This festival can be traced back to the end of the Spring and Autumn Period. It is the most important festival in ancient times. People go to the water to bathe together, which is called "Zan Zan". Since then, it has added sacrificial feasts and meandering water. In ancient times, the first third day in early March was marked by "dry branches", which was called "Shangsi". After Wei and Jin Dynasties, the festival was changed to the third day of March, so it was also called Chongsan or March 3.
Later generations followed it, and it became a festival of drinking by the water and having a spring outing in the suburbs. The traditional Shangsi Festival is also a baby day, that is, "Spring Bath Day", also known as Daughter's Day. After the Song Dynasty, Shangsi Festival, like Huachao Festival, was gradually forgotten by people.
Today, the third day of March is still a grand and grand festival in some ethnic minority areas in the southwest of China. From the Water-splashing Festival held in Dali, Yunnan Province on March 3 every year, we can vaguely see the shadow of the ancient festival. The "March 3rd" festival is still popular among ethnic minorities such as Zhuang, Dong, Buyi, Yao, Li, She and Tu.
