In fact, no matter which font you practice, it looks good, not only our common regular script, but also writing a seal script and official script with a hard pen.
If you just want to write better, then choose a post you like. If you want to practice a little deeper, you should pay attention to it. Start with regular script and see which font is most suitable for you, namely Ou, Yan, Liu and Zhao, and learn gradually and deeply.
There are similarities between regular script and running script, but there are also great differences. Regular script has the writing standard of regular script, and running script has the writing standard of running script, and the two cannot be confused. We can't think that writing regular script quickly is running script, and writing running script quickly becomes cursive script.
The focus is on practicing basic skills, one is the ability to master strokes, and the other is the ability to understand various calligraphy styles and grasp the characteristics of strokes. When the basic strokes of Chinese characters are mastered, it is possible to practice running script directly for the purpose of practical writing. Because when practicing running script, you can also train your pen control ability.
Because the standard of regular script is different from that of running script, we often see some people who write neatly, but once they write running script, they will be confused, and if they write quickly, they will become "ghost symbols". This is because they have not mastered the rules.
As a hard pen calligraphy lover, you can practice any calligraphy you are interested in, because hard pen is not as difficult to control as soft pen. But as a practical exercise, it is better to start from practicing regular script.
