 In the Six Dynasties period, between the end of the Han dynasty and the beginning of the Sui dynasty, there were pronounced influences from Central Asia on Chinese music and dance.Musical instruments such as the pear-shaped "pipa" and dances such as the lion dance may have been introduced in this period via Central Asia.The music and dance of Kucha became popular, as did that of Western Liang (in modern Gansu province), which may be an assimilation of styles from Han and other non-Han people.
