On the morning of September 19, 2018, foreign investors from Beihai Export Processing Zone "Macau-Beihai Portuguese National Industrial Park" came to our company for investigation and research. The general manager of Cheng Hang Company Zeng Shushen accompanied the investigation. Foreign investors visited the company's remanufactured products and remanufacturing workshop and held a symposium at which they exchanged views on the future of the duplicator remanufacturing industry. The industrial construction of the country is very useful.
