Because of Japan’s large-scale aerial bombing of Chongqing and the surrounding mountainous natural environment during the Anti-Japanese War, shelters became important places where the residents of wartime Chongqing evaded attacks by Japanese planes. In addition, the differences between the public and private bomb shelter facilities reflected the high and low, noble and humble people in the shelters, indicating the social class differences in wartime Chongqing. Shelters, especially public shelters, also provided places for socializing, recreation, and they had political and economic functions. Thus, bomb shelters became new public living spaces. Living in bomb shelters also became an important component of the daily lives of the residents in wartime Chongqing. Discussing their daily lives in the shelter allows us to not only understand and know the diversity and complexity of the daily lives of Chongqing’s wartime citizens but also reveals the significant impact of the all-encompassing invasion waged by Japan at the micro level.
