How to evaluate Gao's Miscellaneous Book Preface?

I'm not a professional, so I'd like to make some suggestions. Single literary level, average. Friends who don't usually read classical Chinese see that ordinary people really use words to arrange sentences, surpassing ordinary people, but only surpassing ordinary people and not studying classical Chinese too deeply. Of course, there are not many people in Rainbow Bo throughout history. Gao himself also said that he can't be as good as his predecessors, which is a humble truth. The preface does have its poet's feelings, which are ingenious and flawed. Experience, thoughts, achievements, etc. Not as tall as myself, so I won't talk about others. When some friends talk about music, I think they can only say that they are popular or not. Their professional requirements are only to entertain the public, so there is no need to compare them. Singers or artists who are not very popular with young people still have some capable people.
