Chuang began to play table tennis very early because his parents and his older brother played, too. At the age of eight he had his first appearances, for example the Mini-championships in Taiwan. As the parents saw the talent of their son, Chuang got a coach and his parents tranied him, too. 1993 Chuang traveled (to the table tennis capital) China. This moving was no easy decision for his mother Li Gumei, but it doesn't get back at home. And to that time the family Chuang wasn't very rich. Chuang had to train in very hot gyms and sportclubs. The working had success: In 1998 he got to the Taiwanese National team.
