DỊCH DÙM MÌNH ĐOẠN VĂN NÀY NHA While Christmas is considered as a big holiday in the US, in Vietnam, Tet is a special occasion for family reunions and celebrating a new year. Around the beginning of February, Tet is the officially a three – days but usually lasts throughout the first week of the Lunar year. In the weeks leading up to Tet, all homes will clean the house to get rid of bad lucks of the old year. People often put a five – fruits tray on the altars to pay their respects to the ancestors and often buy peach blossoms or kumquat trees to decorate their home. When it comes to Tet festival, it will be an omission if we do not enjoy banh chung, a traditional dish of Tet. In the last night of the old year, family members often gather together, have dinner together and look forward to the moment of a 0-hour clock, waiting for colorful fireworks all over the sky to Wish each other health and success next year. On the first day of lunar new year, people often go to grandparents, relatives and neighbors’ houses to wish them health, success and a new year full of happiness. Children often receive lucky money in a red envelope to celebrate their age from their parents or relatives. Also on these days, people often go to churches or temples to pray for the best things to their families. Tet is a very meaningful and important occasion which is always expected by every Vietnamese. Let’s forget the worries and enjoy the happy moments with your family.
