Li Shimin, Emperor Taizong, was a rare monarch in history. He played a vital role in helping his father Li Yuan establish the Tang Dynasty. It was he who urged Li Yuan to rise up and overthrow the Sui regime. It was he who urged Li Yuan to March into Guanzhong and seize this strategic position. It's him again. At the age of eighteen, he became the commander-in-chief of Tang Jun, killing countless enemies. The blood of the enemy was sprayed all over his sleeves, and finally the surrounding mountains were razed to the ground. Li Shimin's contribution is so great that Tang Gaozu must be unhappy. There is a simple reason. Li Shimin has made such a great contribution. Where should we put it? You can't make him a vice emperor. Will Li Shimin be happy not to let him be the deputy emperor? If he is unhappy, he will be in trouble. He is so good at fighting that no one can beat him. In addition, Tang Jun's valiant soldier and elite troops were also brought out by Li Shimin. It is obvious who they listen to at the critical moment. Helpless, we adopted the method of raising Li and Yuanji, and promoted them to suppress the people. But these two people are not simple. Li always wants to grab the class and seize power. Well, here's your chance. Li Yuan went to Renzhi Palace for the summer, and Li launched a coup. After learning that, he called Li to Renzhi Palace. I tried to kill him, but he thought it was still nearby, so he let Li Yima go. After the Renzhi Palace incident, Li Yuan was both afraid and sad.

Li is worried that if the coup was successful, he would have been beheaded. If Li's coup is successful, what will he do? There are only three ways, murder, house arrest and filial piety to the emperor's father. Of course, the best way is to honor the emperor's father, which will sound better and look better, and avoid the crime of patricide. However, there is a premise, that is, no power will use Li Yuan as a call to threaten Li's rule. Were there such conditions at that time? No. Don't talk about Yuanji. Li Shimin will be the first to quit. He will certainly play the slogan of "respecting the deep and prosperous" and organize the army to be diligent. Once Li Shimin raised his arm and shouted, Tang Jun would be surging. Why? Because the army followed Li Shimin all the way into Guanzhong and followed Li Shimin to the Western Seas. It was Li Shimin who established this army. No famous player like Qin was promoted by Li Shimin. Li Can Cheng Jian is in charge of Li Shimin? Can't handle it, the only thing he can do is kill Tang Gaozu. No one, then why are you still diligent? Killing Tang Gaozu can also forge testamentary edicts to attack Li Shimin. Anyway, people are dead, who will verify the authenticity of the testamentary edict?

Li Yuan is a politician. It is impossible for him not to see this. He has reason to be afraid. Tang Gaozu should be very sad, too. He has long known that Li Shimin should be a prince, whether in character, talent or military exploits. However, this Li Shimin is so powerful that Tang Gaozu is a little afraid of him. When Li Shimin becomes a prince, will he honestly stay in the East and wait for his father to travel to take over? Tang Gaozu is fine. There is no information about Li Yuan's "essence" in historical materials, but the history books have taken pains to record all kinds of affairs of Li Yuan's "illness", which shows the essence of Li Yuan's constitution. God, Dad is in such good health. When will Li Shimin take over? What if he gets tired of waiting and plays a trick of Renzhi Palace? So the solution is to let the capable second son lead the army to war, let the less capable eldest son Li contain it in front of the prince, let the situation be controlled and sit firmly on the throne of the emperor.

Unexpectedly, this Li is not a fuel-efficient lamp, but actually launched a coup, which failed his painstaking efforts. Fortunately, in this coup, He and Yuanji were away, and Li's plot failed to come true. How to stabilize the situation, Tang Gaozu again remind of Li Shimin. He called Li Shimin and said solemnly, "When you get to Chang 'an, go back to Chang 'an as soon as possible, and I will make you a prince. I can't kill my own son like Emperor Wen of Sui Dynasty. I became the king of Shu in feudal times, and the army of Shu is very fragile and will not pose a threat to you. If he can follow your orders in the future, you can let him stay there. If he doesn't listen to your orders, you can easily take care of him. "

According to Tang Gaozu's will, Li Shimin got up and returned to Chang 'an that night. Although Tang Gaozu didn't order the killing to be completed, his heart has changed greatly and he was abandoned. Son to launch a mutiny to kill you, you have to keep him, let him be king of Shu, why did Tang Gaozu do this, does he really want Li Shimin to be a prince this time? Not necessarily. Li Yuan is a politician, and he will not easily change the strategy of "rejuvenating the people". Actually, it's the same. After Li Shimin left, Tang Gaozu changed his mind. During the Renshou Palace incident, Li Yuan hated the completion, but he didn't kill him or let him go. He promised to make Li Shimin a prince again, but he soon changed his mind. After arriving in Chang 'an, he quickly sent Li back to Beijing to continue to manage state affairs as a prince.

Tang Gaozu cheated Li Shimin for the third time. The history books record why Tang Gaozu did it, because he listened to his concubines' excuses for the completion. Actually, it's not that simple Li Yuan is a politician and an outstanding politician. In his eyes, concubines are just toys. How could he destroy the Great Wall because of some of their words? What plays a key role here is his political strategy of "prospering the people". As long as he doesn't kill or let Li go, you can understand that keeping Li is useful. Why? Contain Li Shimin.

We don't know how Li Shimin felt when he was cheated again. But what is certain is that he was completely disappointed in Tang Gaozu. Actually, it's exactly the same After the Renzhi Palace incident subsided, Li, who did bad things, was deeply appreciated, but his second son who saved his life was always scolded. Tang Gaozu is a great hero. Heroes have their own lofty sentiments. After coming back from Renzhi Palace and resting for several months, Li Yuan led a large team to hunt in the southern suburbs of Chang 'an. This time, Li Yuan learned his lesson and took his three sons, Cheng Jian, Shimin and Yuanji, to avoid a recurrence of the Renshou Palace incident. On the hunting ground, Li Yuan ordered his three sons to have a shooting competition. Tang Gaozu's action seems ordinary, but it is actually a mystery. He knew that three sons were at odds, just like three explosives, but he gave each of them a torch. As long as one explosive charge is ignited, the consequences are unimaginable.
