"Emperor Taizong loves him" can be found in The Romance of Sui and Tang Dynasties written by Liu Quan in the Tang Dynasty. It tells the story of Emperor Taizong Li Shimin and the famous minister Wei Zhi. Emperor Taizong likes to play with birds. One day, he got a beautiful harrier, handsome in appearance and beautiful in coat color. He likes it very much and enjoys it in the palm of his hand. At this time, Wei Zhi came from a distance, and Taizong quickly hid the kite in his arms; After Wei Zhi found out, he came to tell Emperor Taizong something nearby. He took the opportunity to tell Emperor Taizong about the fact that ancient emperors lost their country and their lives because of their desire for ease and enjoyment, and urged "Ming Jun" to take this as a warning. Wei Zhi kept talking and didn't want to stop. The harrier was suffocating in the arms of Emperor Taizong, which was a pity for Emperor Taizong. But he always respects Wei Zhi and doesn't want to interrupt him. Wei Zhi chattered until the harrier died in Taizong's arms.
Political atmosphere-rest and recuperation
The political system in the early Tang Dynasty was characterized by democracy under imperial power. So there is a certain democratic atmosphere.
