Who is the highest level of calligraphy in ancient and modern times? Wang Xizhi, of course. Otherwise, how can you say that Wang Xizhi is a "book saint"? The brush in the hand of a clever calligrapher is a sword. Wang Xizhi uses a pen, and his best skill is profiling, especially sharpening! Looking at Wang Xizhi's ink, we can know that his pen basically enters the paper horizontally and then becomes the center. Maybe just use the winger.
Here is an example:

Wang Xizhi's ink mark has a small sharp line at the beginning, which turned out to be a cut-in trace. Let's just say that this little sharp point is the first action of the brush into the paper. Its function is to open the brush, or it may be called to press the brush.

Let's take another example: if we enter a room and need to push the door by hand first, then the small tip of the pen is the arm that pushes the door. Then, some people will say that many words in aunt's post are not sharp. Why? I tell you, this is a subtle brushwork, called implication. For example, in Wang Xizhi's "Aunt Post", when you enter the door, you don't open the door by hand, but arch it with your arm. It's called walking through the snow without trace!

Some people think that the Preface to Lanting has not regressed at all, but in fact they don't know why. When learning the preface of Lanting, they always regard the small part of the pen tip as a part of the line, not knowing that it is a prelude, so they learn the shape, but never know what the small pen tip is for. Therefore, without that little sharp corner, it seems that Wang Xizhi is not.
