During the Spring and Autumn Period, Confucius was traveling abroad with his disciples when he suddenly heard a cry by the roadside. He stopped to ask why. The weeping man said, "When I was young, I was eager to learn and studied abroad. When I came back, my parents died. When I was a child, I was not there when I used to serve my parents, just like' the tree wants to be quiet but the wind will not stop'; Today, I want to support my parents. My relatives are not here. The deceased is gone, and his feelings are unforgettable, so he feels sad and cries. "
