Is it mother's filial piety or father's filial piety?

Both will do. The last sentence is "Brothers and Friends", which comes from "Gentleman Drinking Songs". Another "Historical Records" cloud: the righteousness of the father, the grace of the mother, the friend of the brother, the respect of the younger brother, and the filial piety of the son. It is said that it is the father's responsibility to educate the children of ancient gentry. Who knows that in modern times, mothers are literate and spend more time educating their children than fathers. The happy life of mothers is to hope that they can be kind to their children and not jump around with them at home. hahaha. Except for the first sentence, everything else is nonsense, and there is only one point.
