Chang Hon Origins Project

**updated 30 December 2017**

Originally I had linked Chon Ji with Heian Shodan, though I was unable to determine an origin for the inner forearm block in the second half of the pattern. I was previously unaware of the Taikyoku series of kihon (basics) kata, which seem to be the basis of Chon Ji and the Saju exercises (or 2 of the 3, at least). These kihon kata were developed for Shotokan, and since General Choi studied Shotokan, it makes sense that his kihon equivalent was influenced by them, albeit with a different floor pattern.

​

Chon Ji combines the Low Block -> Punch from Taikyoku Shodan with the back stance Inner Forearm Block -> Punch from Taikyoku Sandan. Saju Jirugi uses the former, while Saju Makgi uses the block from the latter.
