Li Shimin was outnumbered in Chang 'an. Why can he kill his brother and force his father?

For Li Shimin, to launch a coup, three people must be caught in one sweep, namely Prince Li, King Li Yuanji of Qi and Tang gaozu. Once one of them is released, it will cause an uproar, especially Li He. If they have to leave, it will mean the failure of the coup. So, how to get these three people together and get them all done in a short time? After some planning, Li Shimin decided to use his father Tang Gaozu.

The day before the change of Xuanwu Gate, Li Shimin secretly played to Tang Gaozu, "Building slaves, Yuanji and Yin Defai, fornication harem". Li Shimin also said, "I don't owe my brother anything. Now I want to kill him, as if to avenge the world and Jiande. I died in vain today. I never disobeyed my relatives. My soul went underground. It's a shame to see a thief! " Li Yuan was cheated by Li Shimin. He immediately said, "When you ask questions, you should participate early." Li Shimin's "catch all" plan has been initially realized!

When Li and Li Yuanji enter the palace, they will certainly bring their own guards. If they give up halfway, it will be difficult to guarantee success. The best place is Xuanwu Gate, because it is the gateway to the palace. Not only can Li and Li Yuanji's guards not enter, but they can't carry weapons into the palace. Therefore, the key to the coup is the commander-in-chief of Xuanwu Gate! At that time, the general stationed in Xuanwu Gate was named Changhe, "leading athletes to the north gate".

Clever Zhang He seems to have lost trust in Crown Prince Li, but in fact he secretly turned to for help. In order to win over Chang 'e, Li Shimin also gave Chang 'e a lot of money before the Xuanwumen Rebellion. "Give him a golden knife, thirty pieces of gold." . In addition, Li Shimin gave Zhang He dozens of golden knives to buy off the soldiers of Xuanwu Gate. The long river played an important role in the changes of Xuanwu Gate. Without his support, Li Shimin would not even have succeeded.

On the day of the coup, he led some cronies to sneak into Xuanwu Gate, waiting for the arrival of Li and Li Yuanji. After discovering Li, he did not hesitate to bend his bow and take an arrow, and an arrow shot his younger brother Li. After some entanglement, Wei Chijingde killed Li Yuanji. However, the situation has changed. Thai uterus and Qi Wang Mi's soldiers stormed Xuanwu Gate, and others were once at a disadvantage.

Li Shimin soon sent Wei Chijingde to the palace again, because another important person was out of control, and that person was Tang Gaozu. Wei Chijingde, dressed in armor and armed with a spear, broke into the palace and took control of Tang Gaozu. At that time, the war had not stopped, and Wei Chijingde forced Tang Gaozu to order that "all soldiers belonging to the king of Qin should be punished", but Tang Gaozu dared not refuse. Three days later, Tang Gaozu was forced to write a letter conferring Li Shimin as Crown Prince, and abdicated a few months later.
