Although surrounded, over half the guerrillas were able to slip through the encirclement and make good their escape to Jehol. Later Feng's force joined in opposing the invasion of Jehol, and was forced to draw back into the area inside the Great Wall. Subsequently he participated in Feng Yuxiang's Chahar People's Anti-Japanese Army, as its Fourth Route Army commander in chief, against Japan and their Manchukuoan allied forces in the Dolonor area of Chahar. Following the dispersal of that force by Chiang Kai-shek, his force was formed into the 91st Division which Feng commanded until July 1938 when the Division suffered heavy casualties during the battle of Wuhan. He later left the army and went to Hong Kong to engage in business. In 1949 he returned to China assuming directorship of the Jilin Provincial Sports Committee. He also served in various government offices. Feng died on September 14, 1963.
