Bamboo: Grow straighter and taller! So we should constantly sum up ourselves!
Being a man is like the ears of grain in the autumn harvest. The more successful you are, the lower your head and the less arrogant you are.
Being a man must be as humble as bamboo. Another poem is well said: I insist that Qingshan will not relax and let the east, west, north and south wind. Metaphor is honest, strong and determined.
