Major contents: At the congress, Mao Zedong delivered the political report On the Coalition Government; Liu Shaoqi made the report On the Revision of the Party Constitution; Zhu De delivered the military report On the Battlefield in the Liberated Areas; and Zhou Enlai made an important speech On the United Front. The congress worked out the Party's political line which was to "boldly mobilize the masses and expand the people's forces so that, under the leadership of our Party, they will defeat the Japanese aggressors, liberate the whole people and build a new-democratic China". The new Party Constitution adopted at the congress stipulates that "the Communist Party of China takes the Mao Zedong Thought that integrated Marxist-Leninist theory with the practice of the Chinese revolution as the guideline for all its work". This helped the Party get consolidated and united in an unprecedented way, laying a foundation for the full victory against Japanese aggressors and later the nationwide victory of the people's democratic revolution.

At the First Plenary Session of the Seventh CPC Central Committee, Mao Zedong, Zhu De, Liu Shaoqi, Zhou Enlai, Ren Bishi, Chen Yun, Kang Sheng, Gao Gang, Peng Zhen, Dong Biwu, Lin Boqu, Zhang Wentian and Peng Dehuai were elected to the Political Bureau of the Central Committee.
