The image is a photograph of a sign on a glass door. The sign is white with black text written in Chinese characters. The text reads "The Front Line of the Communication" and is written in both English and Chinese. Below the text, there is a subtitle that reads "Gansu served as one of the regions in China where earliest bronzes have been found. The advanced bronze culture and domestication of the horse promoted the economic development and the enlargement of the front lines of adopting and spreading the western and eastern culture in China." The sign appears to be located in a museum or exhibition space.
