What does the hidden front in the brush copybook mean?

"Hidden front" refers to the beginning and end of the pen, and "reverse front" refers to the initial state of the pen. This process is what we often call "reverse reentry front", and the ancients attached great importance to the problem of reverse reentry front. The so-called "no drooping, no shrinking, no closing" that Mi Fei said means that the strokes should be reversed and reversed. The so-called "three-fold pen" is also a form of reverse stroke. The function of anti-rightness: First, make the beginning and end of strokes complete and powerful. On the contrary, strokes are easy to come and go like matches on fire, and the strength cannot be expressed. Starting and closing the pen can fully show the strength of the pen and the sense of relief, and the strokes written are thick and solid. Reverse strokes require a pen in the center, while eccentricity lacks relief and strength. The second is to make the stroke have a posture by going back. Swing the pen towards the front, turn the pen to dunk or squat down and return to the front. There will be all kinds of pen mark postures when walking back and forth. The length of the rotation pause is different from the size of the pen tip, and the exposed front or hidden front has different shapes. Important strokes of a word, such as vertical painting in the middle, long horizontal painting, long left stroke, pressing, etc. , is the most needed or most worthy of attention. Because these strokes are an important part of a word, the posture, strength and relief shown in these places affect the morphological beauty of the whole word. Of course, when some calligraphers write horizontal paintings in the middle, they also use the previous strokes. For example, the horizontal paintings of European characters and Zhao characters are often in front, which is also a gesture of strokes.
