The whole device is made of jade, with dark brown and dark green, and the local dark green changes to light yellow. The utensils are shaped like a side-looking bird, with raised round eyes and a pointed beak extending forward. The body is carved with gouyun geometric patterns, and the tail of the wing is carved with straight lines to express the outline of the feather. A round hole is drilled at the lower end of the tail for threading, and the edge lines are neat and the outline is stretched.
