual Report of 2021 Five-Year Plan period. To achieve this economic and social development goal, we must adhere to the people-centered development ideology, further address the most direct and realistic interests of the people, promote high-quality development, create a high- quality life, and continuously realize the people's aspirations for a better life. The China Central Committee and the State Council released the top-level policy of “1+N dual carbon” to help achieve “carbon neutrality and carbon peaking”. Local policies are frequently introduced one after another. The global requirements for green, environmental protection and energy saving are constantly improving, and various domestic and foreign demands have created more development opportunities for the fields of “clean air” and “high efficiency and energy saving”. (2) Introduction To the Clean Air Industry 1. Indoor Air Quality Economic development, the continued prevalence of the epidemic, and the public’s yearning for a better life have promoted the improvement of IAQ requirements. In the short term, there is an increasing demand for existing air conditioning systems and air quality improvement equipment and services(such as ventilators, Air Cleaning Products and Air Filters. In the long run, the demand for indoor air quality solutions continues to increase by focusing on providing users with value-added and high air quality solutions. 1.1 Relevant Policies According to the National Health Commission's "Indoor Air Quality Standards", (1) People spend more than 80% of their time indoors every day, the air they breathe mainly comes from indoors, and the chance and time of contact with indoor pollutants are more than outdoor. (2) The sources and types of indoor pollutants are increasing day by day, resulting in an even heavier level of indoor air pollution on the basis of outdoor air pollution 47 / 191 Zisun Annual Report of 2021 (3) In order to save energy, the degree of airtightness of modern buildings has increased. Due to the imperfect central air-conditioning ventilation facilities, indoor pollutants cannot be discharged outdoors in time, resulting in the deterioration of indoor air quality. WELL & Healthy Buildings Application Guide point out that the air, water, nutrition, light, health, comfort and spirit of buildings affect human health and well- being. Healthy Building Evaluation Standard (T/ASC 02-2016) require that the daily average concentration of indoor PM2.5 is not higher than 25ug/m3, the daily average concentration of PM10 is not higher than 25ug/m3, and the daily average concentration of CO2 is not more than 900ppm. According to the World Health Organization (WHO), nine out of ten people in the world breathe polluted air and seven million premature deaths each year are linked to air pollution which can be divided into 34% stroke; 26% ischemic heart disease; 22% chronic obstructive pulmonary disease; 12% acute lower respiratory tract infection in children; 6% lung cancer. 1.2 Industry Trends Modern humans, especially urban populations, spend the vast majority of their time indoors, and indoor air quality has a significant impact on the general public. According to the U.S. Environmental Protection Agency, indoor air quality is about five times worse than outdoor air quality. After the popularity of air conditioning systems in the 1970s, the sick building syndrome (SBS) emerged, which refers to adverse health or comfort reactions of people who spend varying amounts of time in buildings that are not caused by disease or a well-defined pathology. Studies have proven that sick building syndrome is mainly caused by severe indoor air pollution, high carbon dioxide concentration, poor lighting, and lack of thermal comfort. 48 / 191 Zisun Annual Report of 2021 In HVAC systems, air intakes often inhale dust particles, chemical contaminants, harmful viruses and bacteria, and other toxic particles which are captured by filters or lodged in ventilation ducts and other areas and may cause serious health risks. Then keeping ventilation systems in good clean and hygienic conditions can help prevent the build-up of harmful particles from spreading in the system. The fresh air system is also subdivided into various modes such as one-way flow, two-way flow and displacement ventilation. Displacement ventilation is a cutting-edge ventilation technology that enables high air quality, thermal comfort, and ventilation efficiency in residential areas, while also saving building energy consumption. 1.3 What Zisun Could Do with Indoor Air Quality At present, indoor air quality and comfort are generally solved by single or multiple systems such as HVAC unit, fresh air system and floor heating system. Our subsidiary Zisun Jinghua , together with Germany TROX, relying on our 20 years of rich experience in the field of clean air, has formed a professional team to create a comfortable and dust-free air conditioner for the high-end residential market. 49 / 191 Zisun Annual Report of 2021 Zisun Comfort Dust-free Air Conditioner for residential integrates fresh air purification, cooling and heating, dehumidification and humidification, variable air volume intelligent monitoring, and intelligent control into one system to provide users with a customized whole-house comfort system, combined with our rich “Clean Air” Materials, professional equipment and first-class technology, and strive to create a high- quality life for users that is energy-saving, dust-free, quiet, oxygen-rich, beautiful, and intelligent, and strive to seize the trend of consumption upgrades and the rapid development of the Internet of Things to promote the development of clean air, develop to the user end, provide services, identify the enterprise positioning and competitive advantages, and build a system integration ecology in the field of comfortable residential market. 50 / 191 Zisun Annual Report of 2021 2. New Energy Vehicles and Other Mobile Space Field As the epidemic continues to spread, the public is paying more and more attention to the safety of air quality in mobile spaces such as carriages, airplane cabins, and ship cabins. The structural design of new energy vehicles provides the conditions for them to be equipped with large-sized, high-efficiency cabin filters. With the gradual increase in the sales and ownership of new energy vehicles, the cabin filter element of new energy vehicles has ushered in a huge market prospect. 2.1 Related Policies In October 2021, the Central Committee of the Communist Party of China and the State Council issued the Opinions on Completely Accurately Implementing the New Development Concept and Doing a Good Job in Carbon Neutralization and the Carbon Peaking Action Plan before 2030. The plan clearly defines carbon reduction measures which calls for focusing on the implementation of green and low-carbon transformation of energy, energy conservation, carbon reduction and efficiency enhancement, carbon peaking action in the industrial sector, urban and rural construction carbon peaking action, transportation green and low-carbon action, circular economy boosting carbon reduction action, green low-carbon action Carbon technology innovation action, carbon sink capacity consolidation and improvement action, green and low-carbon national action, and orderly carbon peaking action in various regions, etc. The "New Energy Vehicle Industry Development Plan (2021-2035)" issued by the General Office of the State Council pointed out that my country's new energy vehicles have entered a new stage of accelerated development, and new energy vehicles have become the main direction of the transformation and development of the global automobile industry and a driving force for the continuous growth of the world economy. important engine. 51 / 191 Zisun Annual Report of 2021 The development of new energy vehicles by integrating various national policies is an important strategic measure to deal with climate change and promote green development. 2.2 Industrial Trends According to the report of the Passenger Vehicle Market Information Joint Conference, during the year of 2021, the cumulative sales of new energy vehicles nationwide will be 2.446 million with a cumulative year-on-year increase of 168.0%. By the end of 2021, the number of new energy vehicles in the country will reach 7.84 million, accounting for 2.60% of the total number of vehicles. Cars gradually change from a means of transportation to a consumer product with diverse functional needs. Automobile manufacture companies have moved to directly facing consumer demand. As the public pays more and more attention to high quality of life, car users have increasingly higher requirements for safety, comfort, health, and intelligence during driving. Therefore, healthy and intelligent new energy vehicles have become the development direction of many automobiles manufacturing companies around the world by investing a lot of resources in the research and development of "healthy cars". Due to its structural advantages, new energy vehicles provide conditions for assembling higher performance, larger size, faster and more efficient cabin filters. With the continuous increase in the demand for new energy vehicles, the demand for cabin filters is increasing day by day. Some leading new energy vehicle companies have proposed that they have developed “anti-biological and chemical weapons-grade” vehicles because air pollution will reduce the life expectancy of the public. This type of new energy vehicle is equipped with a variety of gas detectors and HEPA-level cabin filters, and the air purification effect of the car cabin is hundreds of times better than other. 52 / 191 Zisun Annual Report of 2021 New energy vehicles have two sets of electrical systems: high-voltage and low- voltage, and the valve-regulated lead-acid battery has to ensure the power supply of the low-voltage system of the vehicle and also wake up the high-voltage battery system.

