Introduction of Shangsi Festival

According to historical research, the origin of Shangsi Festival can be traced back to the Zhou Dynasty. Witchcraft superstition prevailed in the Zhou Dynasty. Every year on the "Shangsi" day in March (the "Shangsi" day in the first half of the year), witches hold a ceremony for people to eliminate disasters and diseases by the river, which is called "Zan". It means to remove evil spirits and make them clean; Hair means cleaning the body and removing filth. The ancients thought that water was the purest thing. If you "wash your body" at the water's edge, you can eliminate disasters and ensure peace for one year. Because the specific date of the fourth day of the third lunar month is not fixed every year, in order to facilitate memory and unity, the fourth day of the third lunar month was designated as the "fourth day" from the Han Dynasty, and in the Wei and Jin Dynasties, the third day of March was clearly designated as the Shangsi Festival.
