Does anyone know that poem refers to the regret that parents did not support their parents when they were alive and did not support them until after they died? thank you

The tree wants to keep quiet, but the wind will not stop; My son wants to serve his parents when they are old, but they are gone.

This is a warning to filial sons from the opposite side, explaining that filial piety should be timely. When parents are alive, they can't wait until the day their parents die.

Later, the metaphor of "the tree wants to be quiet but the wind will not stop" is an objective law that does not depend on people's subjective wishes. It is also used to indicate that one party wants to stop doing something, but the other party won't let it stop. Doing something here generally means injustice.
