On the eve of the Xuanwu Gate Rebellion, Li Shimin asked Weichi Gong to kill Fang and Du Ruhui. Why did he do it?

On the eve of the Xuanwu Gate Rebellion, Fang and Du Ruhui pretended not to accept the invitation. Thinking that they would support themselves, they asked Weichi Gong to kill Fang and Du Ruhui. Fang and Du Ruhui followed Li Shimin long ago and have always been Li Shimin's right-hand man. After being invited, Fang and Du Ruhui also thought about many issues. They were afraid that Li Shimin had not made up his mind, so they used this method to stimulate Li Shimin and make him determined to launch a coup.

Since Fang and Du Ruhui followed, they have been regarded as wise men to save the world. They also spared no effort to help Li Shimin and made many strategic plans for Li Shimin. Li Shiming was able to become an emperor through the ages without the help of these two famous ministers. Without them, Li Shimin might not be king.

In order to weaken the strength, Li suggested that Fang and Du Ruhui should be transferred from there, and agreed to this practice. In the past, Li Shimin would consult with Du Ruhui before making any decision. Now, without them, Li Shimin has no bottom.

On the eve of the change of Xuanwu Gate, Li Shimin invited them back to discuss something important. However, Li Shimin was rejected by the reply he received. Both Du Ruhui and Fang wrote back that they didn't want to participate in this matter. Li Shimin was so angry that Weichi Gong wanted to kill them both. When Fang and Du Ruhui heard about it, they knew that they had made up their minds to launch a coup, so they went to Shimin with Weichi Gong.
