Tet is a national and family festival . It is an occasion for every Vietnamese to have a good time while thinking about the last year and the next year . At Tet , spring fairs are organized, streets and public buildings are brightly decorated and almost all shops are crowded with people shopping for Tet . At home, every is tidied, special food is cooked, offerings of food, fresh water, flowers and betel are made on the family altar with burning joss-sticks scenting the air. First-footing is made when the lucky visitor comes and children are given lucky money wrapped in a red tiny envelope. Tet is also a time for people and love. During Tet, children often behave well and friends, relatives and neighbors give each other best wishes for the new year
