Po-Eun is learned at 1st dan black belt for the ITF and has thirty-six (36) movements and the right foot returns to parallel ready stance.

Po Eun is the pseudonym of a fifteenth century Korean poet and scientist called Chong Mong Chu. Chong is also revered as a great patriot, having penned the lines "I would not serve a second master though I might be crucified a hundred times." The pattern movement plan denotes his unerring loyalty to the king and country towards the end of the Koryo Dynasty.

In depth knowledge:

Named after the scholar, poet and faithful servant Chong Mong Chu. He lived during the Koryo Dynasty and became a trusted servant to the king, who had much confidence in his wide knowledge and good judgement. He also visited Japan & China as a diplomat on behalf of his king. He participated in many national projects and also founded an institute devoted to the theories of Confucianism. He was also a pioneer in the field of physics.

Yi Sung Gae (the first king of the Yi Dynasty) tried many times to persuade Chong to join him, but he refused by penning a poem:

"Even if, I may die, die a hundred times,

Even if my skeleton may become dust and dirt,

And whether my spirit may be there or not,

My single-hearted loyalty to the lord will not change."

This convinced Yi Sung Gae that Chong Mong Chu could not be swayed and on 4th April 1392, he sent an assassin to Sonjuk Bridge to kill Chong with an iron hammer. The death of Chong Mong Chu was seen as the catalyst to the eventual overthrowing of the Koryo Dynasty in July 1392.

Sonjuk Bridge is now seen a symbol of loyalty by the Korean people. There are several memorials dedicated to Chong Mong Chu, including the Hama monument, which demands that all passers-by should dismount from their horse.
