The most important thing in copying is to pay attention to observation and study where there are pens. Why do you bend like this?
Anyway, it has something to do with where they are put. Pay attention to how the people in officialdom put them, so that the whole looks good.
If you don't practice much in a day, you must study, so that the written words will make progress.
I practiced Pang Zhonghua's handwriting and wrote it in a week.
Write slowly, and you will look more and more like it.
Then write your own style.
