On the day before the festival， parents  buy new clothes for their children. Children also buy presents for their parents. On the Spring Festival Eve（除夕）， all the family members come back to their hometown. This is a happy moment. Some sing and dance， some play cards and others get the dinner ready. When they enjoy the meal， they give each other the best wishes for the coming year. They all have a good time.
