The CCP's success in gaining the support of the rural population during the Sino-Japanese War was multifaceted. Firstly, their land reform policies promised and sometimes delivered land redistribution, directly appealing to the peasants' immediate interests. Secondly, the CCP's guerrilla warfare tactics, which involved the local population in the war effort against the Japanese, fostered a sense of community and resistance. Thirdly, CCP cadres worked to improve local living conditions, promoting literacy and health campaigns. This grassroots approach, coupled with effective propaganda portraying the CCP as the true defenders against Japanese aggression, resonated strongly with the rural populace.

The Yan'an Soviet served as a crucial training and strategic planning ground for the CCP's military strategies and tactics. During this period, Mao Zedong and other CCP leaders developed the concept of "People's War", which emphasised guerrilla warfare, mobilisation of the peasantry, and fighting a protracted war. This approach was significantly different from conventional military tactics, focusing instead on flexibility, mobility, and utilising the terrain to their advantage. The experience gained in organising and executing guerrilla warfare in Yan'an laid the foundation for the CCP's military successes in both the Sino-Japanese War and the subsequent Chinese Civil War.

The CCP's land reform policies had profound consequences for the traditional social structure in rural China. By redistributing land from landlords and wealthy peasants to poorer peasants and landless workers, these reforms disrupted the existing feudal hierarchy. This reallocation challenged the centuries-old landlord-tenant system, leading to a significant shift in power dynamics in rural areas. The land reforms also empowered the peasantry, who formed the majority of China's population, and increased their allegiance to the CCP. These reforms were instrumental in breaking down traditional social structures, paving the way for the CCP's ideological and political indoctrination in rural communities.

During the Sino-Japanese War, the CCP and KMT exhibited distinct political and military strategies. The KMT, led by Chiang Kai-shek, primarily engaged in conventional warfare and sought to defend major cities and communication lines. This approach often led to heavy casualties and limited success against the better-equipped Japanese forces. In contrast, the CCP, under Mao Zedong's leadership, employed guerrilla warfare tactics, focusing on rural areas and mobilising peasant support. Politically, the CCP used the war to propagate their image as the true defenders of China, capitalising on the KMT's failures and corruption. This strategy helped the CCP gain widespread support and credibility.

Mao Zedong's early life had a profound impact on his leadership style and political ideology. Born into a peasant family in Hunan Province, his experiences with rural poverty and traditional Chinese culture influenced his later focus on rural peasantry as the backbone of revolution. Mao's education, which combined classic Chinese texts with exposure to Western political thought during his time at Hunan First Normal University, shaped his blend of Marxist-Leninist ideology with Chinese characteristics. His participation in the May Fourth Movement further radicalised him. These experiences contributed to Mao's pragmatic approach to revolution, favouring guerrilla warfare and mass mobilisation over orthodox Marxist focus on urban proletariat.
