Have you practiced 7000 words of Jing's running script?
Yes, when I first started writing, I started with the simplest strokes, which proved that the fewer strokes, the harder it is to write. Because of personal habits, I am not sure about the angle of the pen tip, and it is easy to write too hard, which leads to unsmooth writing and some fonts are uncomfortable. Observe first, then write, observe the trajectory of the pen and the angle of the nib when writing the model characters, and read it clearly before writing.
