Li Shimin can successfully launch the Xuanwumen Revolution, and it is inseparable from the help of one person, he is Wei Chigong. Wei Chigong was strong in martial arts, dark-skinned, fierce-looking, straightforward and reckless in character, loyal to Li Shimin, and deeply liked by Li Shimin. When Li Shimin was fighting in Jiangshan, Wei Chigong had always followed Li Shimin and was loyal to him, and Wei Chigong had also made a lot of meritorious contributions, and at the same time, at the time of Li Jiancheng's assassination of Li Shimin, he rushed to the horse and saved Li Shimin's life, so Li Shimin trusted Wei Chigong even more, and later when Li Shimin launched the Xuanwumen Rebellion, Wei Chigong also fully supported it.
When Li Shimin launched the "Xuanwumen Rebellion", Wei Chigong took the lead, he closed the city gate and locked the prince's reinforcements outside the city, which bought time for Li Shimin to kill the prince and Li Yuanji. Wei Chigong then strangled Li Yuanji with his own hands, and at the last moment, forced Tang Gaozu Li Yuan to abdicate, and after the coup was successful, Li Shimin ascended the throne. Speaking of Zhen Wei Chi Gong had "merit from the dragon", coupled with the fact that he later attacked the Turks in the east and conquered Goguryeo to establish the Geshi qigong, he was given the title of Duke of Wu by Emperor Taizong, and he received the title of Grand General of the Right Wu Marquis, which was the same for a while, and at this time his status and achievements were dumped on Qin Qiong Eighteen Streets.
After Li Shimin ascended the throne and became emperor, he did not treat Wei Chigong badly, and he was awarded the title of Duke of Wu for his merits and promoted to the rank of Grand General of the Marquis of Right Wu, which was already quite good. Later, Li Shimin often couldn't sleep, and Wei Chigong and Qin Shubao went to stand outside the door to guard Li Shimin, thus becoming the door god of our current New Year, which can also be regarded as a corresponding harvest. Wei Chigong was a military general, and his strategy was not as good as Fang Xuanling and Du Ruyi, but his position during Li Shimin's period was quite unusual, which led to the fact that sometimes Wei Chigong would also be proud of his achievements and rely on the old and sell the old.
After Li Shimin ascended to the throne, he was made the Duke of Eguo, first of all, there will certainly be all kinds of figures in a country, because Wei Chigong has a straight temperament and is proud of his achievements, when he sees Fang Xuanling, Du Ruqian, Changsun Wujie, and others, he often ridicules them in person, discusses their length and shortcomings, and sometimes even argues fiercely above the court, so the relationship with these people gradually deteriorates, and since then Wei Chigong has rarely appeared in the court, and he rarely goes out.
