Fascinating photo of a crew working out in the open on a non-American aircraft somewhere in southern China. This is likely a Japanese Nakajima Ki-84 Hayate which the Chinese air force received after the war. The two people on the right should be Chinese, and the crew who are working at maintaining the aircraft near the engine are Japanese and Chinese crew. The CAF used Ki-84s and Ki-43s which Japanese left in China during late 1945 to mid 1946 by 18th FS and 19th FS, 6th Group. (Thanks to Gary Lai for info on this image!)
