After starting, the first step is to suggest that you don't write in red (that is, print) first, but copy first, then take a piece of paper and write according to the copybook. Write slowly, stroke by stroke, no hurry ~ after a while, when you feel that you have made progress, paint it red again. After repetition, your handwriting will be improved.
In addition, when you are free, you should observe and think more, look at the words on the billboard and other things around you, and gesticulate at the air or the palm of your hand, which is also helpful to improve the words.
I have been practicing calligraphy since I was five years old, so I have summed up some experiences, hoping to help you.
