Set a goal before writing a copybook, such as writing exactly the same words on the copybook. There are two things to remember when practicing calligraphy: radical and structure. Buy a copybook you like and practice slowly. Of course, it's best to keep practicing until you get it.
You can copy copybooks at first. After practicing for a period of time, if you don't think you will get much, you can change it to copying, and then you can feel that your handwriting has improved obviously. Because copying a post is like drawing a gourd ladle, it's easy to get distracted without bothering, and it's hard to find shortcomings, while copying a post requires full attention, so it's easier to find your own shortcomings.
Practice commonly used Chinese characters first, and the words must be written in big letters. The purpose of practicing calligraphy is to be able to apply it in life. Many words can be written at that time, but if they are not used for a long time, they will be forgotten when they are written, and practice will not have any effect. Writing commonly used words is conducive to strengthening memory. The words are bigger, the structure is clear at a glance, and the details can be seen more clearly.
