Regular script, the so-called whole, refers to the visual unity, and it is impossible to write in absolute size. In terms of glyphs, some words have a sense of visual expansion, so you may wish to write smaller (most of the surrounding structures), while some words have a sense of contraction, so you may wish to lengthen them when writing; In terms of strokes, some words and strokes are relatively dense, but the internal structure must be clearly explained, so the strokes may be thinner and pay attention to collection; Some words and strokes are relatively simple and need a heavy feeling, so when writing, the strokes may be full, so pay attention. The most important thing is to write the words correctly. If you write horizontally, the line spacing is the same, and the rules for vertical writing are the same. But on the whole, it should be uniform (that is, from a distance, the whole gray level should rhyme).
In running script, attention should be paid to the relationship between words (the pen breaks the meaning) and the corresponding posture of each word, but attention should also be paid to the correct writing of words, that is, the center of gravity of each word should be stable on the same axis, and it is not allowed to jump up and down or pitch left and right.
The above are some basic methods and principles, but knowing doesn't mean you can do it. It takes a long time to practice. In addition, it is also very important to "break the board", that is, to emphasize the writing changes between words, mainly in homographs and homographs, and the writing methods should be changed, especially when the space is close. Take the word "zhi" as an example. It has appeared more than 20 times in Wang Xizhi's Preface to the Lanting Pavilion, but none of them is completely consistent.
