In the summer of the ninth year of Wude (626), it was widely rumored that Turks invaded the Tang Dynasty. When the Prince was built, he recommended Wang Qi Yuanji to go to war on behalf of Wang Shimin of Qin, and Gaozu followed him. Yuanji also invited the generals of the Qin government, and Duan, and Gaozu was also indispensable. So the prince said to the king of Qi, "You have won the master of Qin, and there are tens of thousands of good soldiers. In the future, the king of Qin and I will treat you in Kunming Pool, and you will make the strong men kill you, so that the world can be settled. " The prince reported a more honest and confidential message to the king of Qin. The king of Qin was very anxious at first. On June 3, he secretly played Gaozu and said, "I didn't treat my brother badly. Now I'm going to kill my minister, as if I were avenging the king and Dou Jiande. Although I am dead, it is a pity to see a thief! " Gaozu was shocked and said, "I'll ask you tomorrow if you can arrive early." On the morning of June 4th, Shimin led Sun Chang Wuji and others to ambush in Xuanwu Gate (the north gate of Miyagi), and Zhang Jieyu had secretly learned Shimin's conversation with Gaozu, which was complete. When it is completed, Yuanji is called seeking it. Yuanji thinks that the army should be arranged to see the situation.

Shimin shouted at them at the back, and Yuanji also pulled a bow at Shimin, but he couldn't pull it out again and again in a hurry, but Shimin died with an arrow. At this moment, Wei Chijingde arrived with seventy riders and immediately shot Yuanji off the horse. Shimin himself fell off his horse and was caught by a branch and couldn't get up. Yuanji arrived, grabbed Shimin's bow and was about to strangle Shimin with a bowstring. Jingde pranced and drank, and Yuanji had to rush to Wude Hall, followed by Jingde, who shot Yuanji with an arrow. After Yuanji's death, Li Feng, the general of Yiwei motorcade, Xue Wanche, the deputy guard, and other wise men who prayed for blessings arrived at Xuanwu Gate. The confidant of Shimin, Zhang Gong, tried his best to shut himself out and refused to go in. General Yun was in charge of Xuanwu Gate in Su Weibing Village, and stood up, fought and died. The gatekeeper fought with Wanche's army for a long time, and Wanche clamored to attack Fu Qin. The soldiers were afraid, but Wei Chijingde proved it with the heads of Cheng Jian and Yuan Ji. The palace soldiers collapsed. Gaozu was boating in the inner sea pool of Xuanwu Gate when he heard the news. Shimin sent Wei Chijingde to live in the imperial guard, saying, "The King of Qin rebelled against the Prince and the King of Qi, and sent his ministers to live in the imperial guard for fear of disturbing your majesty, so he sent troops to punish him." Gaozu called Pei Ji and others and said, "I don't want to see this today. What should I do? " Xiao Yu and Chen replied: "When Heyuan Ji didn't take part in the uprising, they didn't work for the world, but the king of Qin was very successful and conspired together. The king of Qin asks for it, punishes it, and your majesty entrusts state affairs. " Gaozu nodded and said, "Good! This is also my long-cherished wish. "

Li Shimin gave all the gold and silk of the King of Qi to Wei Chijingde. Kevin·Z, the former prince who washed horses, saw that Shimin, the king of Qin, had made great achievements, and repeatedly secretly advised the prince to make contributions and get rid of Shimin. After the Xuanwu Gate incident, Li Shimin accused Wei Zhi of alienating their brothers. Wei Zhi calmly replied: "The prince has been asking for advice for a long time, and there will be no disaster today." Li Shimin appreciated his tolerance and frankness very much, but he abandoned the past and introduced it as the representative work of James.
