Cai Yijiang, after textual research, thinks that this deformed man is Cao Xueqin.

Cai Yijiang believes that the abnormal old man is Cao Xueqin's biological father through textual research.

There are four main theories about the identity of Red Circle Zhiyanzhai: (1) The author says; 2 Shi Xiangyun said; 3 uncle said; 4 cousin said. These are all about the relationship between Zhi Yanzhai and Cao Xueqin.

"The author said". This statement can't stand reasoning, and it is also the most difficult to establish. There are many expressions of "Yu Er Ren", "Writer" and "Approver" in Fat Criticism. There is a clear line between the author and the approver, so there is no doubt that there are two people. And if this is the author's "cunning brushwork", those people, that is, the author, will become boastful and have low personality, which is obvious. Judging from the spirit and thoughts revealed in A Dream of Red Mansions, how can an author with an empty mind be willing to slap his mouth? And that kind of arrogant and free-spirited literati image, which is "arrogant, eloquent, eloquent" and "arrogant like a gentleman, is even more fragmented", constantly does not allow himself to do such an unbearable thing. The biggest reason for this statement is that "when the author writes a book, how can others know about it" (in Yu Pingbo), which undoubtedly takes Zhi Yanzhai as an ordinary reader and ignores his close relationship with Cao Xueqin.

"Shi Xiangyun said." Mr. Zhou picked out some comments similar to women's tone from Zhi Pi, so he decided that Zhi Yanzhai was a woman. For example, Geng wrote a line at six o'clock the second time: "If Brother Yu sees this batch, he will definitely say,' Old goods, he won't relax me everywhere, damn it!'" "Looking back, I compare Yu to a hairpin, and they are bosom friends. Why am I lucky? Smile. " Back to Baoyu, saying that "a sentimental girl accompanied her on her honeymoon" annoyed Daiyu, and he criticized Yun sideways: "I will be annoyed, too. Mr. Zhou thinks that "it's not a woman if you don't scream" and "it's a female voice again" In fact, Cao Xueqin always put himself in the position of acting for the characters in the book during his creative process. If a woman is a woman, she intends to "talk". If the villain is a villain, she imitates the villain's tone. If she was a clown, she didn't swear, and many people were arrested. In essence, approving books is equivalent to writing books. You also need to devote yourself to the environment of the book and vent your related emotional feelings one by one. When you are satisfied, you will pity others and get the most from another angle. At the same time, according to a line in the second edition of the book, Mr. Zhou criticized the saying that "drinking for people first, then drinking for people" and thought that "knowing Yan Zhai is not among people", but it must be an important role in the book. It is most appropriate to further infer Shi Xiangyun.

"Uncle said". There are two main reasons for this statement. 1. Yu Rui, a man of A Qing Dynasty, wrote in the book "Idle Pen at Jujube Window": "I have heard about the old book" A Treasure Mirror of Yue Feng "for a long time, also known as" The Story of the Stone ".I don't know why someone wrote it. Cao Xueqin got it, because the story told in the book is similar to that of his family. Because of the use of the title, he revised the book five times ... I have read the manuscript, and this book has comments on what happened in that year, which is very true. It is easy for people to call it A Dream of Red Mansions and "Baoyu" refers to his uncle, not his own portrayal. Both sentences begin with the word "smell", which should be a popular view at that time, not from his uncles Yi Ming and Lin Ming, so it can't be confirmed. This "smell" once aroused people's doubts about the copyright of Cao Xueqin's Dream of Red Mansions, and its fallacy is obvious (Fu Chayi may have made friends with Cao Xueqin, and there are 20 poems of tihongloumeng, the preface of which is: "Cao wrote Dream of Red Mansions to remember the prosperity of the romantic years. Yu Rui, ..........................................................................., said to himself:" I want to associate the word Xueqin with its name, but I don't know it. "Cao, a soldier of the Han Dynasty, didn't know his official flag. We don't know Cao Xueqin that well. How can I listen to his "smell" and believe it? Isn't it ridiculous to add the word "smell" to such a thing as "having friends with Cao Xueqin"? Secondly, Geng returned to the eighteenth session: "Before Baoyu entered the school, Jia Fei introduced him when he was three or four years old. "Fat Criticism:" The critic brought this religion, so he criticized it and burst into tears. My first sister died too early, otherwise, why should I become a basket case? "Accordingly, red inkstone called WuChun elder sister, Yuan Chun's image is based on Cao Xueqin's aunt as a princess. Therefore, according to this calculation, of course, Zhi Yanzhai should be Cao Xueqin's uncle.

