How to write regular script?

The word "book" in calligraphy is written in regular script, as follows:

1. Write horizontal first: from left to right, write a horizontal first, the length is about one third of the width of the whole word.

2. Write a vertical row again: from top to bottom, write a vertical row, which is twice as long as the horizontal row.

3. Write again: write oblique strokes from top to bottom, which is about half the length of the vertical line.

4. Finally, write: write a stroke obliquely from bottom to top, the length is the same as the length on the left, and the intersection with the horizontal is in the center of the vertical.

It should be noted that the writing of Shu in regular script can be adjusted according to personal style, but the original proportion and structure of the whole font should be preserved. If you want to write a perfect regular script, you still need to practice more.
