With the approach of the Mid-Autumn Festival on the 15th day of the eighth lunar month, the "moon cake war" and "toy war" among merchants make the festive atmosphere in various parts of Vietnam particularly strong. Unlike the Mid-Autumn Festival in China, the Vietnamese Mid-Autumn Festival focuses on children. There are all kinds of moon cakes, colorful lanterns, colorful children's toys and other holiday foods and toys with different tastes in the market, and children's faces are full of yearning for festivals. On the Mid-Autumn Festival this year, the shops selling moon cakes on the streets of Hanoi, the capital, were covered with red and green colors. Red lanterns with the words "moon cakes" were hung high in front of the shops, and various brands of moon cakes filled the shelves. During the Mid-Autumn Festival every year, lantern festivals are held all over Vietnam, and the design of lanterns is evaluated, and the winners will be rewarded. In addition, some places in Vietnam will organize lion dance activities during festivals, usually held on the evening of August 14th and 15th of the lunar calendar. During the festival, local people sit on balconies and yards, or go out with their families, put on snacks such as moon cakes and fruits, enjoy the moon and taste delicious moon cakes. The children are carrying all kinds of lanterns and playing in small groups. With the gradual improvement of Vietnamese people's living standards in recent years, the custom of the Millennium Mid-Autumn Festival has quietly changed. Many young people get together at festivals or at home, sing and dance, or go out to enjoy the moon together to enhance understanding and friendship between peers.
