1, Tang Taizong Li Shimin's poem "To Xiao Yu" means that only after the strong wind blows wildly can you know which grass is tough; Only after experiencing danger and turmoil can we know who is a loyal minister and who is a good soldier.
In the later period of the rule, his son Li He waged a desperate struggle for the throne. In this struggle, Xiao Li stood firmly on Li Shimin's side and finally helped him win the throne. These two poems, "A gust of wind can tell the strength of grass, and a shake of the board can tell the sincerity of the minister", express Li Shimin's high praise and affirmation of Xiao Li in a bi xing way, and are also full of gratitude.

That's all I've brought you about what it means to know a sincere priest in the high wind.
