The image is a photograph of a black plaque on a stone wall. The plaque is rectangular in shape and has Chinese characters written on it in white. The text on the plaque reads "Blocking stone" in both English and Chinese. Below the text, there is a description of the stone, which appears to be a type of stone that is used in ancient Chinese architecture. The stone is made of a light-colored stone and has a rough texture. The background of the plaque is a darker shade of brown, and the text is written in a traditional Chinese script.
