Vietnamese life revolves around the family. The Vietnamese family consists of the nuclear as well as the extended family. It is not uncommon for three generations to be living together under one roof. In Confucian tradition, the father is the head of the family and it is his responsibility to provide food, clothing and shelter and make important decisions. Within the same tradition it is believed that after someone dies their spirit lives on. Descendents will "worship" their ancestors to ensure their good favour. On the anniversary of a person's death, ceremonies are held in their memory. They are also remembered during certain lunar festivals and souls are consulted prior to important decisions or occasions such as a birth or a wedding.
