For 30 years, we have honed impetuosity, patience, precision and excellence. This is the media's evaluation of Geng Jiasheng, the representative of the 17th National Congress of the Chinese Trade Union. As a front-line worker, Geng Jiasheng led the team to complete more than 500 product process preparation and drawings improvement projects such as wire drawing machine and rubber crepe machine, and more than 400 production processes such as tower crane lifting part and rewinder chute. Integrating the craftsman spirit of "pursuing excellence and excellence" into his heart, this old craftsman is demonstrating his new mission with practical actions, and will bring the voice of front-line technical workers to the 17th National Congress of the Chinese Trade Union.
