Hapkido
Choi had demonstrated qualities in Daito-ryu Aiki-jutsu and often in Takeda they sent him in order to face with other persons who performed martial arts. From his return to Korea, Choi had begun to give classes of martial arts. One of his students, Ji Han Jae, had made Korean traditional techniques of kicks and punches (obtained from taekkyon and from hwarangdo) a part of the collection of techniques and in result he gave it the name of hapkido in the 1959.