And "the state promotes the purification of animal epidemics and encourages and supports units and individuals that raise animals to carry out purification of animal epidemics. 4.2 Industrial Trends The use of land in our country's animal husbandry is limited by the available natural resources, so the density of animal husbandry in my country is high, especially the density of pig breeding is alarming. High-density farming is accompanied by the pressure of environmental protection and disease protection. With the development of society and economy, people's consumption of animal food has changed, the requirements for quality are getting higher and higher, and the demand for categories is constantly diversified. Driven by a variety of policies, the large-scale and intensive trend of dairy cattle, pigs, and poultry farming has become more and more obvious, at the same time the accompanying disease control requirements have become more and more important. 59 / 191 Zisun Annual Report of 2021 (The interior of pig house overseas) Taking the pig farming industry as an example, China is the world's largest producer and consumer of pigs, and pork is the mainstream meat consumption variety in China. African swine fever is an infectious disease caused by African swine fever virus (ASFV) infecting domestic and wild boars which broke out in China for the first time on August 1, 2018. China's hog industry has encountered major epidemic prevention pressure. According to the data released by the National Bureau of Statistics, based on 2017 before the outbreak of African swine fever in China, China’s pork production fell by 10.85 million tons and 12.27 million tons in 2019 and 2020, respectively. The number of live pigs in 2019 and 2020 decreased by 144.42 million and 161.57 million, respectively. 4.3 Zisun in Animal Husbandry Since the large-scale outbreak of African swine fever in China, the pig breeding enterprises have raised the requirements for the prevention and control of the disease in pig houses. Zisun actively conducts technical communication with animal husbandry users, and specially developed a new filter material, which is a high-efficiency, low- resistance, high-temperature and high-humidity filter material with a filtration effect of over 94% for 0.3μm particles, for the special environment of high temperature and high 60 / 191 Zisun Annual Report of 2021 humidity in pig houses that require the fresh air of pig houses of outstanding breeding enterprises.

(3) High-efficiency Energy-saving Industry 1. The Field of Green Appliances Household appliances are the second largest source of residential energy consumption, accounting for more than 20% of total residential energy consumption (after heating), and up to 30% of residents' carbon emissions come from household appliances. Through the upgrading of the product structure of green household appliances, especially the promotion and popularization of low-energy consumption products in the market, the carbon emission of residents' consumption side can be effectively reduced. 68 / 191 Zisun Annual Report of 2021 The structure of the household appliance industry under the requirement of carbon neutrality is facing adjustment, and enterprises with high carbon emissions may be eliminated. 1.1 Related polices In June 2019, the “Green and Efficient Refrigeration Action Plan” jointly issued by the National Development and Reform Commission and other seven ministries and commissions put forward specific requirements for the municipal High efficiency and energy saving level of refrigeration products such as air conditioners in my country. In the policy documents such as the “Implementation Plan for Promoting the Update and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)” issued by the Ministry of Ecology and Environment and other departments, it is proposed to support the sales of green and smart home appliances and promote the upgrading of home appliances. The “Technology Roadmap for China's Household Refrigerator Industry (2019 Edition)” clearly proposes to achieve a comprehensive balance between energy saving and basic functions of refrigerators. By 2025, the High Efficiency and Energy Saving level of refrigerators will be increased by 25% compared with 2019, and by 25% in 2030 compared with 2025. 1.2 Industrial Trends Transmission is the major contributor (> 50%) to the total cooling load for typical domestic refrigerators. Understandably, insulation in refrigerator walls plays an important role in reducing it. Compared with traditional refrigerator insulation layer, vacuum insulation board board has lower thermal conductivity, longer insulation time and smaller thickness, with higher energy saving grade, and can enhance the effective utilization rate of refrigerator volume. With the continuous improvement of High efficiency and energy saving grade standards and environmental protection requirements for relevant household appliances 69 / 191 Zisun Annual Report of 2021 around the world, the traditional thermal insulation materials, especially for applications such as high-power and large-volume refrigerators, can no longer meet the requirements of high High efficiency and energy saving grade household appliances. (Figs of Vacuum Insulation Panel in Premium Refrigerator) At present, the VIP panels have been widely used in many premium refrigerator brands around the world and have become an important means of achieving High efficiency and energy saving upgrades for household appliances. 1.3 Zisun and Green Appliances Refrigerators are an important part of appliances, and since their introduction more than a hundred years ago, their related technologies and requirements have been constantly improving. As the core component of a refrigerator, its insulation layer is still mainly made of polyurethane. The excellent thermal insulation performance of VIP board has been gradually extended to water heater, rice cooker, kettle and other appliances that need thermal insulation and heat preservation. The high-efficiency inorganic vacuum insulation board produced by Zisun is the core insulation material of the VIP board. The core indicators such as thermal 70 / 191 Zisun Annual Report of 2021 resistance coefficient, physical properties and stability of the core material directly affect the vacuum degree, water absorption and thermal conductivity of the VIP board, and determine the comprehensive performance and service life of the VIP board. Zisun VIP core material owns the advantages of low thermal conductivity, thin thickness, small volume, light weight, fluorine-free manufacture process and easy recycling, etc., which could efficiently reduce the energy consumption of household appliances and increase the use of space and has been widely used in a variety of green home appliances, mainly high-end refrigerators. Zisun is grasping the market opportunities, constantly improving product performance and increasing product capacity to meet the growing market demand. 2. Cold Chain Cold chain refers to the special supply of certain products in the process of processing, storage, transportation, distribution and retailing, and use, in which each link is always in a specific low-temperature environment necessary for the product to reduce loss, prevent pollution and deterioration, and ensure product safety. chain system. The cold chain has been deeply integrated into the lives of the public and has a wide range of applications, including primary agricultural products, processed foods, and special commodities (such as medicines and vaccines). One of the core components of cold chain logistics is temperature control and insulation. 2.1 Related Policy In December 2021, the State Council’s “14th Five-Year Plan for the Development of Cold Chain Logistics” pointed out that cold chain logistics is the use of temperature control, preservation and other technical processes and facilities and equipment such as cold storage, refrigerated trucks, and refrigerated boxes to ensure that cold chain products are in the initial stage. 