Anyway, there is no quick way to practice calligraphy. Believe it or not, those advertisements boast that they practice a good hand in 2 1 day.
Just practice step by step. Stick to it every day, not fishing for three days and drying the net for two days.
As long as you persist, you can succeed.
As for the method, it is nothing more than imitation and improvisation. Copying refers to spreading black words on extremely thin white paper and tracing. Temporary writing is reading posts and practicing on another piece of paper.
Writing is very simple, but it is difficult to do. Talk as much as possible. It's self-esteem.
