Palace-style dishes in China are mainly represented by several ancient capitals, which are divided into southern flavor and northern flavor. South flavor is represented by Jinling, Yidu, Lin 'an and Yingdu, while North flavor is represented by Chang 'an, Luoyang, Kaifeng, Beijing and Shenyang. Its * * * features are luxurious and exotic, and the side dishes have certain specifications. This tradition has been preserved since the Shang and Zhou Dynasties. For example, the' Eight Treasures' mentioned in the Book of Rites (there are many different sayings, and later generations take dragon liver, phoenix marrow, leopard fetus, carp tail, roasted bird, scarlet lip, bear's paw and crispy buttermilk cicada as eight treasures), which has been in use for more than two thousand years. However, the specific content is constantly developing and changing.

In the future, eight treasures in the north and eight treasures in the kitchen will be dominated by game. By the Qing Dynasty, it was further developed, jumping out of the palace and appearing in the market, with names such as Mountain Eight Treasures, Sea Eight Treasures, Upper Eight Treasures and Lower Eight Treasures. Since the Yuan and Ming Dynasties, Palace Cuisine mainly refers to Beijing Palace Cuisine, which is characterized by strict selection of materials, fine production, beautiful shape and color, and clear, fresh, crisp and tender taste. Famous dishes include chicken breast, pork tenderloin, four kinds of gravy, four kinds of sauce, four kinds of crisp, small sugar corn-bread, pea yellow, kidney bean yellow and so on. Now Beijing's imitation food still manages this traditional palace flavor dish. Xi 'an has also successfully copied the palace dishes of the Tang Dynasty, and supplied them to the outside world. There are mainly four kinds of banquets, including Chang 'an Eight Scenes, Longfeng Banquet, Shaowei Banquet and Aquilaria Resinatum Banquet, with more than 50 varieties.
