The first one is "always hope for the future". This sentence came into being because at that time, many people in the society thought that it was of little use to save China only by reform. What we need is to wait for the future and change one day. As we all know, the biggest reason why Mr. Lu Xun gave up medicine and devoted himself to literature is that he understands that only by curing China people's mental illness can we save the country correctly. Waiting for the future to solve the existing problems is undoubtedly a mental illness in his view, so he will attack directly.
The second is "refusing to change". During the nearly 300-year rule of the Qing Dynasty, the bottom people basically fell into a stage of ideological numbness. They don't know how to be flexible, how to accept new ideas, and how to accept the benefits brought by reform. And Mr. Lu Xun knows that only under the premise that most people are willing to change can advanced western ideas spread in China.
The third is that "the strong are obedient". Similarly, the long feudal thought makes it easier for the bottom people to accept it, that is, to bow to the rulers and think that those who are stronger than themselves are mainly obedient. China, which has fallen into the trap of being bullied by foreign powers, can't go on like this at all, and is willing to be a slave of others and let others extract their own efforts.
