In August 2009, after more than a year of research and development of a new product-aluminum thatch, we finally had an interview. First of all, we just made some recommendations to our long-term customers. I didn't expect a good response at that time. The recommendation of old customers to their friends and customers was actually the best encouragement to our company at that time. Seeing the sales volume in the first month, the company leaders affirmed our achievements and efforts made in the R&D process, and then we applied for relevant patents for this product. Now, after several years of development, our R&D company and our products have been improved, from the previous electrostatic process to a better high-tech process to fluorocarbon process, from a single product to product diversification, from the recognition of old customers to the recognition of the industry. In the development of the past few years, we have received more support from the original market.
