The image is a photograph of a plaque on a stone pedestal. The plaque is rectangular in shape and has Chinese text written on it. The text is written in both English and Chinese characters. The background of the plaque is a dark grey color and appears to be made of stone.

The text on the plaque reads "Platform of Shadow Measuring by Master Zhou". Below the text, there is a description of the platform, which states that the platform was made by the master Zhou, the 4th son of Wen King of West Zhou, who was the founder of the ancient Chinese civilization. The platform was built in the early 20th century and was used to measure the depth of the earth's surface. It also mentions that the site was established in Tang Dynasty (723).

At the bottom of the image, there are two smaller text boxes, one in English and one in Chinese. The English text boxes contain information about the platform and the Chinese text boxes provide further details about its purpose.
