On December 30 every year, according to traditional Tet customs, Vietnamese families will prepare offerings and trays of rice to invite grandparents and ancestors to celebrate Tet with the family. Items, fruits, and candies will be placed on the ancestral altar for 3 days. After 3 days, families will prepare a sumptuous meal to say goodbye to grandparents and ancestors. This is called the golden ceremony, also known as the New Year's thanksgiving ceremony. The Golden Ceremony also means welcoming wealth, luck, and prosperity to the family, giving the family a happy and prosperous new year.
