The formulation of hard pen calligraphy is open to question. After practicing the brush, the hard pen will naturally come, and it is not difficult, otherwise it will not be like this! From hard pen to writing brush, it takes some effort. In modern society, hard pen emphasizes practicality, while brush emphasizes artistry. Hard pen writing is helpful for writing brush. Without the foundation of brush, the common problems are floating characters, thin characters and lack of traditional charm.
The effective method is: find one or several favorite copybooks, read them often when you have nothing to do (so-called reading stickers), choose one copybook and stick to it for 20 minutes every day (hard pen and brush). It was a little difficult at first, but it was still considerable to stick to it. Breaking through difficult words can achieve the goal of writing beautiful and handsome words. (Of course, it is still far from calligraphers.)
Persistence is the most important thing. Practicing calligraphy means practicing heart and perseverance! Be careful. Be patient!
