The stuffing of crab shell yellow is salty and sweet. The cake is made of the oily noodles and the yeast noodles are made into a flat round cake, and the cake surface is adhered with a layer of sesame, which is baked on the wall of the furnace and baked. The fillings are salty and sweet, salty with onion oil, fresh meat, crab powder, shrimp, etc., sweet white sugar, rose, bean paste, jujube and so on.
