The "Dry Brush" (kěbǐ) technique is essential in Xieyi, involving minimal ink and water to create broken, scratchy lines that add texture, depth, a sense of age, and dynamism, requiring a sensitive hand and enhancing the spontaneity and expressiveness of the art form.
Key techniques in Xieyi painting include line drawing, splashing ink (Pomo), dry brush work, the control of ink washes, and the strategic use of negative space, each contributing to the expressive power of the artwork.
