What are the three stages of calligraphy copying?

Calligraphy copying can be divided into three stages: face-to-face, face-to-back and face-to-meaning. Face the face, that is to say, put the copybook in front of you, compare it with the face one by one, pursue modeling, restore the content of the copybook as much as possible, and don't add your own style. It's better to do a double. Look back, that is to say, write down what you learned when posting, don't read the post, try to restore it. This is more difficult, it is a transitional process of applying what you have learned, and it is also to better deepen your memory and turn other people's experiences into your own. It means to paste the practiced wordpad and add your own understanding and style characteristics. This is creation.
