Why didn t Li Shimin kill the founding heroes?

It's not that they don't kill, but let them no longer participate in court politics, especially military generals, like Li Xiaogong, Wei Chigong, Li Jing in his later years are closed doors and do not communicate with people (these three are the top three among the generals of Lingyan Pavilion), when Tang Taizong conquered Goryeo, in order to prevent them from making moves in the rear, he took them all (Li Xiaogong is dead), Li Jing was sick and didn't want to go, Tang Taizong compared him to Sima Yi and forced him to go, Tang Taizong deposed Li Ji before he died, and told the prince Li Zhi to kill him if he didn't go.

Li Shimin is different from Liu Bang and Zhu Yuanzhang, their family itself is a nobleman, and the way they play in the circle cannot be the same as Liu Bang and Zhu Yuanzhang, for example, Yang Guang is Li Shimin's father-in-law and cousin, and openly killing the old Sui people is easy to cause turmoil!

At the beginning of the Tang Dynasty, internal and external troubles were still serious, with natural disasters inside, Turkic and Feng Ang outside. So you can't kill Xungui, after all, someone has to lead the troops to fight!

Because he himself has great ability, he shocks people, and there is no need to kill.

Because he has been at war ......How old is Su Dingfang, he has been brought to the Goguryeo battlefield ......And he is younger than all the generals
