What does this bamboo stand for?

Bamboo is one of the four gentlemen in flowers and one of the three friends of the poor.

The bamboo pole is elegant, upright and has clear joints. Paying attention to honesty is the tradition of China people. "Qi" is a noble spirit and a spirit; "Festival" is a kind of personality; "Integrity" means that people should have noble spiritual sentiments, not flatter powerful people, and still adhere to their integrity in times of crisis. "Jade can be broken without changing its whiteness, and bamboo can be burned without destroying its knots."

"There is a knot when it is not unearthed, and Lingyun is still modest." Because of its hollow knots, bamboo can be self-sustaining, and the culm is straight and not bent, and it is rising step by step.
