How to practice writing "Si"?

"Si" is written differently in different places. But the baSic essentials of writing "si" are:

1, use a light pen, and some "holding" pens need a little pen, thus forming a small silkworm head at the pen.

2. The pen should be transported steadily, and the pressure should be gradually reduced during the pen transportation, so that the "Si" will gradually become thicker;

The pen is lifted horizontally, so the tail is the tip of the knife.

Personal experience is for reference only.
