It was Byon Oh Park, who introduced the regulated form of taekwondo and started to teach to some new taekwondo instructors. Of those, Percy Vergara and Juan Infantas were the YUHmain instructors and the ones who started the dissemination of taekwondo to bigger audiences. Both Percy Vergara and Juan Infantas started to run a Taekwondo Club in the San Marcos University. They also opened up a new club, Black Belt Taekwondo Club where most of their best students from San Marcos continued training.
