How should teachers improve their calligraphy?

Teachers should have perseverance and perseverance when practicing calligraphy. After all, "haste makes waste". As a teacher, I still have time to practice writing for half an hour every day. You don't need to practice calmly every day. As long as you write carefully, you will have some experience in a month or so. Practice calligraphy for a month, and then compare the original characters with the current ones, and you will see progress and have more confidence in practicing calligraphy.
