It is generally believed that the singing in the temples in the Tang Dynasty marked the formal formation of rap music. After the Song Dynasty, rap music developed rapidly, with the emergence of Tao Zhen, Ya Ci, Drum Ci, Singing Earnings and other genres, especially Zhugong Tune, which had made great achievements in the Jin and Yuan Dynasties. There are 4 tunes used in Dong Jieyuan's The Legend of the West Chamber, which shows the prevalence of palace tunes.
