李元吉
On the dawn of 2 July 626, Prince Li Shimin and his followers arrived at the Xuanwu Gate, where they awaited the arrival of Crown Prince Li Jiancheng and Prince Li Yuanji. Chang He, a military officer stationed at Xuanwu Gate, also led his troops in support of Li Shimin on the day of the coup. As Li Jiancheng and Li Yuanji approached the Linhu Hall, they began to realize that a coup was about to unfold and immediately retreated eastward. Li Shimin rode towards his brothers and hailed them. Hereupon, Li Yuanji attempted to draw his bow to shoot his arrows at Li Shimin, but he did not manage to draw it. Li Shimin started to shoot his arrows at Li Jiancheng and killed him.
