I’m not particularly knowledgeable but I’m a pretty good looker-upper and the yellow stuff is a protective membrane made of koilin that lines the inside of the gizzard to protect the muscle from acidic stomach secretions and any grit, stones or other sharp material. The muscular gizzard contracts to sort of grind up whatever’s passed through the stomach. It can pass the material back to the stomach for more enzymatic digestion or on to the intestine.
Apparently people make a tea from that gizzard lining and use it to treat digestive ailments. This Amazon listing for them (eG-friendly Amazon.com link) includes what looks like a Chinese name for them so maybe @liuzhou is familiar with that usage.
