How to write like a calligrapher (not a brush)

I've been practicing calligraphy for a long time, and I'm beginning to be similar to you. I used to write badly, and I often suffered in exams. Later, I made up my mind to practice calligraphy. When I was in high school, I had a teacher who wrote very well with pen and ink and won an award in the province. I just learned it from him. Now I want to talk about my caution, hoping to help you: writing is a hard process, and there is no shortcut, just to master certain rules and practice more. You'd better practice the basic strokes first, that is, fold them horizontally and vertically, and then paste them to a certain extent, so that you can not only improve yourself over time. In addition, my pen calligraphy is ok, and I can communicate with you if I have any questions.
