Can we learn from soft pen calligraphy to improve the level of hard pen calligraphy?

I think so, too. I used to write badly. Later, I learned soft pen calligraphy. When I write, I am very happy. At least I know when and where to write tightly and where to write loosely.

But I also think that if you write soft pen calligraphy well, it will be helpful to hard pen calligraphy.

If soft pen calligraphy is useless, do you still expect hard pen calligraphy to improve?

I just want to improve hard pen calligraphy, so I learned soft pen calligraphy.
