The image shows a round manhole cover on the side of a road. The cover is made of metal and has a unique design on it. The design is in the shape of a square with a grid-like pattern in the center. The grid is made up of small holes and lines, and there is a small hole in the middle. On the top of the cover, there are two yellow signs with Chinese characters written on them. The signs appear to be warning people not to enter the manhole. The background of the image is a red pavement with white lines marking the boundaries of the road.
