The name of a tasty dish, the head of a fly, is actually a stir-fried dish composed of beans, preserved eggs and diced meat. It is said that there is an interesting story about the origin of this "fly head". Stir-fried preserved eggs with beans is a very common snack in Taipei restaurants, but one day the boss was inspired to call the dish "fly head" after listening to a guest telling him why there seemed to be many fly heads in the dish. A small misunderstanding made a strange dish, and the "culprit" who confused the guests with flies at that time was the lobster sauce in this dish.
