His Northeast Army is well-equipped and has a large number of people, but Zhang can achieve such achievements thanks to the Japanese helping him behind his back. He cooperated very closely with the Japanese and signed many articles to greatly improve the weapons and equipment of his army. However, when Zhang was alive, he did not really betray the sovereignty of Northeast China. He just played tricks on the Japanese and used them to make his army stronger, but he was also secretly guarding against the Japanese. Signing numerous traitorous treaties, but not implementing them, made the Japanese very dissatisfied with him. Finally, they blew up Zhang's in order to support a puppet in the northeast again.
Zhang's death had a great influence on Northeast China, and Zhang Xueliang, who took over his post, failed to keep the family business in the end. However, although Zhang was killed, his Northeast Army is still there, especially his seven sworn brothers, who are still in charge of the overall situation in Northeast China. These people are important contributors to Zhang's achievements in Northeast China. They are also veterans of the Northeast Army, and they have great prestige. These seven people are Zhang, Tang Yuli, Feng, Zhang Jinghui, Wu He.
As the eldest of eight people, Ma Longtan was also a famous figure in his early years. He is a generation of Confucian generals, and his relationship with Zhang is somewhat complicated. Later, he was also relieved of his military duties. Since then, Ma Longtan has been retired, and he didn't do much in the army. After Zhang was killed, he also lived in seclusion completely, but he also paid attention to integrity, preferring to die rather than cooperate with the Japanese, and finally got a good end.
Wu's second child is also a pillar. He has a close relationship with Zhang and has made many contributions to the stable rule. Later, when Zhang retired, he was ready to hand over all military power to Wu.
It's a pity that such an outstanding figure finally died when Huang Gutun greeted Zhang. He is the only one of these brothers who was killed with Zhang.
The third son, Feng, was also a famous local bandit in his early years. His relationship with Zhang is not very good, and there have been many armed conflicts between them. Later, Feng failed. He gave up the struggle for power and chose to go into business and start an industry, which also achieved great success.
Lao Si Tang Yuheng is also very close to him. Tang Yuheng has saved Zhang's life many times, so Zhang is also very kind to him and gives him great power.
After Lao Zhang's death, Tang Yuli continued to assist Xiao Zhang, but his ability was insufficient. Later, in the face of Japanese aggression, the performance was very bad, and he gave up Jehol directly and became the object of national condemnation. Later, Tang Yuli lost military power and lived in seclusion in Tianjin, and finally died unsatisfied.
Young Zhang Jinghui is the only traitor among these brothers. Zhang Jinghui is ambitious and has been in charge of the army. After Zhang's death, he has been fidgeting. Later, he directly took refuge in the Japanese and was eventually arrested by the Soviet Union and died in prison.
Old six Sun Liechen is the most capable one among them. He is also loyal to Zhang. Unfortunately, he died young before Zhang was killed.
Lao Ba Zhang Xiangzuo and Lao Zhang have a closer relationship. Many people think they are brothers. Zhang has been helping Lao Zhang. After Lao Zhang died, he continued to assist Xiao Zhang. In the end, Zhang also got a happy ending and founded Jilin University, which is also a career. Together with Zhang, these seven brothers formed the Feng system, and their rise and fall also directly affected the rise and fall of Northeast China.
