Abstract: The traditional Chinese rural society is composed of large and small clans, which is a typical rural clan society. After the failure of the Great Revolution, the Communist Party of China entered the rural society to carry out the agrarian revolution and establish the red regime. It has carried on the comprehensive transformation and reconstruction to the rural society and changed the rural clan society under the old order. Through the construction of political power, the CPC overthrew the power of the clans and realized the democratic rights of the peasants. Through land reform, the economic foundation of the clan was removed and Soviet economy was established. Through the revolutionary culture, the Party forged the clan culture and renewed the old values of the people. This movement involved a wide range of people and was committed to changing the old social structure, order and concept. It made great achievements and was also an important starting point of the overall social reform movement led by the CPC.
