What is hard pen calligraphy? What I wrote below, success in a horse, is this called hard pen calligraphy?

Hard pen calligraphy is mainly compared with brush calligraphy. First, because the material of the hard pen tip is relatively hard, its line changes are not as soft as those of the soft pen-the brush changes greatly; Second, because the commonly used hard pens are mainly pens, ballpoint pens and pencils. The lines are much more delicate than the brush, so the font is much smaller, even smaller than the fine print of the brush; Third, due to the material of the pen, the hard pen is easier to control than the brush.
