China's family values are related to its cultural traditions. Harmonious extended families used to be very enviable. It was not uncommon in the past for four generations of a family to live under the same roof. According to the tradition, many young people continued to live with their parents after marriage. Today, that tradition is changing. As housing conditions improve, more and more young couples are opting to live apart from their parents. But the connections between them still remain strong. Many old people still help to look after their grandchildren. And young couples take time to visit their parents, especially during important festivals such as the Spring Festival and the Mid-Autumn Festival.
