Lui is known for his virtuosity, not only in pipa and guqin but also in many other types of Chinese string and wind instruments. His style, a fine blend of strength and delicateness, exemplifies both the traditional techniques of Jiangnan music and the new pipa fingering developed after 1949. He founded the Chinese National Music Troupe in 1961, and over the past 50 years has trained many musicians and discovered new talents in Hong Kong and overseas.