71 / 191 Zisun Annual Report of 2021 Professional logistics in which the whole process of processing, storage, transportation, distribution processing, sales, and distribution is always under the specified temperature environment. Promoting the high-quality development of cold chain logistics is an important means to reduce post-production losses of agricultural products and waste in food circulation, expand high-quality market supply, and better meet the people's growing needs for a better life; it is an important means to support the large-scale industrialization of agriculture, promote agricultural transformation and it is an important foundation for farmers to increase their income and help rural revitalization. It is an important way to meet the individual, quality and differentiated consumption needs of urban and rural residents, promote consumption upgrades and cultivate new growth points, and deeply implement the strategy of expanding domestic demand and promote the formation of a strong domestic market. To improve the quality and safety system of fresh agricultural products “from farmland to table, from branch to tip of tongue”, improve the quality control capability of the whole process of pharmaceutical product logistics, support the implementation of food safety strategy and an important guarantee for building a healthy China. The “14th Five-Year” Cold Chain Logistics Development Plan requires: to improve the development level of refrigerated vehicles, such as accelerating the development and manufacture of light and micro new energy refrigerated vehicles and refrigerated containers to promote new refrigerated vehicles, railway refrigerated vehicles, and refrigerated containers; unitization of transportation vehicles, such as guiding cold chain transportation enterprises to use standardized pallets, turnover boxes (baskets), cages and other transportation units, as well as unitized cold chain vehicles such as cold storage boxes and incubators, and strengthen the circulation and sharing system of standardized cold chain vehicles 72 / 191 Zisun Annual Report of 2021 construction to improve the energy-saving level of cold chain logistics facilities, such as improving the thermal insulation and flame retardant properties of thermal insulation materials in cold storage, refrigerated vehicles, etc. to increase the research and development and application of green cold chain equipment, such as encouraging the use of green, safe, energy-saving, environmentally friendly refrigerated vehicles and supporting equipment facility to emphasize R&D and application of cold storage turnover boxes, thermal insulation packaging, thermal insulation covers, etc. that meet the characteristics of cold chain logistics. Encourage the use of green, low-carbon, high-efficiency refrigerants and thermal insulation consumables In May 2018, “Technical Specifications for Verification Performance Verification of Temperature Control Facilities and Equipment for Cold Chain Logistics of Pharmaceutical Products” stipulates the verification of temperature-controlled warehouses, temperature-controlled vehicles, refrigerators, incubators and temperature monitoring systems involved in cold chain logistics of pharmaceutical products Contents, requirements and operation points of performance confirmation. In March 2021, implement the “National Food Safety Standard Hygiene Specification for Food Cold Chain Logistics” (GB 31605-2020) mandatory national standards to improve and standardize the quality and management level of cold chain logistics services. The healthy and sustainable development of the cold chain logistics market plays an important role in promoting and promoting. 2.2 Industrial Trends With the improvement of people’s living standards in our country, our demand for cold chain is increasing day by day, and the market scale is constantly expanding. According to the “2021 China Cold Chain Logistics Industry Research Report”, from 73 / 191 Zisun Annual Report of 2021 2015 to 2020, the market scale of cold chain logistics will increase from 179.2 billion yuan to 360.4 billion yuan with CAGR 15%. At present, the demand for food cold chain drives the growth of demand for cold chain logistics, and various policies support the expansion of cold chain application scenarios and customer groups. Taking the promotion of food and beverages to the cold chain industry as an example, the demand for cold chain transportation of cold beverages, quick-frozen food, dairy products and agricultural products in my country is increasing. As the penetration rate of the Internet continues to rise, the demand for fresh food e-commerce in online consumption is also increasingly prominent. In addition, pharmaceutical cold chain, chemical cold chain, and electronic cold chain will continue to drive the demand for cold chain logistics. The history of the cold chain industry in developed countries has been more than 150 years, and the development of cold chain logistics is in a leading position in the world, with a cold chain market size of $98.47 billion in North America, $78.94 billion in Europe, and $17.65 billion in Japan in 2020. According to the relevant reports, (1) the cold storage capacity per urban resident in China was only 0.13 cubic meters in 2018, lower than the global average of 0.15 cubic meters and much lower than 0.49 cubic meters in the United States. (2) from 2015 to 2018, the cold chain circulation rates of Chinese fruits and vegetables, meat and aquatic products were increased from 22%, 34% and 41% to 25%, 39% and 63%, respectively. The spoilage rate was controlled at 15%, 8%, and 10% or less, However, there is still a gap with the average cold chain circulation rate of 80%- 100% in developed countries and the corrosion rate of less than 5%. In the post-epidemic era, as the epidemic prevention and control becomes more difficult and the epidemic of the covid-19 may become a new normal, “vaccine + therapeutic drugs” will become the strategy for the prevention and treatment of the covid-19. Vaccinations are accelerating domestically and globally. According to iFinD data, as of the end of October 2021, the total number of covid-19 vaccine doses in the 74 / 191 Zisun Annual Report of 2021 world was 7.087 billion doses, 2.274 billion doses in China, 424 million doses in the United States, 112 million doses in Germany, 99 million doses in France, and 104 million doses in the United Kingdom. 1.063 billion doses in India and 276 million doses in Brazil. The demand for biomedical cold chain driven by the covid-19 vaccination is vigorously driven. In cold chain logistics, the insulation performance of various containers will directly affect the delivery distance of cold chain logistics, the quality stability of goods and other key indicators, which directly affects the product circulation rate and loss rate. The current cold chain insulation materials are mainly based on traditional polystyrene and polyurethane, with the increasing demand for biological products, pharmaceutical products, various types of vaccines, the transport distance is getting longer and longer, the cold chain logistics in each link of the thermal insulation requirements are also increasing. At present, the cold chain insulation materials are mainly based on traditional polystyrene and polyurethane, which have disadvantages such as large volume, short thermal insulation time, and easy generation of pollutants in the production process. It can be seen that the thermal conductivity of VIP board is only one tenth of the traditional materials, which can meet the requirements of long time, extreme temperature and long-lasting stable heat insulation, providing users with longer-lasting stable heat insulation performance and larger storage and transportation space. In addition, the VIP board has better thickness advantage than traditional organic insulation materials, which can improve the space utilization rate of logistics containers and storage space. Combining the various advantages of VIP board, it is expected to gradually replace traditional thermal insulation materials in the future. 2.3 Zisun in Cold Chain Transportation 75 / 191 Zisun Annual Report of 2021 The key material of the VIP board is the VIP core material. The thermal resistance coefficient, physical properties, stability and other core indicators of the VIP core material determine the thermal conductivity and service life of the VIP board. The VIP core material developed and produced by Zisun, relying on the excellent performance of microfiber glass, has a unique pore structure, minimizes heat transfer caused by conduction and convection, and has excellent performance. The uniformity of surface density and thermal conductivity have reached the international advanced level. 