How does soft-brush calligraphy develop a fascinating style?

Start at the center of the paper and write against the wind. Write to the right and circle slowly. At this time, we should talk about a very important issue-adjusting the front. When completing lines, the brush must be used by the center. There is basically no difficulty when you are in a straight line, as long as you brush as straight as possible. But it is not so easy to change the direction: the stroke that was originally in the middle of the stroke, after turning the direction, is biased to the side of the stroke, which is what we often call "deviation". So we need to practice how to keep the pen used in the center after changing the direction, that is, "adjusting the front", and drawing mosquito-repellent incense is a good training method, because the brush needs to change the direction constantly when drawing a circle. But I need to practice hard by myself. I have been studying calligraphy for almost ten years, and I really feel very elementary recently.
