The image is a photograph of a piece of paper with Chinese text written on it. The text reads "Cities and Trade" and is written in both English and Chinese characters. Below the text, there is a subtitle that reads "During the Spring and Autumn and the Warring States Periods, cities increased in size and number. With growth in trade, metal currencies were circulated and each state set its own standards for weights and measures." The paper appears to be old and worn, with some creases and wrinkles on the edges.