3. Green Building Field 3.1 Related Policy The Outline of the 14th Five-Year Plan and Vision 2035 proposes to promote new urban construction, green building materials, assembled buildings and steel structure houses, and build low-carbon cities, emphasizing the acceleration of green transformation of development. The Ministry of Housing and Urban-Rural Development defines green building as “high-quality buildings that save resources, protect the environment, reduce pollution, provide people with healthy, suitable and efficient use space during the whole life cycle, and maximize the harmonious coexistence between man and nature”. In September 2021, the “Opinions of the Central Committee of the Communist Party of China and the State Council on Completely, Accurately and Comprehensively Implementing the New Development Concept and Doing a Good Job in Peaking and Carbon Neutralization”(Zhongfa [2021] No. 36) pointed out that vigorously develop energy-saving and low-carbon buildings, Continue to improve energy conservation standards for new buildings, and accelerate the large-scale development of ultra-low energy, near-zero energy, and low-carbon buildings. Vigorously promote the energy- saving renovation of existing buildings and municipal infrastructure in cities and towns and improve the energy-saving and low-carbon level of buildings. Gradually carry out building energy consumption quota management, implement building High efficiency 76 / 191 Zisun Annual Report of 2021 and energy saving evaluation labels, and carry out low-carbon development performance evaluation in the building sector. The new version of “Green Building Evaluation Standards” (GB/T51356-2019) establishes a new model of green building development that is “people-oriented, emphasizing performance, and improving quality”, and proposes the index system of “safety and durability, health and comfort, life convenience, resource conservation and environmental livability”. Green building should take into account the climate characteristics, geographic environment, natural resources and other factors, and adopt appropriate exterior insulation system, exterior window insulation system, ventilation system, natural lighting, solar energy and building integration, green building materials and intelligent control and other technologies. The Ministry of Housing and Construction, Development and Reform Commission and other departments issued the “Green Building Creation Action Plan”, the proportion of green building area in new buildings in urban areas reached 70% by 2022, star-rated green buildings continued to increase, the level of High efficiency and energy saving of existing buildings continued to improve, residential health performance continued to improve, the proportion of assembled construction methods steadily increased, the application of green building materials further expanded, green residential user supervision fully promoted, the people actively participate in the creation of green building activities, the formation of a social atmosphere that advocates green living. 3.2 Industrial Trends According to the China Building High efficiency and energy saving Association's China Building Energy Consumption Research Report (2020), the building operation phase accounts for 21.7% of the total national energy consumption, and the building operation phase carbon emissions account for 21.9% of the national carbon emissions. According to the UCLA paper “Phase Change Composite Materials for Energy Efficient Building Envelopes”, the energy consumed by heating and cooling needs in 77 / 191 Zisun Annual Report of 2021 all types of commercial and residential buildings accounts for more than 30% of the total energy consumed to operate the building. The insulation performance of building walls in building operation has a significant impact on building energy consumption and indoor comfort. The insulation in the building reduces the dissipation of indoor heat to the outdoors, reduces the energy consumption of building heating and cooling, and improves the comfort of the building. The performance of building insulation materials is affected by the external environment, for example, condensation of water vapor in cold and warm air in the insulation layer can cause deterioration of materials, shorten service life, breed mold and other adverse effects. Common building insulation materials such as organic materials, inorganic materials and composite materials, such as bead rock board, polystyrene particle board, rigid foam polyurethane, rock fiber, mineral fiber, glass fiber, aerogel, etc., and fiber glass has a good market prospect because of its excellent sound absorption and insulation performance, light and soft, affordable and easy to obtain, biosafe. Currently, high-end construction cotton is monopolized by excellent foreign companies, such as Owens Corning and other companies. 78 / 191 Zisun Annual Report of 2021 Owens Corning is a developer, manufacturer and marketer of insulation materials, roofing systems and fiberglass composites, including building materials such as fiber glass insulation, Formica extruded foam panels, Langstone synthetic stone exterior materials and Silentex systems and other composites for solutions in the automotive industry. (Taken from the official website of Owens Corning) 3.3 Zisun and Green Buildings In order to break the foreign monopoly and focus on high quality of life, Zisun is actively laying out dust-free residential air conditioning system and developing and producing energy-saving materials for buildings. At present, Zisun’ team of comfort residential dust-free air conditioning system is actively working to promote product R&D in order to creates a comfortable residential environment that is energy-saving, quiet and dust-free for many customers. In terms of building energy saving, our VIP core material owns the characteristics of good fire resistance, low thermal conductivity, long service life, low energy consumption in the production process, low water absorption, light weight, and easy construction, which can meet the requirements of green buildings for high-efficiency thermal insulation and energy-saving of walls Considering the heat and thermal insulation needs around green buildings, relying on Zisun R&D strength and industry brand advantages in microfiber glass, Sichuan Zaisheng has been set to develop and produce more energy-saving, environmentally friendly and efficient high-end microfiber glass aiming to provide excellent building insulation solutions for green buildings. Zisun has developed a series of green building insulation products with micro glass fiber as the core material. These materials have excellent physical properties, good thermal conductivity, lightweight flame retardant, and low water absorption. 79 / 191 Zisun Annual Report of 2021 It can be widely used in building insulation fields such as household appliances, public buildings, agriculture and animal husbandry, and intelligent workshops. It can also be used with prefabricated buildings, BIPV (Building Integrated Photovoltaic, building-integrated photovoltaics), passive houses, NET-ZERO buildings (Net Zero Energy Building, near-zero energy buildings) and other applications. Zisun will actively expand and promote the application of green building insulation products and contribute to the green building field. 4. Aviation and Aerospace In order to ensure the temperature and comfort of the cabin in flight, the aircraft is installed with an insulation layer between the skin and inner wall which aims to reflect heat radiation or reduce heat conduction, realize the functions of heat insulation, noise reduction and noise reduction in the cabin, improve cabin comfort and reduce aircraft energy and fuel consumption. 4.1 Related Policy 80 / 191 Zisun Annual Report of 2021 The CAAC in “The 14th Five-Year Plan for Civil Aviation Development” requires the improvement of the industry green development policy management system and the improvement of the civil aviation green development capability support system. It emphasizes the application of enhanced new technologies and new materials in aircraft and airports. In detail, the plan, for the green development of the civil aviation industry, proposes specific guidelines which is the carbon dioxide emission per ton-kilometer of transport aviation will be reduced from 0.928 kg in 2020 to 0.886 kg in 2035, and the energy consumption per passenger at the airport will be reduced from 0.948 kg of standard coal to 0.853 kg of standard coal. 4.2 Industrial Trends According to the “Commercial Aircraft Market Forecast Annual Report (2020- 2039)”, China’s aviation market will receive 8,725 passenger aircraft with more than 50 seats in the next 20 years, with an average annual growth rate of the fleet of 4.1% and an average annual growth rate of passenger turnover of 4.3%; China’s fleet will reach 9,641 by 2039. Global air passenger turnover (RPKs) will increase at an average annual rate of 3.73%, with 40,664 new aircraft expected to be delivered. By 2039, the global passenger aircraft fleet is expected to reach 44,400 aircraft, which is the current fleet (23,856 aircraft) 1.9 times. Routine maintenance and repair affect the safety of the aircraft, and aircraft must be inspected according to strict laws and regulations. The interval between inspections is determined by flight hours, flight cycles (landing and takeoff times), and calendar hours. During the inspection and maintenance, the aircraft’s acoustic and thermal insulation blankets are replaced and maintained according to specific standards and actual conditions. With the development of technology and the improvement of quality of life, people have put forward higher requirements for the comfort of transportation, and cabin noise is one of the indicators that passengers focus on. At present, although the airworthiness clause does not impose mandatory restrictions on cabin noise, in order for a model to gain stronger competitiveness in the market, it is necessary to strictly control the noise, 81 / 191 Zisun Annual Report of 2021 vibration and other comfort indicators in the aircraft cabin, and make sure that it is the optimal design is carried out under the premise of considering various factors. Aircraft noise is mainly divided into two categories: cabin noise and external noise. Reducing the noise in the cabin is mainly to improve the comfort of passengers, while reducing the external noise is to meet the airworthiness requirements of the regulatory authorities for the aircraft. Generally speaking, the main noise of the aircraft comes from the aerodynamic noise of the high-speed rotating engine blades and the surface of the aircraft. Reducing engine noise has become an important task in aircraft design. A better aircraft shape design helps reduce the noise generated when high-speed airflow rubs against the surface of the aircraft. The thermal and sound insulation layer laid in the aircraft fuselage also contributes to the reduction of cabin noise. With the increasing global requirements for aircraft energy saving and emission reduction, as well as the maintenance of newly delivered aircraft and existing aircraft, the need of aircraft insulation mat will be also increased from the aspects of quantity and performance. 