Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee, who is also Chinese president and chairman of the Central Military Commission, and other members of the Standing Committee of the Political Bureau of the CPC Central Committee Li Keqiang, Li Zhanshu, Wang Yang, Wang Huning, Zhao Leji and Han Zheng visit the site where the first CPC National Congress was held in 1921, in Shanghai, east China, Oct. 31, 2017. On Tuesday morning, Xi led the other six members of the Standing Committee of the Political Bureau of the 19th CPC Central Committee to the sites where the first CPC National Congress was held. In 1921, the delegates representing about 50 CPC members nationwide convened the first CPC National Congress in late July in Shanghai, but moved to a boat on Nanhu Lake in Jiaxing of east China's Zhejiang Province due to the harassment of local police.
