HANGZHOU - Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee, and other CPC leaders on Tuesday afternoon visited the site in Jiaxing, east China's Zhejiang province, where the first CPC National Congress was held in 1921.

The first CPC National Congress was originally held in the French concession area in Shanghai in July 1921, but moved to a boat on Nanhu Lake in Jiaxing due to an interruption by local police.

Xi and other leaders also visited the Nanhu Lake Revolution Museum.

Twelve delegates attended the first CPC National Congress in July 1921, representing more than 50 CPC members nationwide.

On Oct 18, more than 2,300 delegates attended the 19th CPC National Congress, representing over 89 million CPC members of the country.
