No matter what year it is published, it depends on the edition, not the earlier it is published, the more collectible it is. If that is the 120 version, it is recommended not to collect it. If it's version 80, you can collect it. Because the last forty chapters of the 120 version were written by Gao E, it can't be regarded as a true version of A Dream of Red Mansions. Even if others' subsequent works are not finished, they can only represent others' feelings, not the author's own ideas. What's more, Gao E's writing is quite different from Cao Xueqin's original intention. Last year, I saw the Story of the Stone edited by Zhou Laoye in the library, and it took 60 years to compile it. That's 80 books and a thick review. I think it's quite valuable. Of course, if you want to study a dream of red mansions more deeply, I suggest you buy an old photocopy, but it's a little expensive.
