Li Lisan
In 1925, Liu became a member of the Guangzhou-based All-China Federation of Labor Executive Committee. During the next two years he led numerous political campaigns and strikes in Hubei and Shanghai. He worked with Li Lisan in Shanghai in 1925, organizing Communist activity following the May Thirtieth Incident. After his work in Shanghai, Liu traveled to Wuhan. He was briefly arrested in Changsha and then returned to Guangzhou to help organize the 16-month-long Canton-Hong Kong strike.
