He explained the surfing stance and how to surf safely very kindly, and he guided me to enjoy surfing more by slightly adjusting my stance throughout the two hours of surfing. I had surfed three or four times in Korea, but rather, the waves were big and I went out to the deep sea to surf, so it was much easier to stand up on the board and I was able to enjoy surfing more. I had a great time without knowing how two hours passed.
