Abstract: After the victory of Anti-Japanese War in 1945, the national government in the secondary capital Chongqing decided to hold a nationwide celebration ceremony of the victory under the name of the nation on World Anti- Fascist War and China’s Anti-Japanese War Victory Day and issued Implementation of Celebration Ceremony nationwide. Chongqing was the first to establish “Celebration Ceremony Preparatory Committee in the Secondary Capital” and held a grand ceremony in Jiaochangkou on September 3rd. Immediately after that, “Celebration Ceremony Preparatory Committee in Shanghai”, with its office on No. 65, Gedeng Road (today’s Jiangning Road), was established to prepare for the celebration ceremony in Shanghai. However, the ceremony in Shanghai was postponed to October 10th because the administrators of the allied armies, national armies and Shanghai municipal government failed to arrive in Shanghai on the Victory Day. The ceremony was held in Shanghai Race Club with unprecedented spectacular scene and fervent atmosphere. It was the first grandest civil “celebration” ceremony as well as an outstanding ceremony under the name of the nation held in Shanghai after the withdrawal of concessions and the unity of municipal authorities. However, the ceremony has not aroused enough attention of scholars up to now. Focusing on Shanghai, this paper explores the preparation and concrete process of the ceremony and discusses the relationship between the celebration ceremony and politics based on related archives and other materials.
