Feng Yuxiang, whose real name is Ji Shan, was originally from Chao County, Anhui Province. (now Chaohu City, Anhui Province) is known as "General of Christ", "General of Surrender" and "General of Cloth". There has been a constant debate about the number of defectors from Feng Yuxiang. Some people say it three times and some people say it eight times, but many historians and researchers agree that the exact number of defections of Feng Yuxiang in his life should be nine times. So for such a large number of defectors, people nicknamed him "the general who defected."

Although he is known as the "general who defected to the enemy", his evaluation in history is mixed. Although Feng Yuxiang left the scene and rose up many times in the warlord melee, he was full of persistence in territory and desire for power, which was a typical old warlord behavior. However, after the outbreak of the Anti-Japanese War, he always adhered to the concept of the Anti-Japanese War, no longer obsessed with personal gains and losses for the national justice, and actively ran in various anti-Japanese war activities. He was a patriotic soldier.

Premier Zhou Enlai said in mourning for General Feng Yuxiang: "General Feng Yuxiang was a staunch democratic fighter transformed from an old soldier; Although like all historical figures, due to the limitation of political vision, he inevitably has some defects, but the defects cannot be hidden, and General Feng Yuxiang's contribution to China's democratic cause will be immortal.
