Book of Rites
Aside from the formal and ritual dances, popular and folk dances are also mentioned in ancient texts. In the "Book of Rites", it is recorded that Marquis Wen of Wei expressed concerns about falling asleep during the measured and stately court performances and preferred the popular new music and dances of Wey and Zheng; however, his Confucian advisor condemned these as decadent and disorderly.
