This overprint is made of green-white jade, with dark brown, rust, orange-red and other mottled colors on the surface. There is a 40mm soil erosion mark on the left side. The coiled dragon is the seal base, with a slightly raised head, mushroom-shaped horns lying backwards, eyes in the shape of the Chinese character “臣”, protruding eyeballs, and an open mouth showing teeth. The fangs and huge mouth are carved with a tube drill. The dragon’s two feet are stretched forward and lie under the head, and the tail is coiled on the right side of the body. The middle is hollowed out in the shape of a seal button to support the jade seal. The dragon’s body is decorated with double-line negative hook diamond patterns to represent dragon scales. The spine is a group of twisted continuous rectangular lines extending all the way to the tail, and finally ended with a thickened spiral double negative line. There are shield-shaped patterns on the side of the face, and double negative hook cloud patterns represent joints. The bottom of the jade dragon is engraved with an eight-character inscription. A small animal crouches on the seal button, with two ruyi ears standing up, eyes protruding outward, a flat head and a wide mouth. The jade animal is symmetrically decorated with double-negative line hook cloud patterns. There is a through hole under the abdomen for tying a tassel. The seal text is a five-character bronze inscription.
