When you start writing, you can hide the front or show the front. The strokes are steady, which can be changed from heavy to light and then from light to heavy, and the middle can be slightly arched. When the pen is closed, it usually goes back to the front, and the whole horizontal painting will be left low and right high.
Short horizontal is light and short horizontal, which can be exposed, thick or short, and can be written as left sharp horizontal or right sharp horizontal.
When a great calligrapher writes, whether it's hard-pen regular script, running script or calligraphy, he basically has the same technique, that is, brushwork.
Why pause? The main purpose is to create a "rhythm point". If you don't stop, the strokes you write will be straight or have no sense of rhythm.
