Who was the original author of 'Dream of the Red Chamber'?

[Cao Xueqin: After ten years of reading, I've added and deleted five times from 'Dream of the Red Chamber'!!!] He did not say that it was Cao Xueqin. Cao Xueqin was reviewing 'Dream of the Red Chamber', adding and deleting' Dream of the Red Chamber'. Who was her original author? In the earlier Jiaxu version of 'Dream of the Red Chamber', it was recorded that' Cao Xueqin reviewed it in the Red Pavilion for ten years, adding and deleting five times, compiled it into a table of contents, and divided it into chapters and chapters, titled 'Twelve Beauties of Jinling'. And the title is: 'A paper full of absurd words, a handful of bitter tears, all said that the author is crazy, who can understand the meaning.'"
