Pillow wrist is a way to write with your wrist on the table or on the back of your left hand. There is also a kind of bamboo piece called "handrail" for letting go, which is usually used in summer, because it is easy to sweat in summer, and the sweat on your hands is easy to wet the paper. Pillow-wrist brush calligraphy is suitable for writing small characters or one-inch square middle characters because the wrist is leaning on the table, but it is difficult to move because the wrist is dead. If you write bigger words, you have to write by hanging your wrist.
Hanging the wrist (when writing with a brush)
Hanging the wrist is a writing method in which the wrist holding the pen is suspended, leaving the table and the elbow arm is still leaning on the table. In this way, the range of motion of the wrist is larger than that of the pillow wrist method, and the arm and elbow joint are still leaning on the table, which is relatively stable, and you can write in block letters of two or three inches. Write couplets or broken Chinese characters by hanging your elbow.
Hanging the wrist (when writing with a brush)
Hanging elbow is a method of writing brush characters with all pen holding arms suspended. This method is the best way to write, no matter whether it is big or small, it can be used freely without any obstacles. It is also a common method used by calligraphers. Miti, a great calligrapher in the Song Dynasty, even used the elbow hanging method to write fine print, which shows his deep skill. Of course, novices don't have to do this.
