Since the concept of park city was first put forward in Tianfu New District in 2018，Chengdu has started a series of exploration and practice of park city construction，involving ecology，production，life，culture，society and other aspects. In the past four years，around the goal of building a beautiful city with a high degree of harmony and unity in human，urban environment and industry，Chengdu has adhered to the development concept of changing from “producing people in cities” to “producing people in cities”，and has made many experiences in promoting sustainable urban development，especially in constructing urban ecological background，exploring creative transformation of ecological values and promoting modernization of community governance. Many innovative experiences and practices of Chengdu are worth learning from in other cities across the country.
