Gu Wang Yan is a newly discovered novel by Cao Qujing. Its discovery and publication attracted the attention of the world and China. Some people say that it is a greater erotic novel of China than Jin Ping Mei. Use the word "rock breaking" to describe it. The book focuses on the love between Qian Gui, a prostitute, and a poor scholar, and shows a life picture of people from all walks of life related to it. Its description is like the feeling of making the gods cry. It is pointed out that the social, intellectual, imaginative and erotic descriptions in Gu Kaizhi Yan can definitely be regarded as the epitome of traditional erotic novels, and the erotic descriptions in the book occupy a considerable space. This book is far superior to any version of erotic novels in the history of China literature, both in content and ideas. Even today, we can still call it "unprecedented", which is indeed a unique treasure of China literature.
