[1] He was the first Malaysian to win a medal in the men's singles event at the BWF World Championships.

In a thrilling three-set match between the veterans (both he and his opponent were above 24 years old then), he eventually lost out to the champion from China, Xia Xuanze.

Wong played badminton at the 2004 Summer Olympics in men's singles, defeating Przemysław Wacha of Poland in the first round.

The low point of his career occurred during the 2006 Thomas Cup when he injured himself by snapping an achilles tendon while playing in a quarter final match against South Korea, and was required to rest for almost 6 months.

He has set up a company "Pioneer Sdn Bhd" with former shuttlers Lee Wan Wah, Chan Chong Ming, and Chew Choon Eng to conduct badminton programmes and hopefully produce world-class shuttlers for Malaysia.
