Which type of insurgent approach did the chinese communist use to conquer china after world war 2?

Protracted popular war.

Explanation:

Protracted people's war is a military-political approach originally exhibited by the Chinese Communist extremist and executive leader Mao Zedong (1893–1976). It needs far more support and exercise to regulate and supervise populated centers and societies than it does to convey insurgent operations from the forests or hills. Securing the power of a city needs many personages to give protection while satisfying the population's requirement for food, water, light, and pharmaceutical care. Such requests would use up many of the supplies an insurgent system would need to fight an extended war of reduction, so it is not uncommon for insurgents to evacuate cities and foist the liability of considering for their communities upon the state. The goal of this program is to push the state to extend its sources in succession to satisfy the requirements of the people, including protection.
