Can you nail the paper to the wall to write when practicing brush writing?

People often say that characters are afraid of going to the wall, that is to say, once regular script is pasted on the wall, it is easier to reveal weaknesses, so beginners often paste their own characters on the wall, which makes it easier to reflect and find out the gaps. However, when practicing calligraphy, you must first sit at the table, such as sitting posture, holding a pen, lifting and pressing, turning around, stumbling and so on. These basic rules of writing posts must be practiced by sitting down, and it is a long-term sit-in job. After three or five years, when your wrist strength, elbow strength and arm strength have begun to take shape, you can naturally write on the wall. There is no shortcut to calligraphy. You'd better watch Mr. Tian's lecture.
