The image is a text-based slide from a presentation on written characters. The slide is titled "Written Characters" and is written in black text on a white background. The text is divided into two columns. 

The first column explains that at Tomb 1 of the Daho-ri site in Changwon, archaeologists uncovered brushes and a small knife from a bamboo basket that was buried beneath the coffin. The brush and knife seem to have been used to write and erase characters on strips of wood or bamboo. The discovered artifacts also included four copper rings that likely served as weights, indicating that, in addition to written symbols, the ruling class of the Samhan society also used weights and measures.

At the bottom of the slide, there is a paragraph that explains the purpose of the text.
