If you have to choose one, then choose Tian Yingzhang.

Tian Yingzhang, a teacher in Beijing, has a deep foundation.

As a predecessor of calligraphy, he began to publish copybooks and monographs as early as 1980s, which failed to catch up. Tian Yingzhang's hard pen calligraphy is basically the form of his brush calligraphy, which is very similar to the brush calligraphy in stroke structure and composition.

I think Tian Yingzhang's hard pen is the deformation of his brush. His brush is dignified and beautiful, and his hard pen writing has the same characteristics.

Compared with hard pen calligraphy, Jing's hard pen calligraphy is another style. Tian Yingzhang's hard-pen calligraphy is different from Jing's. This is the biggest difference between their hard-pen calligraphy, and the structure is similar.
