The soul of calligraphy is the truth of being a man, that is, the world. People who can understand the truth of life and the way of the world need to experience and study. Experience promotes people's awakening, and reading promotes people's thinking. Only by combining the two can they understand the way to be a man.
Handwriting is drawn under the control of thinking, so you can be a man, you can think, and you can think a little about the structural layout of the painting. Appreciators can understand from the handwriting that the soul of calligraphy is here.
