As a historical celebrity in the capital city and its environs, Xu Dingchao has made great contributions to Wenzhou, thanks to which, the establishment of a shrine for him was approved by the Beijing government of the Republic of China. Although it is a historical monument in Wenzhou, Xu Marquise Memorial Temple (Xu Gong Ci) in Jiangxin Island is virtually rarely known by people after a century of vicissitudes. The systematic collection of first-hand information left by witnesses and those who experienced, and the restoration of the memorial tradition of Xu Marquise Memorial Temple (Xu Gong Ci) in Jiangxin Island will be an essential issue in Wenzhou’s modern history, especially in the study of Jiangxin Island culture.
