In this volume, the center of the pen is straight down, thick and fine, and the pen is written quickly and freely. Especially the movement front, there are rich changes in front, side, hidden and exposed, the stipples have a coherent transition, and the ups and downs of the lift are natural and elegant, without any trace of carving. The structure is comfortable and the middle palace is slightly convergent, maintaining the balance of the center of gravity. At the same time, the long painting is vertical and horizontal, stretching freely, rich in ups and downs. Throughout the text, the font is slightly tilted to the left, with many sideways tendencies, trying to level out the danger. The writing style of the whole volume is sincere, straightforward, lively, varied, and full of interest, which reflects the typical appearance of Mi Fu's middle-aged books.
