The folk music of Zheng and Wei is the leader in this "new music" trend, and is collectively known as "The Sound of Zheng and Wei". Zheng and Wei are located in today's Henan area. They were the settlements of the Shang people in the early days. After the Zhou people destroyed the Shang people, they enfeoffed them to their relatives to manage them to prevent the merchants from causing chaos. The people of Zheng and Wei retained the tradition of frequent sacrifices by merchants, and sacrificial occasions were often places where young men and women sang, danced, and gathered to make friends. As the legacy of Shang music, "The Sound of Zheng and Wei" inherits the hearty and enthusiastic artistic characteristics of Shang music. The influence of folk music represented by Zheng Weizhiyin is expanding day by day, and it has become a camp opposed to elegant music.

Although this so-called "new music" has an older history than the elegant music known as "ancient music", they maintain a bold, fiery, unrestrained and romantic music in the unrestrained development environment of the folk. The emotional and fresh and lively style, the beautiful and touching tone and the cheerful rhythm are refreshing to people who are used to the long and dull sounds of music. Even those nobles who understood the importance of "old music" had to admit that they did like "new music". For example: Wei Wenhou during the Warring States Period once admitted that he could not help but doze off while listening to ancient music while sitting upright according to etiquette requirements, but he was tireless when listening to new music ("Book of Rites? Music Book"). King Hui of Liang also confessed: What he likes is not "the happiness of the ancestors", but "the happiness of the world" ("Mencius - King Hui of Liang").

It can be seen that the soil on which elegant music depends on has been gradually weakened by social and political changes, while folk music, which has been excluded and suppressed by the authorities since the Western Zhou Dynasty, has been affected by social turmoil and changes. It was given an opportunity for development. It is said that "on Pu Sangjian, the voices of Zheng, Wei, Song and Zhao appeared simultaneously" ("Hanshu Riyue Zhi"). With its unique appeal, "The Sound of Zheng and Wei" shook the foundation of elegant music as a tool of national governance, reflecting the irresistible trend of "new music" replacing "ancient music".
