It is universally accepted that filial duty (孝道) is a important virtue in China. It means respecting and caring parents and the elderly. Take my parents as an example, after my grandma passed away last year, my parents spent much more time chat with my grandpa, going out for a walk with him and cooking him delicious food. At first, my grandpa seemed to be happy. And as time went by, he became uneasy, because he was not used to leading so a comfortable life. Therefore, my parents encouraged him to attend some activity in our community. They also encouraged her to go to a drawing class in a school for the old, which gave my grandpa a great sense of achievement. He becomes very happy again.
My parents set a good example to me. In my opinion, the real filial duty is giving the old that they really need.
