In fact, the Mid-Autumn Festival in Vietnam is the same as the Mid-Autumn Festival in China, but the Mid-Autumn Festival in Vietnam is mainly centered on children and carp, so there is a saying that the Mid-Autumn Festival in Vietnam is Children's Day, because the Mid-Autumn Festival in Vietnam is basically the happiest day for children, and parents will give their children their favorite toys and gifts, as well as all kinds of snacks and desserts. At that time, lanterns were indispensable, and these lanterns were made by parents themselves.

In fact, the Mid-Autumn Festival in Vietnam is all about children and carp, because there was a man named Gui in Vietnam at that time. In fact, Gui can imagine her as the Chang 'e of China. At that time, Gui got the fairy tree, but she didn't follow the fairy's warning and watered it with polluted water. As a result, the fairy tree flew to the Moon Palace, and because Gui pulled the fairy tree, it was taken away with her.

The carp is another legend. It is said that a carp became a sperm and harmed people everywhere. In order to save the people, Bao Gong tied a lantern with paper to suppress this carp essence. So later, children listened to Agui's story in the Mid-Autumn Festival night and went out to play with carp lanterns. The moral here is that when they grow up, they will jump into the dragon gate.

Another reason is that Mid-Autumn Festival was a rare festival for Vietnamese in the past, because most of Vietnam was farmers at that time. During the year, people at that time worked hard every day, and the Mid-Autumn Festival was just before the autumn harvest, and people were waiting for the crops to mature, so they had time to play with their children on the Mid-Autumn Festival, which was a rare leisure. Therefore, Vietnamese people at that time would also cherish the opportunity to have fun with their families. On this day, people will accompany their children, and there will also be some large-scale activities, singing and dancing to ask God to bless a good harvest.
