The SCD advocates research of the city's growth and development from different angles, especially those from the surrounding and everyday life. The Xiangmihu food street located on the south of the Planning Building has been evolving from a famous resort and theme park in the 1980s into today's most popular dining place in Shenzhen. While enjoying the gourmet, urban planners and designers should not take this spontaneous change as a blind spot in their profession and ignore it. Rather, the flexibly transformed and appended diners and grill shops have demonstrated the non-professional wisdom, principle of economy and sustainable strategies of temporary structures. In addition to exploring the memories of the city and documenting the historical changes of Xiangmihu, a main part of the research is to initiate the survey and mapping of the existing Xiangmihu temporary structures, which serves as the basis of informal space research to investigate the inspiration of spontaneous city on city planning. The research will take an open and expansive attitude to broadly combine academic groups/ individuals to participate in. while researching the Xiangmihu food street, the SCD could also try to build an open academic platform for cooperation.
