Practice directly by writing brush? Yes, a hard pen and a writing brush are the same. The strokes, dynamics and shelf structure are all the same. It is that regular script is somewhat different from running script or running script in stroke order. For example, on the right side of the bead, the third stroke in regular script is horizontal, and the third stroke in running script is vertical. Just to write faster.

You don't have to find and buy, you can practice your favorite font from the material world. There are more than 40 fonts. You can also write your own words seriously, from the website of "China Natural History"? Look it up in the sub-column of Chinese Dictionary. The real Cao Li seal script is owned by famous artists in ancient and modern times.

I'll send you a picture by the way. It's time to rest.
