How to modify sick sentences with his handwriting?

If we want to modify the ill sentence of "his handwriting is as dragon as tiger", we should first analyze and compare the semantics and collocation, and then modify it.

"Dragon and Tiger Leap" means flying like a dragon and jumping like a tiger. Describe a person's vigorous movements when running and jumping. Metaphorically speaking, do something. The subject of this sentence is "pen character", which is obviously inappropriate to describe "dragon and tiger leap". "Fly" means to fly like a dragon; Like a phoenix dancing. It can be used to describe the power and flexibility of calligraphy strokes. So we can change "his brushwork is dragon and tiger leaping" to "his brushwork is dragon and phoenix dancing".
