First of all, I don't think "The Story of Wu's Stone" is necessarily the real draft of "Dream of Red Mansions", because its writing is extremely poor, and there are many characters and plot bugs in the first 80 chapters. Any Internet writing master can write a much better ending of "Dream of Red Mansions" if he has the general clues about the ending of the characters in Chapter 5. However, "The Story of Wu Family's Stone" corresponds to some sketchy lines in the first 80 chapters of "A Dream of Red Mansions" and the writing of the last 108 chapters of "Love List" still makes people dare not to completely kill it. Then there is only one possibility left: the plot of "The Story of Wu's Stone" is a version of "A Dream of Red Mansions" that has not been polished and patched. Because it has not been polished, there are phenomena such as the collapse of the characters and plot bugs. However, because the character endings are fixed from the beginning, there are no bugs in the before and after comparison clues.
