Master Choi enjoys seeing his students try Korean wrestling, SSireum at the beach. He taught it to his students.

[Counselor of main Kyokusin Kai Kan] (He is talking about Grand Master Choi(Oyama).)

When people holds some events like welcome party or farewell party, he ordered only Korean dishes unconditionally. At first, we had never seen such Korean dishes as Kimchi, we complained much saying "what's this, on earth?" but Master told us to eat them as they are not for just looking, so we had to eat Korean dishes. And now everyone likes Korean dishes. I feel Korean dishes builds power inside when we have them. Japanese dishes are not... I believe.

Last scene is he demonstrates basic punching at the beach training.
