my country’s palace-style dishes are mainly represented by several major ancient capitals, and can be divided into southern and northern flavors. The southern flavor is represented by Jinling, Yidu, Lin'an, and Yingdu, and the northern flavor is represented by Chang'an, Luoyang, Kaifeng, Beijing, and Shenyang. Its unique feature is that it is luxurious and rare, 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 "Book of Rites Nei Principles" (there are many different ways to refer to them, later generations refer to them as dragon liver, phoenix marrow, leopard fetus, carp tail, bird's nest, orang's lip, bear's paw, cheese cicada) (Bazhen) has been in use for more than two thousand years. However, the specific content is constantly developing and changing. Among the Eight Treasures of Water and Land in the Tang Dynasty, there is a saying that "the peak of a purple camel comes out of a green cauldron, and the scales on a crystal plate" are not only produced on land, but also on aquatic products. In the future, game will dominate the Yinbei Bazhen and Tianchu Bazhen. In the Qing Dynasty, it was further developed. It jumped out of the palace and appeared in the market, with names such as Shan Bazhen, Hai Bazhen, Shang Bazhen, and Xia Bazhen. Since the Yuan and Ming Dynasties, palace cuisine mainly refers to Beijing palace cuisine, which is characterized by strict selection of ingredients, fine preparation, beautiful appearance, and a taste that is clear, fresh, crispy and tender. Famous dishes include chicken breast, poached tenderloin, Si Da Zhu, Si Da Sauce, Si Da Crisp, small sugar steamed buns, pea yellow, kidney bean yellow, etc. Today, Fangshan in Beijing still sells this traditional palace-flavored dish. Xi'an also successfully imitated Tang Dynasty palace dishes and supplied them to the outside world. There are mainly four kinds of banquets, including Chang'an Eight Scenic Spots, Dragon and Phoenix Banquet, Shaowei Banquet, and Agarwood Banquet, with more than 50 varieties.
