The image is a photograph of a sign on a wall that reads "Rare Treasure - Longxi" in Chinese characters. The sign is rectangular in shape and has a green background with white text. The text is written in both English and Chinese characters, with the English text on the top and the Chinese characters on the bottom. 

The text reads "Longxi was the basin used by emperor. In ancient, Xi'i, this is mirror, was usually called "Jian" and "A dragon and a phoenix were carved on the bottoms of Longxi. Full of water, when we rubbed its ears, it could give off sweet-sounding music and follow beautiful waterware. In a word, the Longxi was very interesting and valuable."

At the bottom of the sign, there is a small red button that is likely used to turn the sign on or off.
