1, Wei Zhi made psychological preparations for Li Shimin in advance.
Wei Zhi's exhortation to Li Shimin is not only a foolish suggestion, but usually paves the way for Li Shimin in advance. For example, he would tell Li Shimin that I want to be a good minister in Wei Zhi's life. A good minister can get along well with the emperor because he met a good emperor. Such a tall hat makes Li Shimin very comfortable.
2. Wei Zhi often defeats Li Shimin with the wind of Yao and Shun.
When Wei Zhi made comments, he also annoyed Li Shimin many times. But whenever I Li See Shimin is angry, he will move out of Yao and Shun's modesty, which is actually an indirect knock on Li Shimin. If you want to be a good emperor, you should learn from them. Most ancient emperors hoped to get a general evaluation from later generations.
Wei Zhi got the support of her eldest grandson.
Empress Grandson has a reputation as a wise queen of past dynasties, and has always appreciated Wei Zhi's integrity. Therefore, whenever I am annoyed by Wei Zhi's suggestion in Li See, I will make Li Shimin understand in various ways that you are a wise monarch and there will be a direct minister like Wei Zhi. It is precisely because the queen's eldest grandson has always supported behind her back that Wei Zhengcai has always insisted on speaking out.
