First, skills: what method to write, writing skills. For example, reverse stroke, reverse stroke, side stroke, partial stroke, imaginary stroke, reverse stroke and other techniques. Many people write well in life, but it is not skill. Therefore, even if you write well, you can't be a calligrapher.
Second, composition: that is, the method of planning the layout of the article. The same text, different layouts will have different effects. For example, the writing of horizontal couplets requires neatness, but it is not necessary to emphasize these when writing a word. In addition to the overall layout, a calligraphy work should also emphasize the methods of reality, size and relaxation. Generally speaking, when writing running script and cursive script, it will be used more, while writing regular script, seal script and official script is more neat.
Third, in addition to the above, the writer's experience is also very important. The artistic conception of the words written by an educated and open-minded person will be very different from that written by a craftsman.
