Sun Mingjiu, a native of Xinmin, Liaoning, was an angry hero who captured Chiang Kai-shek in Huaqingchi, and later defected to the Japanese as traitors. After liberation, Sun Mingjiu was hired as a counselor to the Shanghai Municipal Government. Sun Mingjiu and Zhang Xueliang have a deep affection, and in 1990, when General Zhang Xueliang was asked if he wanted to meet someone if he revisited the mainland, Zhang Xueliang was the first to mention Sun Mingjiu.
In the early morning of December 12, 1936, the Xi'an Incident, which shocked China and foreign countries, broke out, and the Northeast Army and the Seventeenth Route Army acted in concert to detain Chiang Kai-shek and many Kuomintang military and political leaders who accompanied Chiang Kai-shek. In this incident, Sun Mingjiu, the battalion commander of Zhang Xueliang's guard, became famous for leading his troops to successfully capture Jiang, and became a well-known hero for catching Jiang.
Sun Mingjiu joined the Northeast Army in 1927, was selected to go to Japan in 1928 to study at the Army Non-Commissioned Officer School, and after returning to China, he served as an instructor under Zhang Xueming in Tianjin, Zhang Xueming was Zhang Xueliang's younger brother, and Sun Mingjiu was Zhang Xueming's classmate. In 1931, Zhang Xueliang was appointed deputy commander-in-chief of the Kuomintang Navy, Army and Air Force.
Later, Sun Mingjiu successively served as Zhang Xueliang's confidential staff officer and battalion commander of the Guard Battalion, and became one of Zhang Xueliang's confidants. In July 1936, in order to establish the internal leadership core of the Northeast Army and achieve its goal of profoundly transforming the Northeast Army, Zhang Xueliang established a secret political organization "Anti-Japanese Comrades Association" in the army, with Zhang Xueliang personally serving as the chairman, and the Young Zhuang officers led by Sun Mingjiu and others as its main members. These young officers were young and vigorous, flesh-and-blood, and ideologically radical, and they had long been dissatisfied with Chiang Kai-shek's policy of keeping the country at home and abroad
After the incident, the commanders of the Northeast Army were extremely angry and demanded that the murderer be punished. On February 4, Zhou Enlai ordered Liu Ding to send Ying Detian and Sun Mingjiu to the Soviet zone of the Red Army for temporary refuge. As a result, many military division commanders angrily declared their allegiance to Nanjing and obeyed the central dispatch orders, and some people took the initiative to take action against the Communists, and Gao Fuyuan, who had first helped Zhang Xueliang connect with the CCP, was shot.
At this point, the Northeast Army as a group collapsed and ceased to exist. Zhang Xueliang never dreamed that it was he who personally founded the Anti-Japanese Comrades Association, and it was the middle and lower-ranking officers he carefully trained who finally sent the Northeast Army, which he had tried so hard to preserve and did not hesitate to launch a mutiny, into the grave.
With the peaceful settlement of the "Xi'an Incident" and the beginning of the second cooperation between the Kuomintang and the Communist Party, the situation of national anti-Japanese reunification gradually took shape; according to the spirit of the Party Central Committee Meeting, in order to clarify the relationship with the "Xi'an Incident," the CPC was unwilling to take in Ying Detian, Sun Mingjiu, and others, who had to leave the Soviet zone. Sun Mingjiu first hid in the Tianjin Concession, then in the Shanghai Concession, and then, later, simply defected to the Wang Jingwei government as a traitor. According to Ying Detian's 1956 confession, Sun Mingjiu served as a counselor and military attaché in the Office of Counselor and Military Attaché of the Wang puppet government in the spring of 1943, a special commissioner and fu'an commissioner in northern Henan in mid-year, and was promoted to deputy commander of Shandong pseudo-security in the following year for meritorious service. They also went to the troops of the Northeast Army to plot a rebellion and coaxed them to defect to Japan and become traitors. In the middle, Ying Detian once defected to his subordinates to serve as the director of the Henan Pseudo-Education Department.
