Knowing calligraphy (hard pen)

1\ Hard-pen calligraphy is basically the same as regular script, but the font is different, so it is difficult to show it in brushwork.

You need to pay attention to the font structure, which is not obvious when using a pen. No matter how similar the structure is, it doesn't matter whether you use regular script or official script.

Hard pen calligraphy should be written horizontally from left to right in principle, not vertically.
