Vietnamese traditions are well preserved and passed down through generations thanks to the Vietnamese people's love for their country. They have a long history of fighting against foreign invaders, such as China and France. This has made them very protective of their culture and traditions.
One of the most important traditions is Tet, the Lunar New Year. It takes place in January or February. The whole country stops working for a week to celebrate. People visit their families and give each other lucky money in red envelopes. They also clean their houses to get rid of bad luck from the old year. There are many delicious foods to eat at Tet, such as "banh chung", which is sticky rice with pork inside, wrapped in “dong” leaves.
Another important tradition is ancestor worship. Vietnamese people believe that when someone dies, their soul lives on and can protect the family. They have an altar in their house where they put pictures of their ancestors. Every day, they light incense and offer food and drink to their ancestors. During Tet, they invite their ancestors' spirits to join the celebrations. They also clean and decorate their ancestors' graves and bring them food and flowers.
