孝順 - Xiao4 Shun4 - Filial Obey — Filial Piety

This page has some stories of filial piety. Jenny knows the one with the mosquitoes and she also told me another one: A mother used to whip her son when he was bad. He would usually take the punishment quietly, but one day when she whipped him he began to cry. She asked him why, and he said “You aren’t whipping me as hard as usual. I think you are beginning to become old and weak!”
