1906 In March, Lu Xun applied to drop out of Sendai Medical College and was allowed to go to Tokyo to engage in literary and artistic movements. Why did Lu Xun choose to abandon medicine and leave Sendai? Lu Xun explained it more than once. For example, he said in "Scream and Introduction" that after the slide show of Japanese beheaded during the Russo-Japanese War was shown at recess, "I feel that medicine is not an urgent matter. All stupid and weak citizens, even if they are healthy, can only be meaningless propaganda materials and spectators. It is unnecessary to think that they died unlucky. Therefore, our first task is to change their spirit, and what is good at changing their spirit is that I thought it was natural to promote literature and art at that time, so I wanted to promote the literary movement. " When we analyze Lu Xun's life course and ideological track, we usually take this as the main basis.
