Bo Yu Qi Zhang

Bo Yu was reportedly a man with great filial piety towards his parents in ancient China. One day， he made a mistake and his mother beat him with her walking stick. Bo Yu cried. His mother felt strange about this and asked him why he cried.

Bo Yu answered： “When I was a kid， you beat me and I cried because of the pain I felt. Now I am a grown-up and you became old so you can not pain me by beating me. But I still felt guilty because I still caused you to worry about me in spite of your age. Thats why I cried.”endprint
