The characteristics of hard pen calligraphy are 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 pen is mainly a pen, the lines are much thinner than the brush, so the font is much smaller, even smaller than the fine print of the brush; Thirdly, due to the material of the pen, the hard pen is easier to control than the brush.
