When practicing calligraphy, if you write a word many times, you will find it more and more unrecognizable. What is the reason?

Seeing the question answered upstairs, I can directly say that this is a professional question. You haven't practiced calligraphy, and you don't know the three flavors. Just because you haven't heard of it doesn't mean it hasn't happened.

In the process of practicing calligraphy, you encounter problems that everyone will encounter. Because of the attention paid to this word, as well as numerous copies or exercises, this word has lost its impression in the mind, which is what we call progress in chaos. In that case, I hope you will give up this word for a while and practice again. When you write again, you will find that you have improved a lot.
