Abstract: During the War of Liberation, the Communist Party of China called on urban regimes of liberated areas to organize the mobilization of civilian war service to support the frontline. Under the circumstance of lacking experience and with the relevant instructions of the CPC Central Committee and the Northeast Bureau, Harbin Municipal Party Committee experienced a long term exploration. To represent the interests of city dwellers, they proposed the public slogan at first. The sophisticated systems of requisition and mobilization were also established. Finally, they mobilized the city residents to support wartime service work effectively through ideological guidance and material compensation.

Key words: War of Liberation, city, mobilization, northeast
