There are probably two reasons. First, there is little practice.
Hands are born, and hands will naturally shake; Second, there is something wrong with the method of practicing calligraphy.
Generally speaking, beginners will feel uncontrollable because they have never touched the writing brush, and the nib is soft, so their hands will shake. How to solve this problem? There is no other good way, that is, practice more, practice more, be skilled, and naturally do not shake hands.
The second reason is the problem in the method of practicing calligraphy.
First, when practicing calligraphy, you are too timid to write, and your hands will shake. At this time, we might as well be bold and write boldly. Second, if you practice small words, your hands will shake. Beginners are advised to practice enlarging the words. First, practice pen power, not wrist power. Stick to it for a while, and you will definitely overcome the problem of hand shaking. Third, the speed of practicing calligraphy. Beginners practice handwriting too slowly, and their hands will shake (but it is recommended not to do it too fast, which will lead to lack of experience in using pens, and the speed should be adjusted in time).
I have a little suggestion to overcome the problem of hand trembling. Practice more basic strokes and enlarge them, or practice long horizontal lines, long vertical lines and long arcs. These are of great benefit to the tempering of basic skills and will definitely overcome the problem of hand shaking.
