At the end of the book, he attached a cabinet-style calligraphy, which is still very good. This is more solid than many thoughtful works, and less vulgar than those who practice more but lack theoretical education. So this is his advantage, especially in which he said that the relationship between human talent and acquired learning is very interesting. He said that since ancient times, he has been over-educated. Every time he loses his manners, he is over-educated and still has rules, which may be a sober post for us.
He divided the people who can write books from ancient times to the present into original works, famous artists, original works and secondary works. Although it's a bit confusing, such as how to distinguish between genuine products and genuine products, in fact, on the whole, he still makes sense. We experience with vague feelings, especially under such a division, it is obvious that there are different levels among the five discourses, but there are also some biases, such as overemphasizing Wang Xizhi, overemphasizing the correct voice and abandoning Zheng Sheng (called lewdness in ancient times), and also having their own views on Fiona Fang in calligraphy, which is suitable for all ages.
Although it is a bit overkill, I can still feel its sincerity. And a lot of words can't be said without practice, so it's interesting to skim the book while taking notes, and it's worth reading again.
