On April 18, the Hanfu Culture Society of Changzhou Folk Literature and Art Association held a celebration for Shangsi Festival in the Jinyuan Garden. A group of young people wearing hanfu, the traditional clothing of the Han ethnic group, gathered at the garden and participated in traditional Shangsi Festival activities.

Shangsi Festival, also known as the Double Third Festival, is an ancient Chinese festival celebrated on the third day of the third lunar month, which falls on April 14 this year. It is also a day considered to be the possible birthday of Huang Di, the Yellow Emperor. A well-known phrase goes, "San yue san, Xuan Yuan sheng", meaning, "On the third day of the third month, the Xuan Yuan (Yellow Emperor) was born."

In 2018, the Communist Youth League's Central Committee set the third day of the third lunar month as China Huafu Day (Chinese National Costume Day), as a way to advocate the beauty of traditional Chinese clothes.
