Abstract: The comment of Chin Ping-Mei from four aspects made by ZHENG Zhen-duo is highly summarized, profound and unique. And it stands for the top level of researches of Chin Ping-mei in modern China. He has contributed a lot to the sexual description in the novel, but he lacks fundamental understanding of such description in a large scale. He has taken such description as the trash, and hence negated the novel wholly and overlooked its value, which is, of course, a great pity. He attempted to prove that the novel had been written in the middle period of Emperor Wanli with Xin Xin-zi’ Preface to Chin Ping-mei of which origin was unknown. This is unconvincing. Further, from the signature Shandong Tubai, he took the author of the novel as one who was from Shandong and vetoed the possibility that the author was from South China. This, obviously, is wrong.
