The ancients wrote books with big breasts and wide sleeves. When writing, they usually cantilever with sleeves. One is to avoid ink stains on the sleeves, and the other is to hang the wrist wide open and close during the writing process, making the written works pale, powerful and sharp, and "penetrating the back of the paper". There are many ways to practice wrist strength. For example, some people use Tai Chi beads, while others use their arms to hold things. This method is unrestricted and suitable for everyone!
