Why don't many calligraphers raise their hands when writing fine print now?

Easy to get tired, etc. If the palm of your hand stands up, the wrist muscles will be bound and in a tense and stiff state. Not only is it easy to get tired, but it is also inconvenient to lift your wrist, especially when writing big characters. So now many calligraphers don't raise their palms when writing fine print. If you stand and write with your palm, you can't stand up at all. Therefore, we don't think it is necessary to keep the palm upright, but it is appropriate for the palm to form a 45 angle with the paper.
