Zhang can be said to be a famous warlord in history, but Zhang was afraid of being assassinated in the northeast, so he paid great attention to the security arrangements around him, and even paid attention to his own security, which led to several interesting things.

One day, Zhang didn't return to his home until late at night. When he wanted to enter his home, he met a guard who was watching the door. The name of this guard is Li Debiao. Originally, he was just an ordinary guard, but after being transferred to the Zhang family, he paid special attention to safety. Therefore, when Zhang returned to his home late at night, he didn't know Zhang, so he just wouldn't let Zhang in, but Zhang was making it clear. Not only did the guards not release him, but they also angrily called themselves Zhang's father and threatened to shoot Zhang if he took one more step. Zhang was so frightened that he had to call his adjutant to pick him up. After realizing what happened, Zhang felt that the guard was very responsible, so he was transferred to his side, and the guard protected Zhang for many years until he was killed on the train with Zhang.

It is precisely because of this escort that Zhang Cai was able to establish its own foundation in the northeast of that year. At that time, political assassinations were common. If we don't pay attention to our own safety, we will die if we are not careful. At that time, Zhang's education of his soldiers was very strict, which led to such an interesting scene. Many people think that Zhang is making a mountain out of a molehill, but if he is really making a mountain out of a molehill, he will not be killed in vain.
