Abstract: At present, most qualitative research on sport is lack of imagination due to the shortage of openness. It is mainly manifested in using presupposition instead of experience, mechanically using literature, inflexible data collection methods, repeatedly "frying leftovers" in research conclusions, etc. This study, by the reference to the grounded theory's emphasis on experience-common sense-literature which places sports events in a dynamic and structural situation and by means of the strategies of close-in comparison, far-out comparison and flip-flop techniques, opens up the controlled, pays enough attention to unexpected empirical materials, flexibly deals with the substance theory, formal theory and interdisciplinary theory, and compares the obtained empirical materials with all kinds of literature at any time. Besides, the possible innovation points are located through the continuous abductive reasoning of "data-induction-deduction", and in the meanwhile the dialogue distance between experience and theory is enlarged thus to form imaginative research conclusions.
