The way to write a book is to be able to open it and save it. If you can't do these two things in writing, it's like staying up all night, which is crooked ways.
In other words, being able to put down and hold back is a way that is respected by China people, and it also requires the writer to have strong control over the pen.
"Existence", also known as "Qi", is the accumulation of strength before a horse jumps. Using this metaphor, "saving the pen" means using the pen before each stroke, which requires high strength and speed.
Mi Fei's Shu Su Tie and Tiaoxi in Song Dynasty, and Mi Fei's "You" and "Guo" are more and more powerful, regardless of their length.
"Drive" means that the horse suddenly stops to turn. "Grabbing the pen" is continuous with the previous stroke in direction, but it turns immediately after stopping the pen quickly, with short strokes and coherent breath, which is also a high-tech action.
The word "province" and "tomb" selected by Wang Xizhi in Jin Dynasty, the word "ambition" in Preface to Lanting and the word "province" in Mourning Post are often really subtle.
Because words are like people, what can be released can't be closed, and what can be closed can't be released. It is rare that both can be made into excellent works.
As the pen moves freely, learners should not only improve their skills, but also cultivate their minds. This is a process of blending heart and pen.
