How to explain calligraphy with Chinese studies?

First of all, calligraphy lines are of high quality. The tempering of lines requires a lot of training and solid basic skills. Which lines are of higher quality, you can refer to Huai Su's Autobiographical Post or the works of modern famous calligrapher Xian. Secondly, the spelling is correct. Today's calligraphers, because of their uneven cultural literacy, often make spelling mistakes and become a laughing stock. For example, the title of a CCTV TV series recently misspelled the word "red" as the word "anus", and the leader of a book association often misspelled it, which was really insulting. And skillful brushwork, harmonious composition. Brush strokes are the basis of a book. To write a good work, a calligrapher must first be familiar with the brushwork, and then he can write with confidence. Just like Sun's so-called "walking is mountain safety, leading the way is spring full". The composition should deal with harmony and the spacing between rows should be reasonable. "Thin as the first month, falling among the stars." There can be no conflict.
