The Tenth Plenary Session of the Eighth Central Committee of the Chinese Communist Party was held in Beijing from September 24 to 27, 1962. At the session it was pointed out that the entire Party was confronted with the following urgent task; to continue to do a good job in readjusting, consolidating, filling out and raising the standards of the national economy by implementing the general principle of taking agriculture as the foundation and industry as the leading factor in developing the national economy. The ``Decision on Further Consolidating the Collective Economy of the People's Commune and Developing Agricultural Production'', ``Regulations on Work in the Rural People's Communes (Revised Draft)'', ``Resolution on Questions Concerning Commercial Work'' and other documents were adopted at the session. Mao Zedong spoke on the questions of classes, the overall situation, the contradictions in China at the time, and unity within the Party. He spoke in absolute terms about class struggle that still exists within certain scope in socialist society and broadened its scope, expanding on the view he advanced after the anti-Rightist Campaign in 1957 that the contradiction between the proletariat and the bourgeoisie remained the principal contradiction in Chinese society. He went a step further and asserted that the bourgeoisie would exist and try to stage a comeback throughout the historical stage of socialism. At the same time, he also pointed out that class struggle should not be stressed at the expense of economic readjustment. At this session the so-called black wind (referring to views demanding full recognition of the serious and difficult situation of that time), the tendency to return to individual farming (referring to the practice of fixing output quotas for each household) and the ``evil wind of reversing correct verdicts'' (referring to the demand for re-examining and rehabilitating Party members and cadres who had been unjustifiably criticized or punished during the movements after 1958 and to the petition presented by Peng Dehuai to the CPC Central Committee and Mao Zedong) were all wrongly criticized.
