Nowadays, Vietnam has many of interesting holidays but I like Tet or the Lunar New Year best. It is a festival which occurs in late January or early February. It is the most important festival in Vietnam because it is the time for families to get together, decorate their house, make a lot of food, especially sticky rice cake. A few weeks before Tet, many families are very busy because they have to prepare a wonderful holiday for their home. They buy a lot of things and they don't forget to buy a peach tree to put in the corner of the living room. On New Year' Eve, people gather in the living room to have a special meal and after that they wait for the New Year. When New Year comes, people wish others a happy new year. The children are given lucky money from the older people,.... On the next day, the families visit their neighbors, relatives, and some temples, pagodas to wish a good year for their families. These activities are the reason why I like Tet holiday best.
