Coach Chang Kim Wai grew up in Sungai Siput, coming from a low income family whereby his father was a factory worker and his mother, a housewife. By the age of 12, he was selected to represent his school in badminton tournaments. During that time, he had to borrow badminton racquets from his friends because he did not have his own. Along with his persistence and commitment, this young boy was finally selected to be part of the Perak state badminton team, soon after, he joined the national team and later became a famous badminton ace in doubles. In 2003, he successfully broke into the badminton men's doubles final of the Southeast Asian Games (ASEAN), leading the race once and for all. Later in age, he built the foundation of his journey as a badminton doubles coach. The players under his wings were the pairs, Koo Kien Keat and Tan Boon Heong, Lee Wan Wah and Chong Tan Fook and many more. Currently, he is the head coach in Datuk Wira Lee Chong Wei Badminton Academy (LCWA) and still continues to instill his profession and knowledge in young shuttlers.Coach Chang Kam Wai, regarded by many "devil coach," unknown to many, is a reasonable man. Losing games to him does not matter, as long as the fire of the heart has not been dimmed. He believes that self-reflection is more meaningful to discovering our own weaknesses rather than pointless frustration when players lose in the games.He pointed out that there is also a shortage of coaches for the time being. Therefore, besides providing training to players, coaches should also focus on the coaching training regimes to always maintain the quality of badminton. Coach Chang has gained a lot of knowledge during his service in the national team and he would like to share his knowledge to those people who are interested in becoming coaches.At the age of 45, he recalled that someone had said to him before that badminton can be played for life. For Coach Chang, he has already been playing for the past 20 over years and all he had to do was hold a racquet and just do what he does best. People who were envious and skeptical of him often questioned him about his skills and Coach Chang would reply "You could have been me, but you gave up!”
