To learn to hang your elbow, practice hanging your wrist first. Beginners will encounter the problem that their hands will tremble, so they must study hard and persevere. There are two ways: one is to hold the pen tube upside down in your spare time, or take a chopstick, hold it according to the correct writing method, hang your wrist and circle around the table. After a period of practice, your wrist will gradually stabilize. The other is that when writing, the left hand is placed flat on the desktop and the right wrist is placed on the back of the left hand. After a long time, the left hand can be detached and the right hand can be stabilized. These two methods can be used at the same time, and you can get the effect after practicing for a period of time.
When we are practicing brush calligraphy, in the primary stage, because we are completely unfamiliar with the performance of the brush, we can first write two or three inches long regular script by hanging our wrists. After a period of practice, we have a little grasp of brushwork, and our hands are getting used to it, so we can practice hanging our elbows. Of course, suddenly all the arms are suspended, and there will be some difficulties at first, and my hands will be sore. As long as you insist, it will be solved. Fast is a week, slow is a month. If you are afraid of pain at first, or look at the handwriting that is not as good as when you were resting on your wrist before, you still put your arm back on the desktop, and you may not be able to hang your arm for life.
