Different from the legend of red inkstone, Cao Xueqin's confidante wrote comments between the lines when reading The Story of the Stone (formerly known as A Dream of Red Mansions), only for the first 80 times, which is of great help to future generations to understand the original intention of The Story of the Stone. Now there is not only a Dream of Red Mansions, but also a school of its own in the research and study of Zhi Yanzhai. The Story of the Stone is published together with the comments of Zhi Yanzhai.
