The reason why Fat Review is valued by Redologists is that it reveals some situations in the last forty chapters of A Dream of Red Mansions.

Fat criticism, also called fat criticism, is the earliest criticism of China's traditional novel A Dream of Red Mansions. Unlike Cheng Jiaben and Cheng Yiben, which will be printed by Gao E and Cheng Weiyuan later, the fat version of A Dream of Red Mansions is mostly handwritten, and the contents of the first eighty chapters are different from those printed later. So this version is also called fat version.

There is more than one author of Fat Review. The reason why it is called Fat Review is that the representative figure is Zhi Yanzhai, one of the authors. The approvers who have signed or mentioned fat in the comments mainly include Zhi Yanzhai and deformed man, as well as Changcun (Tangcun), Meixi, Songzhai and others.

Fat critics often reveal their special relationship with novel author Cao Xueqin in their comments. Most scholars believe that the critical circle is closely related to Cao Xueqin, even relatives and elders. The author of Pangping also participated in the creation or revision of A Dream of Red Mansions to some extent. For example, Qin Keqing's death was completely deleted at the request of abnormal condition, and the deletion was recorded in the fat review.

Before the fat version of A Dream of Red Mansions appeared, Cheng Yiben, published by Gao E and Cheng Weiyuan, was the most popular version. In addition to the lack of fat evaluation, many details of Cheng Yiben are different from those of Fat Ben. Before the fat edition appeared, most critics of A Dream of Red Mansions thought that A Dream of Red Mansions 120 was written by the same person.
