The important thing in learning calligraphy is not imitation, but comprehension. Calligraphy pays attention to artistic conception and uses a pen to break the meaning. I study calligraphy. I put my own personality, copying experience, knowledge, understanding of nature, understanding of others and understanding of people's hearts into my words. There is progress. Another reason is the learning style. I think he has something to do with your personality. People with strong personality should learn from Ou Yangxun's writing style, be gentle, and learn from Zhao Mengfu's writing style. The learning style is consistent with your personality, and the progress is obvious, but the progress is slow.
First of all, if you are interested in calligraphy, you won't write badly. Perseverance is also an essential factor. For beginners, first of all, learn to copy the calligrapher's copybook (whose calligraphy is the best, don't change it, imitate it for a long time, don't change it every three days, change it every two days). After copying, when writing, you should observe the structure of a word, radicals, as small as each stroke, and how to arrange it to make the word look better.
