What is the format of hard pen calligraphy? Write regular script. Write Su Shi's Huanxisha and demonstrate it. How can I sign it?

The format of China's calligraphy is the same, and there is no difference between a hard pen and a brush.

Generally, it is vertical, with the front paragraph written on the left line, the signature written on the right line and the text written in the middle lines. The font of the preceding paragraph and the inscription should be different from the text. If the text is regular script, the inscription and postscript are suitable for running script.
