Write it all at once in three steps: start, do and close.
1. Start writing: enter sideways, then adjust the front (that is, you say "turning the pen", which is actually the rotation of the pen tip, without turning the pen holder, the effect you want to achieve is to change the force from the lower right to the right) and adjust it to the right center.
2, line pen: that is, spread the brush (bristles) to the right.
3, pen collection: return to the correct pen state (return to the state before writing, the pen is straight and straight).
What are these actions for? They are used for writing and writing. Tilt in, then lift the pen to the right, and the pen will spread out and you can write. Otherwise, how do you write the right side if you go in sideways?
As for how to use force, I'll teach you one of the most stupid but practical methods-filling ink with double hooks, covering the strokes with thin paper, marking the outlines with thin lines, and then trying to fill them with a brush. The simplest and most direct way is to use the correct brushwork. As for how to push hard and how to raise a pen, you can experience it yourself and choose the most scientific method to use it.
Can be used for reference: Analysis of the brushwork of Teacher Song Li's Zhang Menglong Tablet.
In the absence of a teacher, you can only do this, fill in the ink repeatedly, and then compare it with the original post.
