Tet holiday is celebrated on the first day of the Lunar New Year. Some weeks before the New Year, the Vietnamese clean their house and paint the walls. New clothes are bought for the occasion. One or two days before the festival, people make Banh Chung, which is the traditional cake, and other goodies. On the New Year‘s Eve, the whole family gets together for a reunion dinner. Every member of the family should be present during the dinner in which many different kinds of dishes are served. On the New Year morning, the young members of the family pay their respects to the elders. In return they receive lucky money wrapped in red tiny envelopes. Then people go to visit their neighbors, friends and relatives.
