Answer and explanation:
The Communist Party and the Kuomintang clashed from August 1927 until December 1936, and then again from March 1946 to May 1950. Their conflict stopped from 1936 to 1945, because they worked together to oppose the Japanese invasion.
Prior to the civil war, communists and nationalists were both members of the same administration, and they collaborated to combat the Chinese warlords who still governed portions of the country. After defeating the warlords, the Nationalists turned on the Communists and began ruthlessly eliminating them.
While the Nationalists pursued them, a party of Communists commanded by Mao Zedong escaped into the rural mountain. The Nationalists were never able to catch up, and the communists were able to consolidate their power in the area. As the corrupted officials of the Kuomintang abused many peasants, they all became enthusiastic about the Communist regime, and Communism grew in popularity.
The Nationalists fled to Formosa, or modern-day Taiwan, after a series of setbacks. The US aided them in establishing a Nationalist administration in the country. The Communist government then seized control of mainland China and began brainwashing citizens into believing that Communism and Russia were great, while America, democracy, and nationalism were terrible. Then Mao Ze Dong made a series of errors that resulted in the deaths of many individuals. Firstly, he forcibly removed farmers from their fields and forced them to live in communes in order for them to socialize and assist others. This failed, however, since the farmers were not internally motivated to farm the land; it wasn't their property, and they couldn't retain whatever they raised or sell the products for profit. Then he attempted to boost farm output and the military, neglecting China in many other areas, including non-military equipment manufacture and the majority of everyday products. This would lead to the Chinese seeking independence from communist rule and subsequently democracy.
