基层组织是共产党的全部工作和战斗力的基础。善于依靠坚强的基层组织来联系、团结和动员群众以实现党的奋斗目标,是中国共产党最有特色的优良传统之一。全面抗战爆发前,中国共产党提出了抗日民族统一战线的政策,而上海是党的白区工作的最重要阵地之一,是全国的经济、政治中心, Grassroots organizations are the foundation for all the work and combat effectiveness of the Communist Party. It is one of the most distinctive and fine traditions of the Chinese Communist Party to be good at relying on strong grassroots organizations to connect, unite and mobilize the masses in order to achieve the Party’s goal of struggle. Before the full-scale anti-Japanese war broke out, the CPC put forward the policy of the anti-Japanese national united front. Shanghai is one of the most important positions for the party’s work in the white area. It is the country’s economic and political center.
