The image shows a display case with various artifacts on it. On the left side of the display case, there is a small plaque with Chinese text that reads "The trigger mechanism of a crossbow". On the right side, there are two small objects, one of which appears to be a trowel and the other of which is a spearhead. The spearhead is made of metal and has a pointed tip and a curved handle. The other two objects are made of wood and appear to be made of a similar material. There are also two small blue and white tags attached to the objects. The background is a plain white surface.
