Background: The development of health theory has deepened the function of city parks. It is urgent to explore the action mechanism and practical experience of city parks from a health promotion perspective. Methods: This paper adopts the dynamic tracking method, which has been widely used in the study of city park health problems. Between 2009 and 2010, the author participated in the redesigning project of WLCP. From 2014 to 2018, the author participated in the health management project of WLCP. Additionally, in order to complete the study more accurately, the author conducted three interviews between April and May 2020. After transcribing, condensing, and categorizing talking content, we summarized the theme structure and results.Results: First, the transformation of the health benefits of city parks depends on the use of residents, and the supportive design is the intermediary mechanism for stimulating park use. Second, residents' demand for health is no longer limited to physical and psychological, but includes a higher level of spiritual satisfaction and a comfortable environment. Third, the supporting design of city parks should include a health management system, and a standardized and normalized management system can alleviate health damage. Conclusions: The theoretical framework, action mechanism and practical experience of city parks from the perspective of health promotion proposed may be applicable to other cities at home and abroad.
