What do you think is the most important thing to learn calligraphy?

The most important thing in learning calligraphy is a solid foundation and profound cultural background. Strictly speaking, learning calligraphy is actually very difficult. If a person writes for the sake of writing, he can't write well. In addition, copying is one of the most ideal and effective ways to learn calligraphy. By copying my own copybook for millions of times, I remember the calligrapher's "three methods (brushwork, calligraphy and composition)" embodied in the copybook in my heart, hold it in my own hands, embody it in my own words, and finally fix it into my own things.
