Han Youwen, a Salar general in the National Revolutionary Army and member of the Kuomintang (Nationalist Party), directed the defense of the city of Xining during air raids by Japanese planes. Han survived an aerial bombardment by Japanese planes in Xining while he was being directed via telephone from Ma Bufang, who hid in an air raid shelter in a military barracks. The bombing resulted in human flesh splattering a Blue Sky with a White Sun flag and Han being buried in rubble. Han Youwen was dragged out of the rubble while bleeding and he managed to grab a machine gun while he was limping and fired back at the Japanese warplanes. He later defected to the Communist People's Liberation Army, serving in numerous military positions and as vice chairman of Xinjiang. He had led Chinese Muslim forces against Soviet and Mongol forces in the Pei-ta-shan Incident.
