The concept of "family" is extremely important to the Chinese people. It is developed in thousands of years of Chinese culture and tradition. Large families are especially highly regarded. In the old days, it was not uncommon to find four generations of family living under the same roof. In these days, it is still possible to find at least three generations living together. Many people continue to live with their parents after marriage. This enables them to care for their elders. Likewise, grandparents can help care for their grandchildren. Respect for the aged and love for young children are regarded as traditional virtues of the Chinese people. A happy and harmonious family is greatly respected and admired. In recent years, more and more young married couples have chosen to live apart from their parents. However, they still frequently visit their parents, especially during important festivals such as the Mid-autumn Festival and the Spring Festival.
