A reference to the error of the "Left" adventurism represented by the dogmatist Wang Ming from January 1931 to January 1935. With the support of the Communist International and its representative, Pavel Mif, Wang Ming and his followers gained the leading position in the Central Committee at the Fourth Plenary Session of the Sixth CPC Central Committee, held in January 1931. Politically, they blurred the demarcation line between the democratic revolution and the socialist revolution and put the struggle against the bourgeoisie on a par with the struggle against imperialism and feudalism; they ignored the marked change in China's class relations after the September 18th Incident of 1931 (Japan's invasion of northeast China) and regarded the intermediate forces as "the most dangerous enemy". They also continued to push the "theory of making the cities the center of the Chinese revolution" and held that the Red Army should seize the key cities in order to achieve victory first in one or more provinces, which would then lead to nationwide victory. Militarily, they first practiced adventurism and, later, lapsed into conservatism and fleeing away. Organizationally, they practiced sectarianism and followed a policy of "ruthless struggle and merciless blows" towards those who disagreed with their erroneous views. The "Left" adventurism of Wang Ming dominated the Party for four years and brought heavy losses to it and the whole revolutionary cause. In January 1935, the Political Bureau of the Central Committee held a meeting in Zunyi, Guizhou Province, which established the correct leadership of the new Central Committee represented by Mao Zedong, thus ending the domination of Wang Ming's "Left" adventurist line in the central leading organs of the CPC.
