Don’t drink. The Spring Society in the Song Dynasty is one of the oldest traditional Chinese folk festivals. During the Spring Society, people drink She wine instead of calamus wine. They only drink calamus wine during the Dragon Boat Festival. The time of Spring Society is the fifth Wu day after the beginning of spring, around the vernal equinox. However, among Chinese people, it is also said that it is the second day of February, the eighth day of February, the twelfth day of February, and the fifteenth day of February.
