探讨民国武侠小说尤其是“北派”的创作,徐春羽是无法绕过的存在。其作品虽然无法与还珠楼主、白羽、郑证因、王度庐、朱贞木等“五大家”比肩,然亦据有一席之地。关于徐氏的家世生平,目前学界所知甚微。通过城市田野调查,同时配合网络搜索引擎的运用,文章对徐氏的家世生平进行考索,同时以此作为学术个案,对有关研究方法予以翔实记述。 To explore the creations of martial arts novels in the Republic of China, especially the “Northern School”, Xu Chunyu can not be circumvented. Though his works can not stand shoulder to shoulder with the “Five Masters” of Huanzhu Landlord, Bai Yu, Zheng Zhengyin, Wang Dulu, Zhu Zhenmu, etc., there is a place for them. About Xu’s family life, at present little known in the academic community. Through the investigation of the urban field and the application of web search engine, the article makes a test of his family life and at the same time takes this as an academic case to give a full account of the relevant research methods.
