The period from 1999 to 2009 is a decade of hard work and fruitful results. In 2000, the company transformed from Jixi light industry chain factory to Jixi Huangshan Industrial Co., Ltd. Fang Weizhong was the general manager of the company. Adhering to the position that human resources are the first wealth of the company, the company actively carried out various management and professional skills training, organized rich and colorful staff activities, implemented the annual awards of excellent employees, and continuously improved the professional ability and team cohesion of the company. At the same time, we fully introduced and implemented the ISO9001 quality management system, further improved the control level of process quality and product quality, and stabilized the company's position as the best supplier of high-quality accessories in the national chain industry. On this basis, general manager Fang Weizhong has a long-term vision and realized that to further develop, we must create our own products and brands. In 2002, Anhui Huangshan Zhongyou Chain Manufacturing Co., Ltd. was established with Huangshan industry as the main investor. With the introduction of professional and technical talents, a large amount of R & D funds was invested to develop its own brand "shuaiqiao" and "Zhonglian" steel transmission and conveying chain products. Through years of efforts and recognition and feedback from the market and customers, "shuaiqiao" and "Zhonglian" brand trademarks were recognized as famous trademarks in Anhui Province and Xuancheng City in 2009.
