bạn có chọn tết là ngày lễ bạn muốn nói tới
Ex: There are many festivals in Vietnam, but Tet is the festival I like best. Because in Tet, I can wear new clothes and have some lucky money from my grandparents. Also in Tet ,I don't need to go to school instead I can travel to some special places with my family. In my city, they fire fireworks every Tet occasions. But the most important that I can eat alots of food I like.