82 / 191 Zisun Annual Report of 2021 (Fig of Insulation of Aircraft, from Virginaustralia Airline) 4.3 Zisun in Aviation and Aerospace Zisun high-efficiency and energy-saving product, sound and heat insulation blanket, have obtained the test qualification certificate of Commercial Aircraft Corporation of China Limited. This product is made of glass fiber through patented processes such as modification and compounding, which has excellent performance of light weight, flame retardant, waterproof, sound insulation, heat insulation, etc. It can be used in aircraft cabin, ship cabin, subway and other applications with high comprehensive requirements for sound insulation and heat insulation. We have obtained the aerospace quality management system AS 9100 certification and has built an acoustic laboratory with ASTM standard. In addition, the high-silica fibers developed and produced by Zisun have been used for a long time by international well-known aerospace companies, and have reached in- depth commercial cooperation, which is of great significance to develop high-end applications in aerospace. Zisun will continue to make efforts to provide more users with high-quality localized products and services. 5. Emerging Application Areas Achieving peak carbon neutrality and striving to build a clean, low-carbon, safe and efficient energy system is a major decision and deployment made by the Party Central Committee and the State Council. Pumped storage and new energy storage are important technologies and basic equipment supporting new power systems. They have great significance to promoting green energy transition, responding to extreme events, ensuring energy security, promoting high-quality energy development, and supporting the realization of climate change goals. 5.1 Related Policy 83 / 191 Zisun Annual Report of 2021 In July 2021, the “Guiding Opinions of the National Development and Reform Commission and the National Energy Administration on Accelerating the Development of New Energy Storage” requires that by 2025, the transformation of new energy storage from the initial stage of commercialization to large-scale development will be realized. The innovation capability of new energy storage technologies has been significantly improved, the independent and controllable level of core technology and equipment has been greatly improved, and great progress has been made in terms of high safety, low cost, high reliability, and long life. The business model is basically mature, with an installed capacity of over 30 million kilowatts. New energy storage plays a significant role in promoting the process of carbon neutralization in the energy sector. By 2030, full market development of new energy storage can be achieved. The core technology and equipment of new energy storage is independently controllable, and its technological innovation and industrial level are at the forefront of the world. The standard system, market mechanism, and business model are mature and sound, and are deeply integrated with all aspects of the power system. The installed capacity basically meets the corresponding needs of the new power system. New energy storage has become one of the keys supports for the carbon neutralization of the energy sector. The “Opinions” provide detailed planning guidance for specific plans, including coordinating the development of special energy storage plans, vigorously promoting the construction of power-side energy storage projects, actively promoting the rational layout of grid-side energy storage, and actively supporting the diversified development of user-side energy storage. 5.2 Industrial Trends The power system is a stable and balanced system. The energy storage power station is to adjust and buffer between various power sources and power demand, which is equivalent to the role of a reservoir, which can effectively improve the system's ability to regulate voltage and frequency. Energy storage is critical in electricity consumption. 84 / 191 Zisun Annual Report of 2021 With the continuous advancement of the parity process of new energy sources such as wind power and photovoltaics, the installed capacity of new energy sources has continued to increase. However, due to the intermittent and unstable characteristics of new energy power generation, the accompanying energy consumption problem has become increasingly prominent. energy storage power stations can be used to cut peaks and fill valleys and improve power supply reliability. As "new energy + energy storage" has become a development trend, the energy storage power station industry has ushered in rapid development At present, for urban energy storage systems, lead-acid batteries, lithium-ion batteries, etc. are the main ways for electrochemical energy storage systems. VRLA batteries have the advantages of excellent capacity stability, reliable low temperature operation, high cycle charging capacity, low accident risk and low environmental pollution risk, and maintenance-free. It has important applications and wide markets in global urban energy storage systems (Valve-Regulated Lead-Acid Batteries In Energy Storage Stations, Fig from OFFGRIDENERGY) 85 / 191 Zisun Annual Report of 2021 5.3 What Zisun Strives One of the core materials of VRLA batteries is the battery separator made of micro glass fiber. The battery separator is placed in the two pole plates of the battery to prevent the positive and negative plates from contacting each other and cause a short circuit, and adsorb the sulfuric acid electrolyte, which is the core material to maintain the long- term, stable and high-efficiency function of the battery. Important indicators such as microporosity, chemical stability, and mechanical strength of battery separators determine the deep cycle life, charge acceptance and safety performance of VRLA batteries. Zisun produces battery separators, using the self-developed micro glass fiber as the core raw material, which has excellent affinity with water, acid corrosion resistance, temperature resistance, oxidation resistance, and has a large specific surface area and high porosity. The liquid absorption speed is fast, and it has good mechanical strength and is easy to process. Due to the excellent performance of the Zisun microfiber glass, the battery separator products have extremely low impurity content, which ensures the low self-discharge rate of the VRLA battery. We digs deep into the performance of materials, grasps the market demand, and continues to promote the continuous improvement of the performance and production capacity of our battery separator products. IV. The Business of Zisun During the Reporting Period Under the impact of the epidemic of the century, the evolution of the century-old situation has accelerated, and the instability and uncertainty of the external environment have increased significantly. Zisun takes high-quality development as the starting point, focuses on the needs of users for high-quality life, tempers our core competitiveness, and strives hard to give full play to our resilience, cultivate new products, expand new production capacity, and quickly respond to changes in the external environment and market demand. 86 / 191 Zisun Annual Report of 2021 By integrating the advantageous resources of the industry, making full use of the accumulation of long-period technology practice for many years, and deeply exploring the advantages of materials, Zisun independently researches and develops a wide range of high-performance products with full coverage, and carries out innovation and application exploration around the beforehand, processing, and afterwards phrase of clean air.

