The Asian calligraphy's brush must be held vertically, inclining neither sideways nor toward one self. To achieve best ergonomics, keep the inside of palm round as if holding a small egg. Keep fingers firm, using fingertips instead of knuckles to hold the brush. Keep the wrist supple, firm, and soft. Level wrist to a more natural and horizontal angle, avoiding strained angles. The technique is called round stroke or upright stroke.
