The famous "sword dance" in the Tang Dynasty (referring to the vigorous and unrestrained dance style)-"sword" is a vigorous and magnificent dance. Du Fu's poem "Watching Gong Sundaniang's Disciples Dance Sword" describes the scene of Gong Sundaniang performing "sword dancing" in the folk, which is soul-stirring: it looks like Hou Yi shooting nine suns, and it looks like a group of immortals dancing in Lapras. Intense places, such as lightning; Quiet as a river and sea.
The Gongsun family was called into the palace to perform, and their skills were superb. Yichun Academy and Liyuan, where experts gathered, were unparalleled. "Poems of Jinyang Gate" describes the grand performance in the holiday palace, and there is a sentence of "palace magic". Zheng Yu, the author of this poem, pointed out: "There was a sword dance in Gong Sundaniang, and the number at that time was magnificent."
