This paper presents some new ideas: First,the "back seat" in Dunhuang Manuscripts means those accompanists sitting in the back of the bank.Second,"head" in the sentence "head as the leader" in Dunhuang dance manuscripts corresponds to "dui-tou"(the first one of the team) of the grand dance show in the Tang and Song Dynasties.Third,the use of the suggestive word "liao" in Dunhuang Manuscripts is consistent with the texts of Vulgar Talk and Grand Dance Shows of the southern Song Dynasty and the Poetic Drama of the Yuan Dynasty,similar to the texts of court dance show of the northern Song dynasty,which used "qi" instead of "le." Finally,Zhong Kui in local religious ceremony at Dunhuang may be acted by a good dance musician in the music bank.
