Vietnam's greatest national holiday is Tet - more properly; Tet Nguyen Dan; 鈥楩estival of the First Day' - coinciding with the first day of the lunar New Year. During the week before Tet; Vietnamese pay off their debts; clean the tombs of their ancestors; make a report on the state of the household during the past year to the Jade Emperor; and decorate their houses with sprigs of peach blossom or kumquat trees. The three days of Tet are very much a domestic affair; with all members of the family (including the spirits of the deceased) gathered under one roof. Pictures From Asia David Henley
