Before Tet holiday, there are a lot of things going on. 
People from places go back to their hometown, back to their family. They together clean up the house, decorate it with flowers, plants and other kinds of decorations. Then parties are held everywhere to celebrate the end of the year. Some people go to the pagodas to pray and complete the ritual ceremonies of the year. 

Food preparation is also conducted at this time of the year. Feasts will be prepared and presented to the altar. 

Overall, this is a very busy time of many people in the year. I enjoy the atmosphere at lot.

The preparation for Tet often begins before one or two weeks. First, people frequently spend a few days cleaning their houses, polishing furnishings and bronze incense burner, or even repainting the walls. They want everything in the houses must be clean and clear to get good lucks in New Year and get rid of bad ones in the old year. Moreover, houses are garnished with colorful lights and parallel sentences. Besides, many Vietnamese prepare for Tet by cooking special holiday foods, such as square rice cake, dried young bamboo soup and pickle. Furthermore, they also buy other kinds of food like cakes, candies, jam. These are extremely delicious and contain culinary culture in Vietnam.