Solution of Indoor Air Quality Hong Kong of China is the first area to propose legislation on indoor air quality (IAQ). According to the information provided by the Hong Kong Environmental Protection Department. Humans need to breathe every second and clean air is very important for our health. We spend most of our time indoors in our homes, schools, offices and shopping malls. A polluted indoor environment can cause headaches, itchy eyes, breathing difficulties, skin irritation, vomiting and fatigue. Children, the elderly and people with respiratory or heart conditions are more vulnerable to indoor air 91 / 191 Zisun Annual Report of 2021 pollutants. Improving indoor air quality can improve the health, productivity and psychological well-being of indoor populations. Indoor air pollutants originate from the external environment and indoor activities. As shown in the figure below, the composition of indoor air pollutants in rooms with different external environments and different functions is different. If the air conditioning system does not have the function of “clean air”, polluted outside air will be continuously introduced into the room, and many pollutants in the room cannot be discharged, thus deteriorating the indoor air quality. (Picture from International WELL Building Institute) 92 / 191 Zisun Annual Report of 2021 Zisun clean air materials are empowered to efficiently purify the indoor air, remove particulate pollutants, gas pollutants, and ensure individual fresh air volume. According to specific design requirements, constant air volume variable air volume terminals are used to control different rooms and fresh air volume accurately and automatically in the area. 2. Solution of Thermal Comfort Thermal comfort is a state of mind and an expression of people’s ideological satisfaction with heat and cold. Dr. P.O. Fanger proposed an evaluation index characterizing the human thermal response, and this index represents the average value of the hot and cold sensations of most people in the same environment. The factors influencing thermal comfort include thermal radiation, heat and cold, humidity, blowing sensation, clothing, and metabolism, of which the first four indicators are directly related to the air conditioning system. Based on the thermal comfort standard EN ISO 7730, the indoor comfort level is evaluated by the airflow dissatisfaction DR, which is related to the wind speed, temperature, and vortex intensity in the area where personnel stay. The comfort level is divided into three grades A, B and C, corresponding to DR values of 10%, 20% and 30%. When the grade is B, it indicates that more than 80% of the personnel are satisfied with the indoor environment. TROX has four different air conditioning technologies, based on various technical principles such as Kanda effect, thermal plume effect, natural convection and radiation cooling, to meet users’ thermal comfort needs, analyze airflow distribution characteristics, optimize indoor airflow organization by optimizing air delivery, increase indoor radiant heat transfer surface, ensure uniform indoor air speed and temperature distribution, and control the range of vertical temperature gradient fluctuation and cold air sensation. 93 / 191 Zisun Annual Report of 2021 (Picture from Simulationhub) 3. Solution of Indoor Noise According to the “Burden of Disease due to Noise Pollution Report” released by the World Health Organization, noise is second only to air pollution in terms of harm and has become an invisible killer affecting human public health. Studies have shown that prolonged exposure to a noisy environment may lead to delayed reactions, increased annoyance, and harm to the human cardiovascular system, endocrine system, and nervous system. Therefore, a good acoustic environment is vital, which not only enhances people’s attention, but also reduces mental stress and improves sleep. 94 / 191 Zisun Annual Report of 2021 No fans or other mechanical equipment at the end of the room to ensure no sense of cold air, no noise and temperature balance in the room, and silent operation all year round. The operation of ordinary air conditioning system generates airflow noise, radiation noise and over-flow noise, which will interfere with the hearing of indoor people and affect the comfort of life. (Picture from TROX) In accordance with ISO 3741, Trox has built the world’s most advanced acoustic laboratory. The lab is an irregular structure with an overall suspended partition design, which accurately measures airflow noise, radiated noise and insertion loss of HVAC equipment by the reverberation method, and combines the measured sound power with the evaluation standard ARI 885 to provide NC noise values for the indoor occupancy area. The diffuser, valves and other products of Zisun residential comfort & dust-free air conditioning products conform to the aerodynamic principle to avoid airflow noise; products such as mufflers and flow-overs are made of environmentally friendly materials and have excellent noise reduction functions; products are designed with no moving parts , to achieve a good quite effect. 95 / 191 Zisun Annual Report of 2021 Zisun residential comfort & dust-free air conditioning can achieve low air speed, low temperature difference, low noise and mild air supply, ensuring no cold air feeling, no noise and balanced temperature in the room, and a variety of product appearance to meet the needs of various interior design styles, which can provide users with a state of “wind and sunshine”. 1.Variable air volume system The residential comfort dust-free air conditioning system has a unique variable air volume adjustment system, which can be adjusted intelligently according to user needs through the change of air supply volume to achieve room cooling and heating adjustment; there is no need to install fan parts indoors again, combined with reasonable air outlet arrangement to ensure orderly indoor airflow organization and low operation noise; to meet the requirements of different air supply methods, and can achieve independent temperature and humidity control in each room. The VAV system ensures that the direction and flow rate of airflow in the room are carefully calculated to avoid the sense of blowing wind, so that the house can ensure micro-positive pressure relative to the outdoors and avoid the outside polluted air or humid air from directly penetrating into the room, and also realize the flow of indoor air from the comfort area to the auxiliary function area, and control the odorous air and humid air in the room can be discharged in an organized manner and not scattered. TROX provides residential RSD diffuser with special blade structure, through the airflow simulation and experiment, comprehensive air supply, air supply angle and installation height and other factors, to achieve the best air supply, to avoid cold air sense blowing sense, High level of user comfort. The series has exquisite appearance, various styles, easy to decorate with, to meet the personalized aesthetic needs of users. 96 / 191 Zisun Annual Report of 2021 2.

