　　Family structure is the core of any culture. A major function of the family is to socialize new members of a culture. As children are raised in a family setting, they learn to become members of the family as well as members of the larger culture. The family provides the model for all other relationships in society. Through the observations and modeling of the behavior of other family members, children learn about the family and society including the values of the culture. Family structure and their inherent relationships and obligations are a major source of cultural difference.

　　The family is the center of most traditional Asians' lives. Many people worry about their families' welfare, reputation, and honor. Asian families are often extended, including several generations related by blood or marriage living in the same home. An Asian person's misdeeds are not blamed just on the individual but also on the family - including the dead ancestors.

　　Traditional Chinese, among many other Asians, respect their elders and feel a deep sense of duty toward them. Children repay their parents' sacrifices by being successful and supporting them in old age. This is accepted as a natural part of life in China. In contrast, taking care of aged parents is often viewed as tremendous burden in the United States, where aging and family support are not honored highly.

　　The Vietnamese (越南的) family consists of people currently alive as well as the spirits of the dead and of the as­yet unborn. Any decisions or actions are done from family considerations, not individualdesires. People's behavior is judged on whether it brings shame or pride to the family. Vietnamese children are trained to rely on their families, to honor elderly people, and to fear foreigners. Many Vietnamese think that their actions in this life will influence their status in the next life.

Fathers in traditional Japanese families are typically strict and distant. Japanese college students in one study said they would tell their fathers just about as much as they would tell a total stranger. The emotional and communication barrier between children and fathers in Japan appears very strong after children have reached a certain age.
