Tết is also an occasion for pilgrims and family reunions. During Tết, Vietnamese visit their relatives and temples, forgetting about the troubles of the past year and hoping for a better upcoming year. They consider Tết to be the first day of spring and the festival is often called Hội xuân (spring festival).

Before New Year's Eve

This period begins one or two weeks before the actual celebration. The general atmosphere leading up to Tết is in the bustle of shopping, decorating the home, cooking traditional Tết food and waiting for relatives to return home. People try to pay off their debts in advance so that they can be debt-free on Tết. Parents buy new clothes for their children so that the children can wear them when Tết arrives. Because a lot of commercial activity will cease during the celebrations, people try to stock up on supplies as much as possible.

The New Year

The first day of Tết is reserved for the nuclear family. Children receive a red envelope containing money from their elders. This tradition is called mừng tuổi (happy new age) in the north and lì xì in the south. Usually, children wear their new clothes and give their elders the traditional Tết greetings before receiving the money. Since the Vietnamese believe that the first visitor a family receives in the year determines their fortune for the entire year, people never enter any house on the first day without being invited first. The act of being the first person to enter a house on Tết is called xông đất, xông nhà or đạp đất, which is one of the most important rituals during Tết. According to Vietnamese tradition, if good things come to the family on the first day of the lunar New Year, the entire following year will also be full of blessings. Usually, a person of good temper, morality and success will be the lucky sign for the host family and be invited first into the house.

However, just to be safe, the owner of the house will leave the house a few minutes before midnight and come back just as the clock strikes midnight to prevent anyone else entering the house first who might potentially bring any unfortunate events in the new year to the household.

Sweeping during Tết is taboo or xui (unlucky), since it symbolizes sweeping the luck away. It is also taboo for anyone who experienced a recent loss of a family member to visit anyone else during Tết.

During subsequent days, people visit relatives and friends. Traditionally but not strictly, the second day of Tết is usually reserved for friends, while the third day is for teachers. Local Buddhist temples are popular spots as people like to give donations and to get their fortunes told during Tết. Children are free to spend their new money on toys or on gambling games such as bầu cua cá cọp, which can be found in the streets. Prosperous families can pay for dragon dancers to perform at their house. There are also public performances for everyone to watch.

Traditionally, each family displays cây nêu, an artificial New Year Tree consisting of a bamboo pole 5 to 6 m long. The top end is usually decorated with many objects, depending on the locality, including good luck charms, origami fish, cactus branches, etc.

At Tết every house is usually decorated by hoa mai – Ochna integerrima (in the central and southern parts of Vietnam) or hoa đào – peach flower (in the northern part of Vietnam) or hoa ban (in mountain areas). In the north, some people (especially the elite in the past) also decorate their house with a Prunus mume tree (also called mai in Vietnamese). In the north or central, the kumquat tree is a popular decoration for the living room during Tết. Its many fruits symbolize the fertility and fruitfulness that the family hopes for in the coming year.

Vietnamese people also decorate their homes with bonsai and flower plants such as chrysanthemum (hoa cúc), marigold (vạn thọ) symbolizing longevity, mào gà in Southern Vietnam and paperwhite flower (thủy tiên), lavender (viôlét), hoa bướm in Northern Vietnam. In the past, there was a tradition that old people tried to make their paperwhite flowers blossom right the watch-night time. They also hung up Dong Ho Paintings and thư pháp (calligraphy pictures).

