What kind of table should I buy to practice standing? What's your height?

Standing to practice calligraphy, the height of the book case needs to be lower than the waist, and the abdomen can be aligned. If it is too high, it is no different from sitting practice, and it can't achieve the purpose of coordinated practice of legs, waist, arms, wrists, fingers and eyes. And it is difficult to wrap a large paper web. The average person in China is only 80cm tall. If the height is too high or too low, it can be customized as needed. The size of the case depends on personal conditions. Generally speaking, to write a piece of paper more than six feet, the study area is enough, and the bigger the better, so that tools such as pens, ink, paper, inkstones, pots and felt can be put down without embarrassment.
