After Wu stepped down, he lived in poverty and Zhang Xueliang often helped him. However, after losing the three northeastern provinces, Zhang Xueliang still mercilessly cursed Zhang Xueliang, making Zhang Xueliang afraid to see him from now on. Later, he only sent money to Lao Wu, but he didn't dare to face him. Japan kept wooing him during its invasion of China, but he flatly refused. After the outbreak of War of Resistance against Japanese Aggression, he actively offered suggestions for the war of resistance. Although trapped in the Japanese occupation area, he never colluded with the Japanese puppet government and died during the Anti-Japanese War.
Wu defended the national justice and saved the last section. After the victory of the Anti-Japanese War, the National Government held a state funeral for him and posthumously awarded him as a first-class general in the army.
Dong said to the comments:
"Although Wu is also a warlord, there are two things that are very different from other warlords. First of all, Guan Heyue is a great figure whom he worshipped all his life in the history of our country. After the failure, he didn't go abroad or live in the concession. ..... It is true that many people boast that he can practice the preface when he is out of power. Second, Wu has been an official for decades, ruling the territory of several provinces and leading hundreds of thousands of soldiers. He has no private savings, no land property and an innocent name. Compared with the warlords of the same period, it is finally commendable. "
