Wai-luen Lo (1939-) is a path-breaker in Hong Kong Literature research. She takes the collecting of Hong Kong literature and cultural publications, historical materials as her lifelong duty, and is considered to be one of the most capable scholar to write Hong Kong Literature history. However, Lo has strictly refused to undertake such writing by claiming a lack of history consciousness. Her great attachments to historical materials with determined refusal on history writing, is quite an uncommon academic attitude among Hong Kong or even contemporary literary scholars. Every scholarship has its own origin just like every tree has root. This paper unfolds the establishment of Lo's literature research method by tracing her overseas study experience in the early-1970s. It proposes that the card research method applied by the Institute for Human Sciences of Kyoto University, hit it off with the modern literature research that Lo occasionally started there. Lo's unique academic research principle is deeply influenced by the Kyoto School's multi-textual historical criticism which integrated with anthropological methodology, as well as the Japanese joint-research academic culture. This paper also illustrates the inheritance and inspiration of Lo's research method, through examining her works and design of literary curriculum.
