There are three main schools of "Ji cuisine", namely Zhili official cuisine represented by Baoding, Gongting cuisine represented by Chengde and Jidong cuisine represented by Tangshan. The fried shrimp section, pork tenderloin, fried crab and pot-wrapped elbow of Zhili official cuisine, the gold and silver swallowtail, roasted bear's paw and roasted whole deer of Gongting cuisine, and the hibiscus swallowtail, crystal chicken slices and sauce fish of Jidong cuisine are all very distinctive in Hebei. The "pyramid" structure formed by the mainstream faction of "Hebei cuisine" makes the mainstream faction of "Hebei cuisine" clear and covers a wider range, which is a remarkable feature that distinguishes Hebei cuisine from Sichuan cuisine, Guangdong cuisine and Shandong cuisine. On the top of the "Pyramid" are court dishes outside the Great Wall, which are different from the imperial cuisine in Beijing. Featuring delicacies and game, it has a crisp taste and unique and exquisite techniques. Down the "pyramid" is Zhili official cuisine, which is geared to the middle-end consumer groups, with rich sauce flavor and luxurious utensils. Further down are Jidong cuisine and Baoding's home cooking. There are many snacks, such as chestnut noodles, chess pieces and donkey meat, which are aimed at the widest public. It can be said that "Ji cuisine" is mainly salty and fragrant, with a wide range of materials and close to people's livelihood.
