『叄』 英語翻譯
American-style family structure is relatively simple: parents and children as a core family. Once the children get married, they move away to live independently. Parents no longer have an obligation to support their children. This approach to young people gives them great freedom and power to develop their independent living, but also alienates the relationship between relatives. Chinese style family structure is more complex, traditional happy family is four generations. In such families, children help take care of elderly, children grow up to help the elderly, family members depend on each other, help one another, everyone has a close family relationship. However, this way of life is not concive to nurturing young people's independence.
