Lu Xun is very particular about reading methods. He advocated learning from others, saying, "No matter what the book is, you should always turn it over, or read the preface, or read a few pages." It has the advantages of broadening ideas and increasing knowledge. For the more difficult required books, his view is to bite the bullet and read on until you understand them thoroughly. He also advocated choosing his favorite books for in-depth study on the basis of "extensive reading". In his research, he advocated independent thinking, paying attention to the combination of observation and practice, and "reading this living book in the world with his own eyes" and "making the books he read come alive." For the place that he can't understand, he thinks that "if you only see that place when you are in doubt, you won't understand it no matter how long you see it." So jump over and move on, so even the previous place is understood. " Lu Xun attached great importance to using newspaper clippings to accumulate materials. He once said: "No matter what, if you collect information one after another for ten years, you can always become a scholar."
