From 1937 to 1945, the Women's Anti-Japanese National Salvation Association in the Jincha Ji Border Region performed core duties including women mobilization, ideological enlightenment and social integration during the behind-the-enemy-lines War of Resistance against Japanese Aggression. From the perspective of ideological and political education, this organization relied on a sound grassroots network, combined political guidance, cultural education and production practice, and established a mobilization system adapted to rural society and the real conditions of local women. Its content design oriented by women's practical demands, hierarchical and categorized mobilization approaches, as well as multi-party coordinated guarantee mechanisms effectively prompted women in the border region to step out of families into public society and shift from passive acceptance to active participation in the War of Resistance against Japanese Aggression. The relevant practices not only provided solid support for the victory of the War of Resistance against Japanese Aggression, but also offered historical references and practical experience for grassroots ideological and political guidance for women, targeted service delivery and innovation of mass work in the new era.
