Da'ao Haozi is popular in Lai'an Street, Nanliuji Township, Baji Township, Likou Town, Liren Township, Chuancheng Town, Sanzhuang Township, Zhangjiayu Town, Aiyuan Town, Peiyu Town and other places in Siyang County. It is included in the book "Collection of Chinese Folk Songs" (Supplement to "Jiangsu Volume"). It is a labor song sung by farmers in rural areas during the busy farming season. It was originally evolved from labor songs and has a certain musical melody and rhythm. Labor songs are folk songs that are produced and applied to labor. They have the practical function of coordinating and directing labor. In the process of labor, especially labor with strong collective cooperation, in order to unify the pace, regulate breathing, and release the pressure of body weight, workers often shout or call. These shouts and calls were gradually beautified by the working people and developed into the form of songs. From the simple and rhythmic calls in the initial labor to the song form with rich lyrics and complete tunes, the labor song reflects the wisdom and strength of the working people, and expresses the optimism and fearless heroism of the working people through the labor song. Labor songs are a kind of oral improvisation directly related to production activities. The tune is relatively simple, the rhythm is strong and powerful, with a lead and a chorus, and distinct pauses. The content is freely developed according to the characteristics of labor. Da'ao songs do not use musical instruments, and there are no specific requirements for costumes and props. In order to enhance their enthusiasm, the working people must sing with a firm and powerful momentum when singing. Because the lyrics and tunes of Da'ao songs are simple and the content is single, it is easy for people to accept them when singing, so the integrity of the music is well passed down.
