taekwondo1-3, Exercise 1: The kwans

Model answer:

A kwan (관, 館) literally means "building" or "hall"; in martial arts it can also mean a school or clan of martial artists who follow the same style or leader.

Any three of the five (per the Kwan article):
- Song Moo Kwan: Ro Byung-jik; had studied karate under Gichin Funakoshi in Japan (founded 20 March 1944, Kaesong).
- Chung Do Kwan: Lee Won-kuk; taekkyeon in Seoul, Shotokan karate in Japan, kung fu in China (September 1944).
- Moo Duk Kwan: Hwang Kee; taekkyeon and Chinese arts; taught Hwa Soo Do, then added Tang Soo Do after 1946 (1945).
- Ji Do Kwan: Chun Sang-sup; Shotokan karate with Funakoshi; called his art Kong Soo Do (3 March 1946).
- Chang Moo Kwan: Yoon Byung-in; Chinese kung fu, and Shudokan karate at Nihon University (1946, as the YMCA Kwon Bop Club).
