On October 29, 2021, the "Intelligent Two-cylinder Dewatering System" and "H & E Standardized Dyeing System" designed for Leica, Germany, held a global listing conference at the Kempinski Hotel in Shanghai. The five-year project is finally facing the public. The research and development cycle of medical devices is so long, especially the development of some principles and functions. Even the corresponding national standard can not be found. We can only continue to develop and wait for the improvement of the system. After years of clinical practice and experiments, we finally waited for this day. The efforts of two generations of designers finally saw the moment when the flowers bloom. I would like to thank the two excellent designers, Xu Tong and Xu Feng. Only by insisting day after day can they have today's beautiful results.
