This chapter begins by defining Areas, introducing the cognitive frameworks and key issues related to Areas, as well as the theoretical foundation for the integration and reinvention of multiple Areas. Subsequently, Areas in existing multi-plans are discovered, compiled and classified into dominant spatial intervention sectors such as Urban-rural Development & Control, Land administration and regulation. For those above, a detailed analysis is provided on their contents, functions, spatial characters, and intervention attributes. Finally, the chapter explores the Area reinvention approaches for One Blueprint, reorganizing the multi-Areas to unified Area zoning framework, and offers programs for reinvention strategies.
