Offer sacrifices to Da Yu
White Dew is a time for people in the Taihu Lake area of East China to offer sacrifices to Da Yu, a hero who tamed floods by regulating rivers and watercourses. On the first day of White Dew, people also hold sacrificial rites for Da Yu on the eighth day of the first lunar month, on Tomb-sweeping Day, and on the seventh day of the seventh lunar month.
