During the Persian New Year of Newruz, a lion dance used to be performed by young boys, some of them naked it seems, who were sprinkled with cold water. They were thus supposed to drive out evil forces and the cold of the winter.
Original text: 孟康曰:「象人,若今戲蝦魚師子者也。」translation: Xiàngrén (Imitators) are like those [dancers] who act as frogs, fish, or lions today
西凉伎,假面胡人假狮子。刻木为头丝作尾,金镀眼睛银贴齿。奋迅毛衣摆双耳,如从流沙来万里。紫髯深目两胡儿,鼓舞跳粱前致辞。
