First of all, ① write vertically, usually vertically, but with a slightly curved pen, the intensity is slightly light to heavy;
Secondly, ② vertical folding, vertical folding slightly to the right, strokes should not exceed the midpoint of ① vertical in the horizontal direction, that is, they should not exceed the midpoint of a vertical, which is as high or as short as the midpoint. On the left and right sides of ① vertical, the length of right folding should be basically equal, and the strength of strokes should be basically uniform until the folding is finished, and the strokes will recover slightly after the folding;
In the last 3 vertical strokes, the pen should not exceed the midpoint of 1 vertical in the horizontal direction, or slightly downward, and the force is basically uniform.
