I suggest you pay attention to the following points: 1. The starting stroke should be light and the writing stroke should be strong, forming a small triangle.
2. The vertical part should be vertically downward and cannot be tilted. In standard hard-pen block letters, the vertical axis is vertical, but in actual writing, in order to make the characters beautiful, they can be slightly tilted or slightly curved.
3. The lifting part should be slightly heavier when starting, then gradually become thinner, and finally the closing part should be strong.
4. The connection between vertical and lifting should be natural and form a whole.
