Rudy Hartono
While still in high school, in 1974, Liem won the national championship. In the same year he participated in the All England for the first time. Later on, Liem won the All-England Men's Singles Championships in 1978, 1979 and 1981 during a six-consecutive-year run to the finals (1976–1981) of what was then perhaps the world's most prestigious badminton tournament. He was the runner-up at the then triennial World Championships in both 1980 and 1983 to, consecutively, fellow Indonesians Rudy Hartono and Icuk Sugiarto. He was a member of the Thomas Cup winning Indonesian teams of 1976, 1979, and 1984, playing both singles and doubles on the latter two occasions. He also played in the Thomas Cup in the years 1982 and 1986. He was a bronze medalist in the men's doubles together with Kartono at the 1985 IBF World Championships in Calgary.
