Born in Phatthalung, Chong Chai C.—known in the ring as Pet Ban Rai—began his Muay Thai journey at the young age of 9. Unlike most fighters who start out for sport or legacy, his path was unique: he trained to help treat a health condition. That challenge ignited a lifelong passion, transforming a necessity into a calling. Standing 170 cm, Pet Ban Rai brings a gritty, pressure-forward style to the ring, with a heavy emphasis on knee strikes, using his frame to control the clinch and wear down opponents.
