Likewise, the evaluation of research on Lu Xun is never a simple evaluation of academic history, but rather a social evaluation associated with the value orientations of those times. At present, with the return of academic logic and the growing tendency toward private research, a noteworthy divergence of standpoints and evaluations of Lu Xun research has emerged. At the same time, as a prominent discipline that has been over-interpreted, research on Lu Xun is demonstrating a tendency toward redundancy and triviality. Three fundamental paradigms are commonly employed in research on Lu Xun： historical research that attempts to explore historical materials; academic research that focuses on knowledge interpretation and aesthetic evaluation; and contemporary research that pursues the contemporary meaning and values of Lu Xun＇s ideas. Each paradigm offers an insight into and understanding of Lu Xun＇s rich and complex spiritual world; each presents a paradox of one kind or the other; and each performs different value functions.展开更多
