The word "Meng" here actually refers to the Mongolian palace book, which is one of the twelve ancient stone books preserved at present. It was obtained from a declining Mongolian aristocratic family, so it was named. Your so-called "double-line criticism", "side criticism" and "eyebrow criticism" are actually plagiarism formats of comment on writing. You can look at the photocopied ancient version of A Dream of Red Mansions and have a look. For example, the double-line comment on writing is actually written in the middle of the two lines of the original text, written in double-line fine print, and all manuscripts in Menggong are Zhu's comment on writing. The side batch is written in the margin at the end of the page, and the eyebrow batch is written at the top of the page. There's no need to dig deeper. Meng Fu is the most neatly copied ancient book preserved at present. I suggest you buy it and have a look. It's available online. It is wrong to say upstairs that "Zhi Yan Zhai seems to have never reviewed this edition". These ancient books were recorded later, not to say that Zhi Yanzhai had not been examined. It's ignorant to say so. I don't know whether I am satisfied or not, but I still hope to give you some advice.