"Cousin said". Zhi Yanzhai and Cao Xueqin are brothers. In chapter 22 of Jing Ben, there is a grotesque comment: "Let's talk to someone we have known before. After several years, all the scholars of the Western Qin Dynasty, Zhiyan and Xingzhai have not left one after another. Now there is only one rotten product left in Ding, and I would rather not kill it! " In the comment on writing, Cao Xueqin and Zhi Yanzhai are called "philosophers", while the self-proclaimed "rotten things" look like Cao Zhi is the same generation, and abnormal is one generation older than them. JOE's third time; "The host said,' I'm in poor health these days, and I'm sad to see the girls, so I can't bear to see them for the time being. "The pervert criticized:" I haven't made a statement for a long time, and I may wake up when I see this statement. "There is more than one grotesque self here, which can prove that he is the elder of Zhiyanzhai who is smarter than Jia Baoyu. Jia Xuben said for the second time, "In the garden in the back area. "Zhifu:" Why don't you use the word "west"? I'm afraid my husband will cry, so I dare not use the word' west'. "According to Zhi Yanzhai's respect for' Sir',' Sir' should be an elder, otherwise it will be abnormal. Cao Yin calls himself "Xitang Flower Sweeper", and his branch is extremely sensitive to the word "West". When future generations write books, they naturally avoid them. At this time, the earliest time for mass production was Xu Jianian (1754). In the above three comment on writing, no matter "Mr" or "pervert", it will not be Cao Yin himself or his brother, but only Cao Yinzi's nephew. Red inkstone is naturally the grandson of Cao Yin, so he is equal to Cao Xueqin. In addition, it seems more reasonable that Zhi Yanzhai and Cao Xueqin are brothers of the same age. For the first time, I wrote a fat criticism: "from time to time, I just hope that the Lord of nature will give me another Qin and a fat." What are the benefits of this book? "The other two are also very happy in Jiuquan." "One Qin and One Fat" also said that it is conceivable that the relationship between them should be suitable for equal brothers.

The study of A Dream of Red Mansions began in the early 1920s. 1920 When Lu Xun wrote A Brief History of Chinese Novels, all the references to A Dream of Red Mansions were in the order of the movable type versions of Biography of Qi and Biography of Gao Mu. It can be seen that Lu Xun paid more attention to paper money than to high currency. 1927, Hu Shi bought a copy of JOE, and published the article Textual Research on New Data of A Dream of Red Mansions in February of the following year. This is the first monograph in the history of a dream of red mansions, and it is also the beginning of the study of a dream of red mansions.

In addition, A Dream of Red Mansions, a Xiu Xiang block-printed movable-type edition published in191,is internationally known as Cheng Jiaben, and its original edition is also an early banknote based on fat. There are thirteen different early notes of A Dream of Red Mansions. Except that the Classic Edition has been lost, only the Fat Edition has been preserved and lost, the other twelve kinds, whether it's A Collection of Light Pieces of Jade or The Completion of Zhao Bi, are precious materials for studying the banknote edition of A Dream of Red Mansions.

There is also a new saying that the reason why Zhi Yanzhai is called Mr. may be a respectful name for women at that time, especially knowledgeable women. And according to their intimacy and Cao Xueqin's experience, most of Zhi Yanzhai is also detailed. Some people speculate that this red inkstone may be Cao Xueqin's confidante or husband and wife. But these are inferred from some modal particles on the fat batch, and the actual situation cannot be verified for the time being.
