Everyone, after Japan's surrender in 1945, the Chiang Kai-shek government, on the one hand, thought of punishing prisoners of war and traitors in order to invigorate the country's prestige and win the hearts and minds of the people. But on the other hand, they were also worried about irritating Japan, after all, Chiang Kai-shek also needed japanese troops to maintain law and order in certain areas. Therefore, at the ceremony of surrender, Chiang Kai-shek specially approved that there was no need for Okamura Ningji to hand over his saber. In addition, Yan Xishan also hired a large number of Japanese troops, formed a ten general brigade, and equipped them with tanks, and its wolf ambitions were well known to passers-by. Folks, that's why the Kuomintang gave so much preferential treatment to Japanese prisoners of war.

But in stark contrast, in the course of the 14-year War of Resistance Against Japanese Aggression, the Japanese killed Chinese prisoners of war, even civilians, and that was not soft. Like the Lushun Massacre, the Nanjing Massacre, etc., it was quite cruel. Not only that, they also cultivated a large number of traitors, which are said to be more than hundreds of thousands. According to historical records, after the Battle of Wuhan in 1938, the War of Resistance Against Japanese Aggression entered a stalemate stage, and the shortcomings of the insufficient strength of the Japanese army were increasingly exposed. In order to break this situation, Okamura proposed to Emperor Hirohito that it would be better to rebel against several powerful figures in the upper echelons of the Kuomintang, such as Li Zongren. Yes, apart from Chiang Kai-shek, the most powerful person at that time was Li Zongren.
According to historical records, the agent responsible for plotting against Li Zongren was named Xia Wenyun, who had a record of studying in Japan. After Xia Wenyun contacted Li Zongren, at first he also wanted to plot against Li Zongren and complete his task, but he was unexpectedly suppressed by Li Zongren's aura, and in the end, he was countered by Li Zongren. Since Xia Wenyun was born in Dalian (from the late Qing Dynasty to the surrender of Japan, Dalian has long been in a Japanese occupation state) and grew up in the Japanese colonial culture from beginning to end, the Japanese do not think that Xia Wenyun will have any feelings for the Republic of China, so there is no doubt that Xia Wenyun will be opposed by Li Zongren.
Before the outbreak of the Sino-Japanese all-out war, Li Zongren was busy fighting with the Nanjing side and had little contact with Xia Wenyun, until after the outbreak of the War of Resistance, things changed. Japan's large-scale invasion of China required a large number of translators who were proficient in Japanese and Chinese bilinguals, and Xia Wenyun was able to become a translator for senior Japanese generals. During the Battle of Taierzhuang, Xia Wenyun provided Li Zongren with a large amount of information with the significance of influencing the overall situation, which played a great role in the victory of the Battle of Taierzhuang. After that, Xia Wenyun also provided a lot of information that would help the War of Resistance to Li Zongren.
After the victory of the War of Resistance Against Japanese Aggression, Xia Wenyun was arrested by the Chongqing side for adultery, and then after a court trial, he was released without any evidence, and the strange thing is that Li Zongren was silent and closed his mouth about the things that Xia Wenyun had provided him with a lot of intelligence. This must start from the domestic political environment after the end of the War of Resistance. After the end of the War of Resistance Against Japanese Aggression, the Kuomintang once again fell into serious infighting. At this time, the only warlords who could compete with the Nanjing side were the Gui clan (Li Zongren as the leader), and Li Zongren also coveted the presidency.
However, Chiang Kai-shek, as the president of the Kuomintang for several years, was skilled in political struggle, and after the end of the War of Resistance, the people were very angry with the officials who had secret contacts with the Japanese side during the War of Resistance. If Li Zongren admitted that he had secret contacts with the japanese translation officers, he would probably be taken by Chiang Kai-shek to make a big fuss and stir up public opinion, which would be very unfavorable to his position as president, so Li Zongren could not restore his identity for Xia Wenyun.
