Born as a son of gangster members in 1968, PARK Hyun-sung is a natural-born fighter. Since his childhood, he was committed to be an Olympic champion, and he actually received a trophy at the National Sports Festival in 1982. Three years later, he became a bronze medalist at the King's Cup International Amateur Boxing Tournament. Yet he eventually became a gang member like his father, after failing to be selected to the national team in Seoul Olympic, 1988. Out of the boxing ring, he was still an excellent fighter which led him to jail several times. While expanding his territories, he found a way to become rich. And he has set up a boxing gym for all.
