Ul Ji
Ul Ji is one of the very first Chang Hon patterns ever created, and like its brothers Hwa Rang and Choong Moo, it displays a large Karate influence. However, as Ul Ji is one that I have not yet been properly taught, my analysis will not be up to the standard of the previous patterns.
Ul Ji contains some jumping kicks and kicking combinations not seen in Karate kata. I've written about kicking here.
The following videos were used as reference:
ITF Legacy performance of Ul Ji.
Hirokazu Kanazawa performing Jion, Gankaku, Heian Sandan, Bassai-Dai, Heian Godan, Tekki Nidan (Shotokan).
Ul Ji's opening move is similar to this backward step in Jion.
It follows with the low X block, high X block combination found in Heian Godan, later reused in Toi Gye and Yoo Sin.
Ul Ji does a 180 degree turn into a backhand, kicks the hand, then lands with an elbow strike. This sequence is also found in Heian Godan. Ul Ji is the only Chang Hon pattern to follow the hand kick with the elbow as is common in Karate kata.
Ul Ji's hands on hips position comes from Heian Sandan, later resued in Toi Gye. Ul Ji keeps the hands on the hips while adding a kick, whereas Heian Sandan keeps them there while stomping into a sitting stance.
Ul Ji continues with a minor piece that resembles Naihanchi/Tekki Nidan, though with a horizontal punch found in Tekki Shodan.
Like many other patterns, Ul Ji also uses the opening backfist of Bassai-Dai. But, unlike later patterns, Ul Ji also uses the preceeding position used in Bassai.
After a high block, kick, and punch, Ul Ji performs this piece of Heian Sandan, later reused in Do San. However, the final stance more closely resembles the original here than it does in Do San.
After a turn into a position resembling the opening movement, Ul Ji performs a jumping font kick and some X blocks. This is reminiscent of a sequence found in Chinto/Gankaku, though a similar one exists in Kushanku/Kanku-Dai; that is, a jumping front kick found next to X blocks.
Soon after, Ul Ji performs a backward jump. This is interesting because the spinning jumps in Choong Moo and Sam Il are clearly based on the jump in Enpi, which is a 360 degree spin that also moves backward. Choong Moo and Sam Il's jumps spin while remaining in place, whereas Ul Ji's moves backward without spinning.
Seeing as Choong Moo and Ul Ji were among the first 3 patterns, it's possible that Choi wanted the jumps to be distinct. That being said, Sam Il is one of the original 5, and its jump is identical to Choong Moo's, so who is to say.
Ul Ji follows with a kicking combination, then eventually performs the blocking sequence from Bassai-Dai reused at the end of Toi Gye, though Ul Ji performs just two blocks as in Bassai.
