Liang Chun-sheng (Chinese: 梁春生), known in Indonesia as Tjun Tjun, is a retired Chinese-Indonesian badminton player.

Though a world level singles player early in his career, he became one of the sport's greatest ever doubles specialists. His game was notable for its speed, power, accuracy, and aggressiveness. He is the brother of Liang Qiu-xia, also a badminton player and coach.

Tjun Tjun became world champion in men's doubles with Johan Wahjudi at the very first IBF World Championships held in 1977.^[1] They also won 6 of the 7 All England Open Badminton Championships held from 1974 through 1980.^[2] They were clearly the world's number one team during this period, often beating fellow countrymen Christian Hadinata and Ade Chandra in the finals of major events. Playing one stint at singles and regularly in doubles (first with Rudy Hartono, and later with Wahjudi) Tjun Tjun won all of his matches in three consecutive Thomas Cup campaigns (1973, 1976, 1979), all of which resulted in world team titles for Indonesia.^[3] He was elected to the World Badminton Hall of Fame in 2009.
