Abstract: HU Shi had devoted himself to the publication and distribution of A Dream of Red Mansions of CHENG Wei-yuan’s version B and made it the most popular version with the largest amount of readers. He thought this version and the Zhiyanzhai edition were the different forms of the same novel A Dream of Red Mansions. And he compared different versions of Genshen, Qixu and CHENG’s in his late years and found that the CHENG’s version was the most popular one. He had considered the last forty chapters of the novel had been written by GAO E but had never depreciated and excluded them. Instead, he took ZHOU Ru-chang’s complete negation of them as nonsense.
