At the end of the novel Du Shiniang's Furious Treasure Chest, Li Jia's serious illness and Sun Fu's sudden death showed the author's pessimistic attitude towards human nature. The author believes that human nature is selfish and dark. People's life and death and happiness do not depend on their own efforts, but on the decisions and fates of others. This kind of thinking still has some enlightenment today because many problems in society are related to human nature.
