Ji Nei Jin is sometimes mixed with duck gizzard lining. The main differences are: Ji Nei Jin skin is soft and thin, easy to tear off, so it is mostly complete with two halves connected, yellow or yellow-green, with ring-like protrusions. Duck gizzard lining skin is hard and not easy to tear into a complete oval shape, mostly disc-shaped, dark green, with fewer and less obvious wrinkles, the fracture surface is thicker and dull, mostly in broken pieces, the color is dark black-green, and there are no ring-like protrusions. Goose gizzard lining is mostly round or broken pieces, yellowish-white, smooth and dull.
