Why is there "Tale of Genji" but "Tale of Pingjia" in the famous works catalogue of Beijing Yanshan Publishing House?

My understanding is that Tale of Genji has been published by Feng Zikai 1998 People's Literature Publishing House, which is quite excellent, while Tale of Pingjia is not as well known as Tale of Genji, so it was not published in order to bring forth the new. I have seen the illustrated stories of Zhuqu Tale, Pingjia Tale and Genji Tale published by Yunnan People's Publishing House before, which are very good.
