Dong, the original Tang and Song Dynasties, was later used as a epigraph. It was originally used to read Buddha in caves. There is this tune in Dunhuang Quzi, but it is different from the style of the word written by Song people. There are two styles: alto and long tone. The music collection consists of three tones: Zhong Lu, Lu Xian and General Implication, and the sentences read differently. Eighty-three words with three rhymes. Dong Xian Ge Ling written by Dongpo Yuefu is often regarded as the standard. The syllables are very comfortable and extremely swaying. The second sentence of the former part is the sentence of the former part and the last four sentences, and the last eight-character sentence of the latter part is the end of seven words plus a disyllabic word, followed by four words plus two sentences plus a disyllabic word. The second sentence of the last part also uses the syntax of upper two and lower three, and one or two interlayers are added to the whole film, which is slightly different.