The common pipes of traditional central air-conditioning systems accumulate dust and produce a breeding ground for harmful microorganisms such as bacteria, mold, etc., resulting in secondary pollution of indoor air; Zisun residential dust-free and comfortable air-conditioning system pipes are protected by HEPA level to keep dust- free and clean. There is secondary pollution. 3. Low Operating Energy Consumption Zisun residential comfort and dust-free air conditioning system replaces the traditional HVAC system's cooling and heating function, floor heating and fresh air system and other systems. During the construction stage, the system was upgraded to reduce the floor height occupation of the house and save the indoor floor height for users. In the actual use stage, the system not only provides users with a high-comfort indoor space, but also consumes less energy than traditional multiple systems. 98 / 191 Zisun Annual Report of 2021 (Project scene of Zisun residential comfort and dust-free air conditioning system) In a comprehensive manner, the Zisun dust-free and comfort air conditioning system can run all year round and is supported by an intelligent control system to ensure that the user's indoor environment maintains the following environment all year round. 99 / 191 Zisun Annual Report of 2021 Indoor temperature distribution uniformity: set temperature plus or minus 0.5K Indoor wind speed distribution uniformity: 0.2m/s to 0.3m/s Noise level40cmh/person PM2.5 <25u/m3 Zisun residential dust-free and comfort air conditioning system can be organically combined with its thermal insulation glass product line to create a comfortable and pleasant living environment, excellent indoor air quality, and near-zero energy consumption. Considering the needs of building layout, orientation, shape factor and use function and the climatic conditions of the building, the thermal insulation glass product is used in the non-transparent maintenance structure of the building to optimize the overall air tightness of the building and improve the thermal insulation performance of the building, reduce indoor and outdoor energy transfer, reduce building cooling and heating energy consumption. As the construction of ecological civilization in China continues to progress, the concept, awareness and demand for green buildings are gradually increasing throughout the society. Zisun will follow the direction of the policy, pay close attention to 100 / 191 Zisun Annual Report of 2021 technology improvement, increase product capacity, and continuously meet the market demand for green building. (2) Mobile Space Field Such as New Energy Vehicles Zisun has set up Chongqing Langzhirui New Material Technology Co., Ltd. to focus on the research and development of high-performance, long-life, anti- biochemical weapons-grade automotive air conditioning filter element, which can effectively filter fine particles, gas pollutants, as well as bacteria, viruses, dust, aerosols, plant pollen, mold spores, dust mite excrement, etc. The filtration effect of particles ≥0.3μm can reach 99.97% and above, allowing drivers and passengers to enjoy clean and healthy air in the car. It can also prevent dust from accumulating inside the air conditioning system and prolong its service life. The high-efficiency PTFE membrane products produced by Baoman New Materials, a subsidiary of Zisun, have been adopted by well-known international companies and applied to the air-conditioning filter elements of automobile cabins, providing stable, efficient and reliable “clean air” guarantee for many users. We will persistently explore the application prospects of various “clean air” materials and technologies in the field of new energy vehicles, and strive to provide “clean air” cabin environment protection for new energy vehicle users worldwide. (3) Animal Husbandry Zisun has developed a special filter material with high efficiency, low resistance, high temperature and high humidity resistance for 0.3μm particles with a filtration effect of more than 94%, which is the leading level in the world. Our product index is at the international level, which provides reliable application solutions to effectively reduce the spread of virus and solve the key technical problems of preventing and controlling African swine fever. 101 / 191 Zisun Annual Report of 2021 (Filter for Pig House) According to users’ feedback, Zisun fresh air filter material and equipment for livestock industry have been put into use, which has improved the air quality inside the pig house, accelerated the growth rate of pigs and improved the survival rate of pigs. In 2021, Zisun will continue to actively explore and provide “clean air” solutions and quality services to high-end domestic pig suppliers. In the first half of 2021, U-air was awarded the title of Grade 5A supplier of Shepherd Plains, and became the supplier of Xinda Animal Husbandry, and cooperated with Guangxi Nongken Group and Yurun Group. Affected by the downstream pig cycle expansion progress, the new air application project of sub-pig barn slowed down during the reporting period. Zisun will continue to make efforts to promote the application of clean air core products in the field of animal husbandry, actively promote our products and services through various ways such as industry exhibitions, provide materials and equipment for different customer needs, and strive to improve our profitability. (4) Advanced Manufacturing Fields (Semiconductors, Panels, Precision Instrument Processing, Biomedicine, And Medical Health etc.) For high-end manufacturing fields such as semiconductor, panel, precision instrument processing, biomedical, medical and health care, etc., different links in their 102 / 191 Zisun Annual Report of 2021 production activities have different requirements for "clean air". The typical application requirements for "clean air" are clean rooms. (Fig of Typical Clean Room Structure) A cleanroom is a controlled environment where pollutants like dust, airborne microbes, and aerosol particles are filtered out to provide the cleanest area possible. A cleanroom can be classified into different levels of contamination depending on the amount of particles allowed in the space, per cubic meter. Cleanrooms also control variables like temperature, air flow, and humidity. Most cleanrooms are used for manufacturing products such as electronics, pharmaceutical products, and medical equipment. Cleanrooms work to remove pollutants, particles, and contaminants from outside ambient air. Outside air is first circulated to a filter system. The filters (either HEPA or ULPA) then clean and decontaminate this outside air according to their specifications. The filtered air is then forced into the cleanroom. Additionally, contaminated air within the cleanroom is forced outside the room by registers, or it is recirculated back into the filters, and the process restarts. There are a wide variety of reasons that a company may need a cleanroom. for the manufacture of something is easily affected by contaminants or particles in the air. Some common industries that regularly use cleanrooms, such as: high-end 103 / 191 Zisun Annual Report of 2021 manufacturing, Research facilities, pharmaceutical production, medical laboratories, electronic part production, aerospace industry nanotechnology production, optics and lens manufacturing, military applications.

