It can be said that many calligraphers attach importance to a special one. Calligraphy style is the characteristic of soft pen calligraphy, and there is a deep family tradition for soft pen, which makes calligraphy more traditional.
Therefore, we can see that in the copybook written by Tian Yingzhang, the hard pen is a miniature version of the soft pen in a sense, regardless of strokes, structure or layout. Therefore, people who want to learn from Mr. Tian Yingzhang's hard pen always say that they must be cautious. It's difficult to practice without a soft-pen calligraphy foundation, so they need a deep soft-pen foundation.
