The dispute between Li Shimin and Li Jiancheng for the crown prince completely changed the next historical trend of the Tang Dynasty. In the change of Xuanwu Gate, Li Shimin won the battle, and only then did he have the next rule of Zhenguan. However, a few days before the Xuanwumen Incident, it is recorded in the Zizhi Tongjian that the crown prince Li Jiancheng invited Li Shimin to a banquet, and as a result, he was poisoned in the wine that Li Shimin drank, and as a result, the King of Qin "vomited blood for several liters" after returning to the West Palace, but fortunately did not harm his life. Because of this, there was the next change of XuanwuMen. It's just that Li Shimin has already vomited blood, so why didn't this poisonous wine hurt his life?
Lee built
In fact, there are several main reasons. The first point: Li Jiancheng was very worried when he was poisoned, and it is likely that he did not put enough poison in the wine to kill him. This can be reflected in Wei Zheng's body, Wei Zheng often advised Li Jiancheng to get rid of Li Shimin's misfortune as soon as possible in the plan of the two of them to compete for the throne, but Li Jiancheng was soft many times and could not bear to kill his own siblings.
What's more, the history books record that Li Jiancheng has a generous personality, and his personality has led to his hesitation when doing things, and he can't cut the grass and remove the roots. Therefore, when poisoning, Li Jiancheng is likely to only want Li Shimin to be disabled, rather than poisoning Li Shimin on the spot.
The second point: Li Shimin drank less poisonous liquor than he could kill. Since it was a banquet built by the prince, he must have already made plans in his heart, and Li Shimin knew that this was a feast at the Hongmen Gate, but he couldn't do it without going. A tense situation had already formed between the brothers, and Li Jiancheng's intention to murder him was clear.
Therefore, when drinking and eating in the Prince's Mansion, Li Shimin must have some concerns. Of course, he can't eat or drink, so he can only eat as little as possible and drink less to reduce the chance of his own death. It was because he realized this that he escaped death, and you vomited a few mouthfuls of blood, not lost your life.
Li Shimin
Third point: Ancient poisons were not pure enough to cause death, and the unit of measurement at that time was different from today's society. When it comes to deadly poisons, it is inevitable that they are inseparable from the dose and purity, and poisons that are not pure and insufficient in dose are really not fatal; the so-called leaving the dose to talk about poisons is a hooligan. In fact, the vast majority of ancient poisons are biological poisons, which will not cause people to die instantly, especially with emergency measures to induce vomiting as a response, and will not lead to death.
Of course, because the role of ancient poisons has been exaggerated in recent costume TV dramas, people always feel that one point is enough to kill a person, but in fact, this is just an exaggeration. Secondly, the numerical records in ancient times are not necessarily real references, and the units of measurement at that time were different from those of today, so the "vomiting blood and counting liters" in historical documents inevitably has some exaggerated meanings and cannot be taken seriously.
Li Yuanji
The fourth point: Li Jian cost did not have the intention of killing Li Shimin, he was more afraid of losing both sides, so Li Yuanji picked up the cheap. In the historical dramas related to the Tang Dynasty, Li Jiancheng is always portrayed as a fool. However, this was not the case, and he had also followed his father Li Yuan to make great military achievements, and his merits were not necessarily under Li Shimin. How could such a person be a fool?
If he really killed Li Shimin at this banquet, his position as crown prince would inevitably be insecure, so that the final beneficiary would be Li Yuanji, the third elder. Therefore, it is very likely that he just wanted to teach Li Shimin some lessons at this banquet, so that he would not be stupid enough to let himself fall into a situation where he could not be worth the loss. To sum up, Li Jiancheng had some scruples, so that the poisonous wine that Li Shimin drank was not enough to cause death. But Li Jiancheng did not expect that his one thought had led to his own death.
