This image subset contains images of an apparent rally of the Nationalist 48th Army Division (陆军第四十八师) that happened in SW China during WWII, with speeches, parades, group oaths, patriotic slogan practice, singing, and martial competitions with awards, and a final banquet.
Several images show Zheng Tingji (郑庭笈) as commander of the 48th Army Division (陆军第四十八师 ), and he held that post from January 1944, to May 1945 (1944年1月任第48师师长，1945年5月任云南昆明机场守备司令), so the images are from that timeframe.
Based on some of the KMT officials in some of the images, and the terrain recorded in the images, this rally was probably in Fohai county (佛海县), in far SW Yunnan province, adjacent to Burma.
