On February 4, over 20,000 workers of the Beijing-Hankou Railway went on strike, paralysing the 1,200-kilometre-long railway. On February 7, Wu Peifu, aided by imperialists, assembled more than 20,000 troops and policemen to suppress the striking workers in cold blood at Jiang'an, Zhengzhou, Changxindian and other railway stations. This became known as the “February 7 Massacre,” which shocked the country and the whole world Fifty workers were killed, more than 300 were wounded and over 40 were thrown into jail. Many workers' families were looted.

The CPC held its Third National Congress in Guangzhou. Attending the congress were 30-odd delegates who represented 420 Party members. According to the agenda, the congress was mainly to discuss the question whether the entire membership should join the KMT. It accepted the “Resolution on the Relationship Between the Chinese Communist Party and the Kuomintang” adopted by the Communist International on January 12 of the year and decided that all the CPC members join the KMT in the capacity of individuals for the benefit of establishing the united front of various democratic classes.
After the conclusion of the congress, Party organizations in various places carried out ideological work among the Party members to remove their doubts about joining the KMT. In the meantime, the Communist encouraged Dr. Sun Yat-sen and Liao Zhongkai to reorganize the KMT.
