After the Japanese invasion of Manchuria, he raised a volunteer force by linking up with other citizens in the and Ji'an areas during late 1931 and announced the establishment of his army in March 1932.
In April, 1932 Tang Juwu revolted in Huanren, establishing the Liaoning Self-Defense Corps. Wang Fengge's unit and other groups of Big Swords became part of Tang Juwu's force. On May 7, 1932, Wang led his force and with Commander Fang Chun of the Huinan anti- Japanese force jointly attacked and occupied the Liuho county seat, and proclaimed the revolt against Japan in a circular telegram. Wang's unit of 1,000 men, suddenly increased to 5,000, and he organized them into six brigades.
By the end of February 1933, most of the large volunteer armies had fled to the Soviet Union, from where they were eventually repatriated. However Wang did not flee and fought on in a guerrilla unit, and continued to harass the Japanese and Manchukuoan forces for many years in Liaoning. Wang Fengge was captured in 1937 after a three day battle and was then executed, along with his wife and child.
