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. He was elected to the World Badminton Hall of Fame in 2009.
