Chinese regional cooking can be said to fall into four categories that roughly correspond to the four points of the compass: north, south, east and west. However, since it is in the nature of cooks to enjoy sharing ideas and recipes, these distinctions are not clear-cut. The northern school of Chinese cuisine is often termed Mandarin cuisine or Beijing-style cooking. Each individual province has its own food history and collection of recipes, but they have influenced each other for centuries, with similar ingredients dotting the menus.
