Before japan launched the war of aggression against China, it killed a person in the northeast, and if this person did not die, the Japanese might not dare to fire the first shot. He is Zhang Zuolin, that is, Zhang Xueliang's father. At that time, the Japanese were in the northeast, but also depending on his face, he might be careless, he would be picked up by Zhang Zuolin, so some people would think that Zhang Zuolin did not die, and the War of Resistance would not need 14 years.
Before Zhang Zuolin became a warlord, he was also a bandit, and he who had been a bandit still had the breath of a bandit on his body. Ordinary people did not dare to provoke him, even the incomparably arrogant Japanese, who were in the northeast at that time, needed to see Zhang Zuolin's face. At that time, the Northeast Army was also very strong in all aspects, and its weapons and equipment also surpassed the Central Army, and in the face of such a Northeast Army, the Japanese army naturally did not dare to act rashly.
Moreover, at that time, Zhang Zuolin and the Japanese were cooperative, and the Japanese were also bent on wooing him, but although Zhang Zuolin cooperated with them, he did not think of treason. And Zhang Zuolin did not give the Japanese a little face, when a Japanese hit his people, he directly gave his subordinates a holiday, let them go to the street to kill the devils, which made the Japanese still very afraid of him, it can be said that Zhang Zuolin is a stumbling block on their way to invade China.
Although the Japanese high-level deliberately tried to win Zhang Zuolin over, the military in the northeast at that time could not hold back. So he set a trap, created an accident, and killed Zhang Zuolin, which is also known as the Huanggutun Incident. After Zhang Zuolin's death, the Japanese began to invade the northeast in a frenzy, and at that time, Zhang Xueliang did not order resistance, so that the Japanese quickly occupied the northeast, if Zhang Zuolin was still alive, the Japanese could not succeed.
