Also known as "Pingdiao Sanxian" and "Pingdiao Qingqiang", it is one of the rare types of music in Shandong. In the late Qing Dynasty, it was passed from Qingzhou Wu Daluo to Jinan, and then from his apprentice Lihua to Jining, and taught to Cheng Sini, who then passed it on to Wang Fengyu and Wang Fengxian, and then to Caozhou and Puyang respectively. Around 1900, there were performances in Xuzhou. Later, because its melody was too euphemistic and difficult to sing in a big book, it was gradually replaced by Qinshu and Zhuizi. At first, it was mostly sung by female artists and blind artists. When singing, the hands hold the pipa, the feet step on the "Yaojin" (i.e. iron ruler and gold medal, which were later changed to hand-held), and the three-string pipa accompaniment. The singing style is a seven-tone palace mode, and the five board styles of "Pingtou", "Xiaoqingqiang", "Chuanzi", "Liuzi" and "Caiqiang" are derived from "Daqingqiang" and "Quliuzi". The traditional bibliography only includes novellas such as The Legend of the White Snake, The Story of the Bees, and The Oiran, as well as more than 60 songs based on The Dream of the Red Chamber and folk tales.
