Although the author, Mr. Lu Xun, explained hope in the preface to the English version of "Wild Grass"-"I am amazed at the depression of young people; As "hope", people still often regard "hope" as a work expressing Lu Xun's pessimism and disappointment. It reveals the author's inner shadow, dissects his inner contradictions, or denies the "helpless hope of self-deception", which shows Lu Xun's desperate spirit of anti-Japanese war. However, even through simple logical reasoning, we can think that these understandings are inconsistent with the author's original intention: why do things that "marvel at the depression of young people" express their pessimism, disappointment, inner shadow and despair? Is it to show understanding to young people and to be in the same boat? If so, isn't it more depressing for depressed young people? Yes, Hope makes people feel the author's inner contradictions, depression and heavy emotions, but at the same time it is exciting and exciting. Therefore, the contradiction, depression and heaviness revealed in the article show Lu Xun's deep concern for young people and his boxing intention.
