Abstract:Zhejiang is a key germinating province of Xi Jinping's socialist thought with Chinese characteristics in the new era. Since the 18th National Congress of the CPC, some major Xi Jinping's important expositions on the working class and trade union work stem from his thinking about the new situation in Zhejiang province. This paper focuses on elaborating the content of Xi Jinping's expositions on the work of working class and trade unions during his administration in Zhejiang province, and the internal agreement with his important expositions since the 18th National Congress.
