Kang Ik-joong paid attention to the theme of the most Korean subject, moon jar, and 'connection' in Hangul. Because moon jars are large in size, it is difficult to make them into a spinning wheel at once, so most of the time, the upper and lower bodies are made separately. Therefore, there are some that are evenly proportional, but the round shape varies depending on the taste of the person who made it. Kang Ik-joong's work contains the artist's wish to connect up and down, you and me, the South and the North, and the whole world. Furthermore, the flow of time, past, present, and future, continues smoothly in a mysterious moon jar.
