Why is China's calligraphy the art of stippling?

Judging from the shallowness of calligraphy, to pursue the texture of lines, points are the basis of calligraphy, just like bricks are to architecture; Lines are made up of points. When the brush falls on the paper, it forms dots first, and then it is transported into a line. The person who is good at calligraphy lies in brushwork, that is, brushwork. So it can be said that it is the art of stippling, hehe, my humble opinion.
