He was one of the world's leading players in his era, known for his cool and steady play.

In China he is nicknamed "sticky candy" (牛皮糖), owing to his much-used tactic of using long rallies to pressurize an opponent into making mistakes.

Han won the 1985 IBF World Championships beating Morten Frost in the final.

He also won a bronze medal at the 1983 IBF World Championships and played singles for China's world champion Thomas Cup (men's international) teams of 1982 and 1986.
