It is not the Aquarium Festival, but the Aquarium Festival, which is a popular traditional festival in Sandu County, Guizhou Province and one of the national intangible cultural heritages. The festival of the aquarium is called "borrowing end" in water language. "Duan" means "the beginning of a year" or "New Year"; "Borrow" means "eat".

Shui people have their own calendar, and the festival usually lasts for 49 days from1February to February of the following year (from early October to mid-November of the lunar calendar), which is called the longest festival in the world. On the eve of the festival, Shui people will make new rice, brew new wine, sew new clothes, and prepare all kinds of food and fruits for ancestor worship and entertainment. On New Year's Eve, people hang bronze drums or big leather drums in the court and beat them heartily to show that they bid farewell to the old and welcome the new. Early in the morning of the first day, each family set up a fast and offered fish (the aquarium regards fish as a vegetarian dish), new glutinous rice, new rice wine, tofu, dried bamboo shoots, pumpkins, peanuts, fruits, sugar and vegetables.
