Shanghainese say eating the head of a fly means a dish made of preserved eggs, diced meat and beans. According to the relevant public information, this dish comes from an interesting little story. The boss heard the guest say that the lobster sauce in it was particularly like flies' heads, so he was inspired to call it flies' heads. Shanghai, an international metropolis of China, is full of tall buildings and bright lights. There are not only the picturesque night view of the Bund, the magnificent Oriental Pearl, the joyful and lovely Disneyland, but also countless special foods. Braised pork, sweet and sour pork chops, eight-treasure duck and crystal shrimp are all unique Shanghai cuisines.
