Judging from this sentence, your calligraphy skills may not be very deep. Although my calligraphy is average, I know it's only been three years and I haven't studied it specially. Maybe everything is just a scratch. Learning calligraphy, especially at the beginning, requires specialization. Just look at the calligraphy of famous artists.

If you write according to your own experience and feelings, it is unlikely to teach students well. I think it is better not to mislead others.
