In writing, it can be divided into hidden front and exposed front; (Qi Ming Publishing House: That is to say, the hidden front and the exposed front usually appear at the beginning of a stroke, and you can feel them when you look at the picture later. ) in line strokes, it can be divided into center and flank; In terms of pen collection, it can be divided into convergence and release.
As we all know, when writing with a brush, the human hand is the driving force and the brush is the tool. Just like a lever, there is a problem of an arm and a fulcrum. If you find the right fulcrum, you can set the length of the arm of force. If you know the length of the arm of force, you can know the space range of writing with a pen.
When the writing fulcrum is determined, the spatial range of writing action depends on the length of the arm of force.
(1) When the wrist is the fulcrum, the spatial range of writing action depends on the length of the finger (pillow wrist writing).
(2) When the elbow is the fulcrum, the spatial range of writing action depends on the length of the forearm. (written on pillows and elbows)
(3) With the shoulder as the fulcrum, the spatial range of writing action depends on the length of the whole arm (elbow-hanging writing).
In any case, the writing action of holding the pen is limited in a certain space, not an absolute and infinite free space-the fulcrum "binds" the brush!
The fulcrum is tied to the brush. In this limited range of motion space, when you start to write some pictures, you must have an action of stretching out and taking back. Without this back-and-forth action, you can't write a stippling. So "I want to be right and the pen is left first (horizontal), I want to be down and the pen is up first (vertical), I want to be left down and the pen is right up first (left), I want to be right down and the pen is left up first (press)".
The pen tip drops the paper from the air to see if the entry point falls inside or outside the stroke. The paper entry point is in the stroke, which is a hidden front, and the paper entry point is outside the stippling, which is an exposed front.
I don't know how to put many pictures in at the same time. For a detailed explanation of Tibetan front and exposed front, please refer to this article "What is Tibetan front? What is a dew front? (Detailed description of hidden front and exposed front, with attached drawings) "
