The authors don't make clear whether this later reference to "Yun Moo Kwan" alludes to a revival of the older kwan by individuals affiliated with the original group, who were reluctant to give up the connection with the original style (like Kyo Yoon Lee), or if this represented different individuals using the old name to establish something new. However, the idea of a second or "annex" "kwan" called "Yun Mu Kwan" could help explain the persistence of "Yun Moo Kwan" as a karate style outside Korea long after the old Chosun "Yun Mu Kwan" had closed its doors and its karate practitioners had re-established themselves under different names. Some practitioners of the original kwans, including some using the "tang soo do" name (another Korean version of the original meaning of the Japanese term "karate-do"), remained outside the new system of "taekwondo". Both Jidokwan and Han Mu Kwan exist today largely "within" the taekwondo family rather than as active, stand-alone styles, while the Yun Mu Kwan name lingers in different places. There are still practitioners, for instance, using "Yun Moo Kwan" or "Yun Mu Kwan," particularly in parts of Latin America. For the most part, these practitioners have continued to emphasize the Korean reliance on high kicking, large movements and flashy leaps and acrobatics. One variant evolved, however, in New York City where a Korean practitioner named Min Pai began teaching the style after emigrating to the United States in the 1950s. His early efforts led to the introduction of the style to parts of Central America through one of his early students, Francisco Miranda, who helped popularize karate in his native country of El Salvador. Pai had come to the United States at the age of twenty and, according to his successor, James Stewart, worked as a hospital orderly for a time to earn enough to survive while attending a local college. He taught himself English as he went along, largely, as he confided to Stewart, by going to English language movies. But he found his true vocation when he began teaching the Korean fighting art he had become accomplished in back home. In the early days of his involvement in the martial arts scene he would seek new skills by apprenticing himself to more senior karate masters, Stewart has stated, like Jhoon Rhee, one of the early pioneers of taekwondo in the United States.
