The image is a black and white illustration of a part of an axle-gang, Jian, Guan, Wei. The illustration is on a white paper with Chinese characters written on it. The main focus of the image is the axle, which is a cylindrical shape with a pointed end and a flat base. The axle is connected to a series of pipes and tubes, which are also connected to the axle. The pipes are arranged in a way that they form a cross-section, with the tubes on the left side and the tubes in the middle. The tubes are connected by a series on the right side, and the pipes are attached to the ends of the axle with screws. The image appears to be a technical drawing or diagram of the parts.
