Practice horizontal and vertical centering. The key is to keep the pen steady, keep the pen tip in the middle of the stroke, make the lines full and powerful, and experience the feeling of "drawing sand with a cone".
At the beginning, practice at one speed and one length. At first, don't be too long. After basically finding the feeling, slowly try to practice at different speeds and lengths. No matter how long and fast the speed is, the center and pen should be stable, impartial, full and powerful and not erratic.
2. Practice of horizontal and vertical lifting.
Practice of horizontal and vertical lifting. This is much more difficult than the last line of practice. The key is to add sharp in and sharp out. However, we should also find the feeling of "drawing sand with an awl" and keep the pen tip running in the middle. The biggest difference is that the pen is not round, but sharp, and it should be realized by moving in the air.
You can also change the position of the taper, such as one-side taper or middle taper. As shown above. The lines can also be oblique and cross left and right, which is very helpful for canceling and holding paintings in the future.
3. Practice in circles
Practice of circle. Keep the pen tip in the middle of the stroke. The purpose of circle training is to practice pen rotation. Learn to turn the pen tip with your fingers and wrists when turning. The purpose is, of course, to keep the pen in the center.
You can also practice S-shaped or arc-shaped deformation lines. The length is also from short to long, and the speed is also from slow to fast, but we must always keep steady and steady, full of strength and not weak.
As the saying goes, if you don't practice writing, you get nothing. Basic skills are always the core and most important of calligraphy, otherwise the written words are like passive water. These three exercises should be concentrated for at least one month. Practice for half an hour every day, and then keep practicing these basic lines, just as a violinist always practices scales for an hour or two when practicing a specific piece.
