　　【参考范文】st families have one child. If such children were not filial, we couldn't imagine how disappointed their parents would be with nobody else to turn to when they are old. Next, children are unique to their parents, whose expectations do good to them. Even if there exist some disagreements between them sometimes, children can't make their parents in a bad mood. Finally, children should be grateful to their parents. But for their love and care, any child wouldn't become a healthy happy and useful person.

　　In short, children ought to respect and comfort their parents. As is known, filial piety, which is part of traditional Chinese culture, deserves to be preserved.
