Pay attention to the curve in straightness, and the cursive script should pay attention to the curve change and fluctuate at will, so that the straightness has a curve, but don't just entangle and be oily, and the strokes should be strong. Also pay attention to the changes in weight. Blindly heavy will lead to mental stagnation, blindly light will lead to vain light, but heavy must be measured, otherwise it will only increase evil.
Cursive script is a symbolic calligraphy (that is, freehand brushwork in painting). A symbol can be used instead of a word or radical (even a few words) to achieve a concise effect and receive an abstract artistic effect. Cursive scripts should be as concise as possible and can be replaced by less.
