The Code for Commercial Grading Settings starts with optimizing the commercial layout and makes detailed provisions on commercial settings at all levels in this city. According to this standard, urban commerce is currently divided into nine levels: downtown business district, regional business center, residential business, neighborhood business, professional street, new town business center, central town business and general town business. Specific indicators involve functional orientation, service target, passenger flow, service population, basic business area, etc. According to the people-oriented principle, the Code puts forward that the setting of regional commercial centers and new city commercial centers should be based on blocks, supplemented by bars, and the architectural form should adopt the mode of shopping centers. At the same time, commercial facilities in residential areas should be separated from residential buildings, while commercial facilities such as vegetable markets, bathing places and restaurants should be convenient for the people.
