The image is a photograph of a sign in a park or garden. The sign is rectangular in shape and is made of a dark grey material. It has Chinese characters written on it in white and green. The characters are written in both English and Japanese.

The text on the sign reads "Yang Yi, an astronomical instrument invented by Guo Shoung, was a kind of sphere surface sundial made up of an upward kettle, a cross, and a set of plates for shadow measuring. The exhibition here is a quarter size of displacement. By observing, people can view the sphere surface position of the sun and its movement during the whole process of solar eclipses and its division changes can be observed at the same time."

At the bottom of the sign, there is a small illustration of a sun. The background of the image is blurred, but it appears to be a grassy area.
