Dongying calligraphy sparring
I don't know how hard you work, so choose a copybook you like and keep it in its original size, so that you can stand loneliness. First understand the brushwork, then practice the words, from simple to complex, and slowly experience. You can't write one and then do what you write, which will only repeat mistakes and not make progress. Sit straight. You are allowed to write badly, but you are not allowed to write badly. Calligraphy has a bottleneck. If there is no progress after a stage, you must come and stick to it, and it will be fine if you pass this bottleneck.