In 2021, we will insist on focusing on our main business, taking “high quality development” as the starting point, responding efficiently to the market demand for “Clean Air” And “High Efficiency And Energy Saving”, continuing to refine our three major capabilities of “continuous cost reduction, continuous R&D investment and ecological development”, promote the construction of new production capacity, continue to invest in research and development, and insist on new product development. (1) Analysis of The Main Financial Data of The Company During the reporting period, Zisun realized an operating income of RMB 1,619,710,800. The main business income was RMB 1,590,257,500, a decrease of RMB 274,307,500 compared with the same period of last year, or 14.71%, of which the 107 / 191 Zisun Annual Report of 2021 clean air segment operating income was RMB 896,106,500, a 29.55% decrease compared with the same period last year, and the high-efficiency energy-saving segment operating income was RMB 694,151,100, compared with last year, an increase of 17.15% over the same period. Zisun realized a net profit attributable to the parent company of RMB 249,471,400, and net profit attributable to the parent company of RMB 225,618,200 after deducting non-recurring gains and losses. 1. Description of the Decrease in Operating Income In 2020, the sudden outbreak of Covid-19 in China, Zisun quickly responded to the demand of the government and users and promptly adjusted the company’s strategy, relying on the technical strength and production capacity of its subsidiary Shenzhen Zhongfang melt-blown materials, and utilized its clean production workshop to produce a batch of melt-blown materials for individual protective masks and multi-series personal protective masks. The operating revenue of our masks and melt-blown materials in 2020 was RMB312,578,000, accounting for 16.76% of the main business in the period. In 2021, as the global ecvid-19 continues, the supply chain and production capacity of other domestic companies have been restored and melt-blown materials and personal protective materials are no longer in short supply. Our masks and melt-blown material operating revenue was $33,534,100, a significant decrease from the same period last year, accounting for only 2.10% of the main business revenue for the period. The decline in our operating income in this reporting period is mainly due to the decrease in demand for masks and melt-blown materials. In addition, due to the multiple influences of industrial policy and consumption cycle of pig breeding industry, the demand for fresh air for pig barns from domestic livestock breeding industry customers has slowed down since the second quarter of 2021, and thus the demand for filter materials and equipment for fresh air for pig houses has decreased. For the whole year of 2021, we achieved operating income of RMB100.6123 million from the sales of filter 108 / 191 Zisun Annual Report of 2021 materials and equipment for fresh air in pig houses, a decrease of RMB 136.9302 million. Combined with our business strategy, product structure, market demand and other comprehensive situation, after deducting the masks and melt-blown materials for operating income analysis, operating income of Zisun in 2020 is RMB 1,551.968 million and in 2021 operating income is RMB 1,586.1767million. As shown in the chart below, reviewing our operation from 2015 to 2021, our main business remains for continuous growth. (Fig of the revenue without masks and melt-blown materials) 2. 2021 Revenue Analysis In 2021, the sales revenue of “Clean Air” products was RMB 896.1065 million, accounting for 56.35% of the main business revenue, a decrease of 11.87% compared with the same period last year. The main reason is that the revenue of melt-blown materials and masks drop significantly in 2021. For the more, Clean Air Equipment has been affected by factors such as the fluctuation of the construction cycle of downstream 109 / 191 Zisun Annual Report of 2021 users whose sales revenue is RMB 397.068 million with a decease of 10.41% from 2020. In 2021, “high-efficiency and energy-saving” products achieved sales revenue of RMB 694.1511 million, accounting for 43.65% of the main business revenue, an increase of 11.87% over the same period last year. Benefiting from the demand for “High-Efficiency and Energy-Saving” products in many application fields around the world, our VIP materials and AGM separators continue to have strong demand. Among them, Chongqing Paper Research Institute efficiently completed the relocation of the AGM separator production line and actively put it into production. In 2021, the AGM separator shipments reached 8,137.11 tons, an increase of 18.06% compared with it in 2020. 3.The Superimposed Impact of The Global Shipping Situation on Revenue and Profits The Ministry of Transport pointed out that, due to the impact of multiple factors, the demand for international container transport has been released centrally since June 110 / 191 Zisun Annual Report of 2021 2020, and the ship capacity of major liner companies has been basically fully committed to the market except for the necessary repair and maintenance. With the spread of the overseas Covid-19, ports in the United States, Europe and other places have continued to experience severe congestion since the fourth quarter of 2020, resulting in chaos and reduced efficiency of the international logistics supply chain, extensive delays in ship schedules, and seriously affecting operational efficiency. The Suez Canal blocking incident and the outbreak of the Covid-19 in South Asia such as India since March 2021 have exacerbated the contradiction between supply and demand in the logistics supply chain. The tight shipping capacity and rising freight rates have become a global issue. During the reporting period, the freight-to-value ratio of the export products increased due to the rise in shipping costs. Zisun actively took various ways to cope with the situation, including multiple coordination of container supply, price adjustment and delivery method adjustment, etc., and made every effort to protect the export supply chain and reduce the shipping cost. However, in the context of the sharp rise in global sea freight, the export orders have been delayed and the shipping cost was still higher than the same period last year. The main export products are “Clean Air” materials and “High Efficiency and Energy Saving” materials. During the reporting period, our overseas sales revenue amounted to RMB 535.0392 million, a decrease of 3.11 % compared with the same period last year.

The Company's Discussion and Analysis on The Future Development of The Company All details refer to Chapter 3 in this report. 135 / 191 Zisun Annual Report of 2021 (四)可能面对的风险 1. Risk of Changes in Raw Material Costs In the cost composition of micro glass fiber, natural gas costs account for a relatively high proportion of the total cost, and the price of natural gas has a greater impact on the price of micro glass fiber. Fluctuations in natural gas prices in the future will directly cause fluctuations in the price of micro glass fiber. If the price and production cost of micro glass fiber fluctuate significantly in the future, it will directly affect the company's net profit. 2. Risk of Changes In Export Tax Rebate Policy. Our export sales revenue accounted for about 33.77% of the total combined main business revenue of 2021. With the changes in the country's economic situation, the country may adjust the relevant export tax rebate policies in the future. If the export tax rebate rate of our main products is reduced or cancelled, it may have an adverse impact on the net profit. 3. Risk of exchange rate changes. Due to the large proportion of our export business, the current exchange rate in the international market fluctuates frequently. If the exchange rate fluctuation of RMB against the US dollar and the euro continues to increase in the future, the company will face the risk of exchange loss due to exchange rate fluctuations. 4. The Risk of Large Book Balance of Accounts Receivable. Zisun implements a consistent and prudent credit policy, and the increase in the book balance of accounts receivable is mainly due to changes in the sales revenue and customer structure. 136 / 191 Zisun Annual Report of 2021 However, if the book balance of accounts receivable continues to rise sharply in the future, on the one hand, the operating cash flow will continue to decrease, which will put the company under greater financial pressure, which may lead to the risk of not being able to raise funds in time for necessary research and development and investment in fixed assets. On the other hand, the possibility of bad debts in the company's accounts receivable increases, increasing the risk of uncollectible accounts receivable. 5. The risk of talent shortage. The rapid growth of the company is accompanied by the growing demand for talents, especially the demand for high-end technical talents and management talents is obvious in the short term. 6. Goodwill impairment risk. There is a large goodwill in the process of merger and acquisition. If the performance of the acquired party develops in an unfavorable direction in the future, there may be impairment of goodwill, which will have a certain impact on the company's performance. 137 / 191 Zisun Annual Report of 2021 Chapter 4 Company Governance I. Description of Corporate Governance During the reporting period, according to the relevant laws and regulations such as the Company Law, the Securities Law, and the Corporate Governance Guidelines for Listed Companies, as well as the requirements of the Articles of Association, Zisun has continuously improved its corporate governance structure and internal control system.

During the reporting period, the company strictly followed the “Inside Information Insider Management System” to keep the inside information confidential and the insider's registration and filing work, and strictly control the insider to the minimum scope and ensure that the major information will not be leaked during the window period. Our directors, supervisors, and senior managers did not use inside information to buy or sell the company's stock during the sensitive period.
