Hello: practice at least one copybook every day (fonts are not limited, it is better to have two fonts). After practice, practice in another book, each word ten times. I've been practicing for a long time now, and it works.
Tip: Don't hold the pen too heavy.
You can write again if you are not satisfied.
If possible, cursive, compare as much as possible after writing a word.
(please accept it, thank you ~)
