"A very popular belief among Vietnamese is the custom of the ancestor cult. In every household, an ancestor altar is installed in the most solemn location. Vietnamese believe that the soul of a dead person, even if he/she was dead for many generations, still rests along with their descendants on earth. The dead and dead people still have spiritual communion with their dead relatives. On the anniversary of an ancestor's death, descendants and relatives unite and prepare a feast to honor the dead people and to ask for health and happiness for themselves. From generation to generation, an ancestor worshiping custom has been religiously preserved. There are some small variations in those customs among the many Vietnamese. The last day of every lunar year, an announcing cult is performed to invite the dead forefathers to return home to celebrate Tet holidays with their families. During the last days before Tet, all family members visit their ancestors' graves; they clean and decorate the graves, in the same manner."
