What idioms (words) describe a person's handwriting well?

Spring insects and autumn snakes, strong through the back of paper, flowing clouds, ancient Yan, iron-painted silver hooks, vigorous and powerful, and so on. . . I can't remember many idioms for the time being. . But if there are many ways to describe a person's good handwriting, why do you have to use idioms?
