Filial piety is based on the fundamental bond between parent and child. Confucius believed that filial piety was the root of humanity. This Chinese internet cartoon illustrates the idea of filial piety. As the mother lovingly washes the feet of the small child, so the child, when he is grown-up, lovingly washes the feet of his elderly mother, remembering the care he received in his childhood. Filial piety is the duty of respecting and caring for one's parents and grandparents, reciprocating the love and care shown one as a child.
