I would like to ask calligraphers how to analyze the font and structure of each word when reading famous copybooks.

First of all, I am not a calligrapher, but an anonymous fan. Just tell me about my study experience. It is undoubtedly the main way to learn calligraphy. I think we should study hard from the aspects of brushwork, calligraphy, composition and pen and ink. Only by such careful analysis and research can we learn something.
