The characters in Lu Xun's novels: Kong Yiji, Sister Xianglin and Ah Q, what caused their tragic fate? What are their shortcomings?

Their tragic fate is due to their feudal background. Mr. Lu Xun once said that feudal ethics were cannibalistic. It is against this background that Kong Yiji is a pedantic scholar who still follows the old customs. His lofty self-esteem is incompatible with the social background during the transitional period of feudal democracy, but his tragedy is more due to the ridicule and neglect of others, which makes him have no place in this society. Sister Xianglin is kind and simple, but she is still a superstitious person who abides by feudal ethics. Her tragic fate is caused by those who hurt her and those who want to help her. They confined her to the land of destruction with feudal nets. Ah Q's blind optimism and arrogance are all manifestations of China people's inferiority complex. The purpose of Lu Xun's creation is to awaken people and realize their own problems.
