What do the evaluation system of red inkstone and the elevation engraving system in A Dream of Red Mansions mean respectively? It is better to have a detailed explanation. Thank you.

Cheng Ben, or Cheng Gaoben, is a book with special value in various versions of A Dream of Red Mansions. The so-called Cheng Ben mainly refers to Cheng Jia and Cheng Yi. In the winter of the fifty-sixth year of Qianlong (A.D. 179 1), under the auspices of Cheng Weiyuan, Gao E participated in the revision and arrangement and published 120 volumes. Printed in wooden movable type by Suzhou Cui Wen Bookstore, the full name is "Ganlong Xinhai Cui Wenmu Movable Type Bookstore". The following year, in the spring of the fifty-seventh year of Qianlong (A.D. 1792), Gan Long Renzi Cui Wen Bookstore was published. Just over two months apart. In the 1920s, Hu Shi named these two books Cheng Jiaben and Cheng Yiben respectively. Later, the versions of A Dream of Red Mansions were mostly studied under the names of "Cheng Jia" and "Cheng Yi". The reason why Cheng Ben is a book of A Dream of Red Mansions with special significance is as follows: First, from these two books, A Dream of Red Mansions spread, from manuscripts to engravings. Although this book has appeared in temple fairs before and its readers have expanded, it is only circulated in the form of words. Of course, it takes a long time to complete a book, and the number is limited after all. Moreover, a book is worth "tens of gold", which is equivalent to dozens of stones of rice, and it is expensive. This will inevitably affect the widespread circulation of this book. One reason is that there are few written books that can be seen today. After the print edition came out, the circulation was greatly expanded. Printed versions can be printed in large quantities. Relatively speaking, the material cost of a book is much lower. The range of readers who can afford this book has expanded. Later, this book was engraved for a while and widely circulated. The main reason, of course, is the artistic charm of the book itself, but the publication of the sub-class is also a factor to promote the spread of this book. Therefore, the significance of the first printed version of elevation should not be underestimated. Second, the two books on elevation are 120 volumes, and the capital is Xiu Xiang. At that time, it was called "A Dream of Red Mansions in Xiu Xiang". At that time, although people were also talking about the differences between versions of A Dream of Red Mansions, the attraction of the "full version" was undoubtedly much greater than that of the eightieth version. Cheng Ben has the last forty chapters, which means that the book has an ending, which has also played a beneficial role in promoting the spread of this book. Since then, most of all kinds of block prints have been based on Cheng Ben (especially Cheng Jiaben), such as Fu Jia Jieben, Benya Cangben, Dongguan Pavilion Ben, Shuangqing Xianguan Ben, Miaofu Selected Ben, Woyun Mountain Guanben, Yujin Benyuan, etc., forming the so-called "Cheng Ben system". From this point of view, Cheng Ben's position in various versions of A Dream of Red Mansions can not be ignored. Third, there are several different versions of Cheng Ben's The Last Forty Chapters, such as Cao Xueqin himself (or basically Cao Zuo), Gao E's sequel, and other authors. Each family has some reasons to support its own statement, and it is still difficult to judge who did it. However, judging from various indications, it seems more likely that it was accepted by Cheng Weiyuan a few years later and revised by Gao E (Gao E also made many revisions to the first eighty chapters). But in any case, the problem of the last forty chapters of Cheng Ben, especially the question of who is the author, is still worthy of in-depth study. In addition, the original version of Cheng Ben is an evaluation version of Zhi Yanzhai, but there are still some different opinions on which of the various fat versions is closer to the original version of Cheng Ben. Judging from the convergence of versions, Cheng Ben is closer to Dream Ben. I have seen this problem in the dream book, so I will repeat it here. From the above aspects, among the various versions of A Dream of Red Mansions, Cheng Ben is indeed a book with special value. Although its text has changed a lot compared with the fat version, it is far from the original, but its version value can not be ignored. Zhi Yanzhai, the author of A Dream of Red Mansions is Cao Xueqin, which is less controversial. However, as a critic, Zhi Yanzhai revealed something hidden in the book, showing readers and researchers a maze of more than 200 years. There are different opinions about who he is and what is his relationship with Cao Xueqin. The existing version system of A Dream of Red Mansions can be divided into two systems. One is the fat evaluation system that only circulated the first 80 times and kept the comments of Zhi Yanzhai. The other is the Cheng Gaoben system pieced together by Cheng Weiyuan and Gao E, which deleted all the comments of Zhi Yanzhai and continued to write 120 times. The so-called fat review is the sum of all the copied copies of "The Story of the Stone" plus fat reviews. These manuscripts retain a large number of red notes, and some important manuscripts are engraved with the words "Red inkstone re-evaluates the Story of the Stone", so people generally refer to these early manuscripts of the Story of the Stone as fat reviews or fat reviews. Someone once wrote an article criticizing Zhi Yanzhai. He thinks that Zhi Yanzhai is a later scholar than Cao Xueqin. He won the trust of Cao, got some manuscripts, and became famous in the name of the author. If we look at it from this angle, Zhiben is simply a poisonous weed full of cancer, leaving behind all harm and no benefit. Most people who hold this view refute Zhi Yanzhai's comments from the contents of Cheng Ben 120 novels, and think that the comments are absurd, self-contradictory, full of self-promotion and serious exaggeration. However, from the textual research of the fat book system, it is undeniable that the fat book comes first and the craft book comes last, and only the revised version of the first eighty copies can be compared with the fat book. If the reader has two versions at hand, compare the first part of the novel. In addition, in the heyday of novels in Ming and Qing Dynasties, book reviews have not only been regarded as the storyteller's understanding of the novel's content and appreciation of the text, but have gradually evolved into a supplement and re-creation of the overall structure of the novel. This started with a generation of legendary man Jin Shengtan commenting on Water Margin and The West Chamber and incorporating them into his own creation, and Mao Zonggang and his son revised the Romance of the Three Kingdoms and Zhang Zhupo's penmanship under the guise of books. As a novel, especially in the Ming and Qing Dynasties, many novels have the characteristics of unofficial history's hearsay, and it is indispensable to discuss the ruling and opposition parties and attack the current politics. In order to avoid the persecution of the literary inquisition and achieve the purpose of the novel being handed down from generation to generation, the phenomenon of deliberately using metaphors in novels is extremely common. For example, Jin Ping Mei obviously satirizes the family affairs of Yan Song in the Ming Dynasty, but sometimes because the historical facts are buried too deeply, readers only pay attention to the superficial plot content and cannot pay attention to it.