The traditional greetings are "chúc mừng năm mới" and "cung chúc tân xuân" (Happy New Year). People also wish each other prosperity and luck. Common wishes for Tết include:

Live up to 100 years: used by children for elders. Traditionally, everyone is one year older on Tết, so children would wish their grandparents health and longevity in exchange for mừng tuổi or lì xì

      Security, good health, and prosperity

May a myriad things go according to your will

Plenty of health

 Congratulations and be prosperous

May money flow in like water

In Vietnam, to celebrate Tết is to ăn Tết, literally meaning "Tết eating", showing the importance of food in its celebration. Some of the food is also eaten year-round, while other dishes are only eaten during Tết. Also, some of the food is vegetarian since it is believed to be good luck to eat vegetarian on Tết. Some traditional food on Tết are:

Bánh chưng and bánh dầy: essentially tightly packed sticky rice with meat or bean fillings wrapped in banana leaves. Bánh chưng (rectangular) and bánh giầy (circular) are symbolically connected with Tết and are essential in any Tết celebration. Preparation is time-consuming, and can take days to cook. The story of their origins and their connection with Tết is often recounted to children while cooking them overnight.

Hạt Dưa: roasted watermelon seeds, also eaten during Tết.

Dưa Hành : pickled onion and pickled cabbage.

Củ Kiệu: pickled small leeks.

Mứt: These dried candied fruits are rarely eaten at any time besides Tết.

Cầu Dừa Đủ Xoài - In southern Vietnam, popular fruits used for offerings at the family altar in fruit arranging art are the custard-apple/sugar-apple/soursop (mãng cầu), coconut (dừa), papaya (đu đủ), and mango (xoài), since they sound like "cầu vừa đủ xài" ([We] pray for enough [money] to spend) in the southern dialect of Vietnamese.

Thịt Kho Nước Dừa Meaning "Meat Stewed in Coconut Juice", it is a traditional dish of pork and medium boiled eggs stewed in a broth-like sauce made of young coconut juice and nuoc mam. It is often eaten with pickled bean sprouts and chives, and white rice.

People are delighted to enjoy exciting games during Tết: bầu cua, cờ tướng, ném còn, chọi trâu, đá gà, marshmallow toss, etc...They also participate in some competitions presenting their knowledge, strength and aestheticism such as: bird competition and ngâm thơ competition.

Dos

One should give people lucky presents to enhance the relationship between themselves and others: new clothes, peach branches (for expelling evil), cocks (wishing for good manners), new rice (wishing for being well-fed), rice wine in a gourd (wishing for a rich and comfortable life), bánh chưng (or bánh tét) and bánh dày which symbolize sky and earth (for worshipping the ancestors), red things (red symbolizes happiness, luckiness, advantages) like watermelon, dogs (the bark – gâu gâu – sounds like the word giàu - richness in Vietnamese language), medicated oil (dầu in Vietnamese, also sounds similar to giàu).

One should give lucky Dong Ho Paintings such as: "Gà đàn" (wishing for having many children), or "Vinh hoa", but should not give unlucky Dong Ho paintings like "Đánh ghen" related to legal proceedings.

One should buy a lot of water for Tết, because people wish for money to flow like water currents in a stream (proverb: "Tiền vô như nước").

One should sprinkle lime powder around the house to expel evil.

One should return all things borrowed, and pay debts before Tết.

Don'ts

One shouldn't say or do bad things during Tết.

One shouldn't hurt or kill animals or plants but should set them free. The reason for this originates from Buddhism's causality.

One shouldn't sweep the house or empty out the rubbish to avoid luck and benefits going with it, especially on the first day of the new year. One shouldn't let the broom in confusion if people don't want it to be stolen.

One shouldn't give these presents to others: clock or watch (the recipient's time is going to pass), cats (mèo in Vietnamese language pronounced like nghèo, poverty), medicine (the receiver will get ill), cuttle fish (its ink is black, an unlucky colour), writing ink (for the same reason), scissors or knives (they bring incompatibility).

One shouldn't have duck meat because it brings unluckiness.

One shouldn't have shrimp in case one would move backwards like shrimp, in other words, one would not succeed.

One shouldn't buy or wear white clothes because white is the colour of funerals in Vietnam.

One shouldn't let the rice-hulling mill go empty because it symbolizes failed crops.

One shouldn't refuse anything others give or wish you during Tết.
