How were martial arts and dance innovated in Panshidong?

In the play "Pansi Cave", martial arts is a focus, and almost all the martial arts programs of Peking Opera are performed. Some difficult acrobatic open fights are very attractive to young audiences. The dances in Pansi Cave have many new creations, such as the introduction of Xinjiang dance and social dance to show the relationship between Piggy and the female demons. Combined with the function of the spider spirit's silk rope, a ribbon drill similar to that in gymnastics was invoked. Piggy is also sawed in two on stage in public, another reference to magic in theater.
