Pointing is like falling rocks, but it is as real as collapse; Horizontal painting is like a thousand miles of clouds, but it is tangible; Vertical paintings are like long live withered vines; Draw a picture like a rhinoceros; Painting is like breaking waves, and the sound is like thunder; Inclined hook is like a hundred bows; Crossfolded crossbow tendons; Every word is as wonderful as its shape, and the book is finished.
The pen is long, the snake is long, and the wood is three points.
