Chapter 4: When Uncle draws the Korean flag for Tae-Yul and Sun-Hee. (The artifact of this chapter)

Korean flag

Uncle taught Tae Yul and Sun Hee about the Korean flag, even though they weren't allowed to. He taught them how to draw the flag and the meanings of all the different parts of the flag.
He taught them that the four symbols surrounding the flag has three parts, each representing a different cycle - the four seasons: summer, autumn, winter, spring; the directions: north, south, east, west; and the universe: sky, moon, earth, sun. And although the flag at first looked like a Japanese flag, the circle in the centre is divided into 2 parts, the top and bottom. The top being red, and the bottom being blue.
