At first, copy a single pen, then copy the words, pay attention to the configuration of other people's words and the charm of strokes, then copy a paragraph of text and learn the position and shape of other people's words in the whole article. Don't copy it if it feels almost the same. Take a piece of white paper and write it yourself, and then compare it with the copybook to see what you have not learned well, so that you can remember it deeply. I used to practice calligraphy like this, and my handwriting is ok, but now, like you, I have used the computer for a long time and my handwriting has not improved.
What I said is just imitating other people's copybooks, which is enough for us ordinary people. Good imitation is also good writing. If you want to write a good word with your own characteristics, you have to read more famous copybooks and study one of your own characteristics. You still need unremitting efforts, hehe. ...
I wish the landlord success
