Ke Mu San (Chinese: 科目三), also known as subject number three dance[1] is an internet phenomenon originating in China. Believed to have originated from a wedding dance in Guangxi, the dance involves performers executing a series of hand movements in sync with music, including quick twisting movements of the wrists while swinging their knees to the side.[citation needed] Gaining mainstream attention, restaurant chain, Haidilao also added it to their menu in November 2023.[1]
