What is the best topic for writing a composition about bamboo?

Bamboo is straight, not curved; It means integrity.

Although bamboo has bamboo joints, it does not stop; It's called endeavor.

Bamboo is straight outside and hollow inside, like a valley; This is an empty idea.

Bamboo can't blossom, face up; It's simple.

Bamboo is detached, independent and indomitable; It's called the drow.

Although bamboo is outstanding, it is not loose; This is a good team.

Bamboo has been handed down from generation to generation, working hard and blaming others; This is called responsibility.
