Literally, the lyrics of Bai Diao have formed a unique poetic rhythm of this nation, commonly known as "3715" style, that is, each lyric consists of three seven sentences and one five sentences (most of Bai Yun basically follows this rhythm). Yang Nai, a Bai poet in Ming Dynasty, wrote a long poem "Ci Ji Hua Shan Yong Cang Er Jing" in Bai language, which was written in this way, so it is also called "Mountain Flower Style". The vast majority of Bai folk songs are short songs with seven or eight sentences, which are divided into two sections. The first section usually begins with three words and one rhyme, followed by two seven sentences and one five sentences. Xiaque consists of three seven-character poems and one five-character poem, and the upper and lower que constitute a complete poem.
