Which book do you think is the most profound and wise book in China?

The true wisdom embodied in the book A Dream of Red Mansions. There are both small wisdom in the world and great wisdom to get through China's philosophy, Confucianism, Buddhism and Taoism. At the end of the novel, "white is really clean" is an atmosphere from scratch. This ending alone is the pinnacle of China's novels. Most of China's novels have happy endings, because the author does not have great courage and wisdom to express great tragedies, and even some tragedies are limited to pure love. The novel A Dream of Red Mansions actually expresses the whole Chinese civilization through family and love stories. This model, in Chinese civilization, is unprecedented, perhaps unparalleled.
