In short, there are many calligraphy theory, who are learned, use pens, and so on. They have learned theory and enriched their talents, that is, they have "skills". As for personal cultivation, it is not only reflected in treating people and things, but also in calligraphy creation. That is the Tao.
Copying is the same copybook, but the creation is completely different. Why? Because of different cultivation, different understanding of calligraphy and nature, different pursuit of style.
Only by combining "skill" with "Tao" can we leave outstanding works.
