According to the "Zi Zhi Tong Jian Kao Yi": According to the actual records of the ancestors, Jiancheng was an informal person when he was a child. He was a desolate man who was addicted to alcohol and hunting. He often traveled with his disciples, so he was called Ren Xia at that time.
Let's look at those things that Li Shimin said against him, filter out the false and retain the true. Just say the last sentence "Ren Xia", but it fully expresses his style.
"Mozi · Jing 1" explains "Ren": A scholar does what he does to the detriment of himself and to the benefit of himself.
"Mozi Jing Shuo 1" explains "Ren": to do what one hates and what one wants to do as a person.
It seems that the biggest characteristic of Ren Xia is to sacrifice one's life for righteousness.
It is impossible to record Li Jiancheng's heroic deeds in the world in historical materials, but "Da Tang Entrepreneurship and Daily Notes" still records his grace as a politician.
After a thousand years, Li Jiancheng's image is still dazzling.
Since I don't have the chance to see his experience as Ren Xia, but I still yearn for it, let's write some novels to entertain people.
