 Afterwards, the Second United Front completely broke down and Chinese Communists leader Mao Zedong outlined the preliminary plan for the CPC's eventual seizure of power from Chiang Kai-shek.Mao began his final push for consolidation of CPC power under his authority, and his teachings became the central tenets of the CPC doctrine that came to be formalized as "Mao Zedong Thought".The communists also began to focus most of their energy on building up their sphere of influence wherever opportunities were presented, mainly through rural mass organizations, administrative, land and tax reform measures favoring poor peasants; while the Nationalists attempted to neutralize the spread of Communist influence by military blockade of areas controlled by CPC and fighting the Japanese at the same time.
