On November 13, 2022, Associate Professor Li Fuzhou, a materials science expert and senior engineer from Wuhan University of Technology, and others visited our company to guide technology research and development and production process improvement work. Our chairman and general manager provided a detailed introduction to our company's basic information, main products, production processes, etc. to the visiting experts. Professor Li and his team provided optimization suggestions for our company's modified polystyrene board production process after inspecting the production site, which was very beneficial. Both parties also discussed future cooperation directions and other matters.
