The Double Third Festival, also ancient Shangsi Festival is an ancient Chinese festival. It comes on the third day of the third lunar month, so It's not on the same day every year. The day is said to be the birthday of Yellow Emperor (Huangdi). It didn't have a fixed date until the Wei and Jin dynasties(朝代).
In the Eastern Jin Dynasty, people often bath in the river on that day to wash away bad luck. Wang Xizhi wrote in his Lantingji Xu- about how people took a bath and wrote poems while drinking. In the Tang Dynasty, people enjoyed drinks and sightseeing. In the Ming and Qing dynasties, people did activities like throwing stones, going for long walks in the country and listening to music.
In modern times, people in the southern parts of China mainly celebrate the festival. For the Zhuang people in Guangxi, they can enjoy a two or three- day holiday. And it is a festival for young people to sing songs and find their true love. Bamboo dancing is another important actıvıty for them. For the Li and Miao people in Hainan, it is a day for remembering ancestors (祖先). For the Han people, it is a time to go outside to enjoy flowers and cook eggs with jicai. The Han people believe the wild vegetable and the special eggs are of great benefit to human health. In some areas, there are dragon boat races and other cultural performances to celebrate this lucky day.
All in all, the Double Third Festival is a time for people to feel nature, share traditions, and celebrate the arrival of spring with joy.
