The image is a text-based information about the first capital of Baekjeong, which is located in the Hangang River. The text is written in Korean and is in black font on a green background. 

The text explains that the capital was changed to Hanseong in the wake of continued expansion. Hanseongsong is a name referring to both the north fortress where the royal palace was located, and the south fortress where an annex palace was situated. North fortress is present-day. Pungnaptoseong Fortress, and South fortress is the town outside the two fortresses and the royal tomb area (Tombs of Seokchon-dong) all belonged to Hansseong.

At the bottom of the image, there is a subtitle in Korean that translates to "The first capital" in English.
