Dear customers and all employees:

        The golden ox bows its head to bid farewell to the old year, and the auspicious tiger leaps forward to bring good fortune! On the occasion of the New Year holiday, Zhongzi Technology extends its holiday greetings and best wishes to customers who have long supported our development, to all hardworking employees and their families, and to people from all walks of life who are concerned about us!

       Recalling the past, the turbulent years are thick. 2021 was an extremely extraordinary year. In the face of the sudden COVID-19 and the severe and complex development situation, all employees have never forgotten their original intention, forged ahead, based on their posts, and had the courage to take on responsibilities, to promote production development to achieve new results and create a new situation. This year, we focused on safety and development, and successfully passed the second level evaluation of safety production standardization by the Provincial Emergency Department. We focus on innovating laws and exploring new paths, with a focus on business model innovation. We are exploring the public welfare pilot program of "exchanging old for new long-term warranty" for catalytic converters, and the related research content has been reported by the People's Daily. We focus on strong leadership and aggregation capabilities. As a leading enterprise in the industry with comprehensive strength ranking among the top three in China, we have successfully listed on the Shanghai Stock Exchange's Science and Technology Innovation Board in October this year after 16 years of hard work, opening a new journey for the company's development. We focus on seizing opportunities and promoting cooperation. For our customers, we spare no effort to ensure product performance and quality, and provide them with the best service. Through years of accumulation, the company has achieved mass supply to mainstream engine manufacturers such as Yuchai, Yunnei, Shangchai, Liuji Power, and Xiaokang Power, as well as mainstream vehicle manufacturers such as CNHTC, FAW Jiefang, BAIC Foton, and Dachangjiang. With everyone's joint efforts and witness, Zhongzi Technology's work has become more and more practical year by year, its performance has improved year by year, and its weather has become newer year by year!

       These achievements cannot be achieved without the trust and support of customers, the hard work and efforts of all employees, and even more importantly, the silent efforts and support of family members behind them!

       Looking at this morning, the heavy responsibility lies on our shoulders. 2022 will be a year full of hope, a year of rapid development for the company after going public. A new year requires a new atmosphere and more importantly, new achievements. In the context of reducing pollution and carbon emissions, peaking carbon emissions, and achieving carbon neutrality, we must never forget our original intention of becoming a leader in the Chinese industry and a world leader. We must keep in mind our mission of "controlling air pollution and realizing the dream of blue sky and white clouds", continue to deepen our cultivation of new materials and new energy industries, further strengthen our technological innovation capabilities, research and develop key technologies and killer technologies, break through "bottleneck" technologies, achieve independent and controllable core technologies, maintain our scientific and technological innovation attributes, participate in the battle against pollution prevention and control with practical actions, win the battle to defend the blue sky, and contribute to the dual carbon cause.

       On the occasion of the New Year holiday, I wish everyone a happy New Year and a happy family. May the Year of the Tiger bring good luck and prosperity!
