The best quotes about filial piety and respect for relatives include:

“Filial piety is the first of all good deeds, and the source of all evils is sexual immorality. If you always have benevolence and filial piety, then no one in the world can bear to do anything that is not allowed. Therefore, filial piety is at the forefront of all actions; if you have any evil thoughts, it will be easy to do anything you don’t want to do in life. Therefore, adultery is the first of all evils.”

The most important thing for a filial son is to respect his relatives. ——Mencius.

The virtuous and the unworthy cannot be separated. If fate cannot be changed, if good and evil cannot be moved. ——"Lu's Spring and Autumn Annals".

A filial son does not flatter his relatives, and a loyal minister does not flatter his king. This is the prosperity of ministers. ——Zhuangzi.
