Calligraphy learning is very simple: first, choose posts (this is very important, you need to cater to your own aesthetic and writing habits, and only those who suit you can get twice the result with half the effort), second, practice plans (break down posts into strokes and learn gradually), and third, learning methods (you need to practice regularly and quantitatively every day). If you follow this method, you can improve your writing level by studying hard for two months.
If conditions permit, it is recommended to learn China's calligraphy from the first grade.
