There are currently two theories in Red Mansions. One is that Cao Xueqin wrote the Dream of Red Mansions after the 80th chapter. Zhi Yanzhai read the complete version, but because the content after the 80th chapter did not conform to the feudal ethics, in Cao Xueqin was deliberately lost by someone (probably Gao E and others) after his death. It is also possible that his manuscript was accidentally lost during the borrowing process. Therefore, whether it was intentional or unintentional, it is impossible for his ancient manuscript to be 80 times later. content. The second theory is that Cao Xueqin died of illness after writing the eightyth chapter. The following content was not written, and the manuscript will naturally not have the following content. And I personally prefer the first statement. In other words, the content after the 80th chapter that Cao Xueqin actually wrote does exist, but the manuscript just did not dare or was unable to write the later content.
