When I was young, I wrote with a pen or ballpoint pen, and the posture of holding the pen was naturally stereotyped. So is the method of holding a pen the same as that of holding a pen? Of course not, so if you want to learn calligraphy, you must first learn how to hold a pen.
After mastering the correct method of holding a pen, find a copybook that suits you and interests you, preferably with strokes, radicals and techniques. Of course, learning calligraphy cannot be effective at once. You need to practice every day, and you can't rush for success. You must start with simplicity, practice some basic strokes first, and then practice the list.
After practicing the basic strokes, the next step is to copy the characters. Don't try to be brave and write directly according to your own preferences, which will lead to the font being shapeless and difficult to form a system. At the end of practice, you don't even know what's going on, and there is no difference between good and bad, so you can't get rid of it.
In addition, if you want to write well, you still need someone to guide you, so the effect will be faster. For example, it is often difficult for beginners to understand what kind of brushwork, right or wrong strokes, and someone needs guidance. If you have the conditions, you can also choose to enroll in calligraphy classes, which will be more conducive to learning calligraphy.
