Who wrote Feng's T-shape on calligraphy and painting?

In calligraphy and painting, who wrote Feng T-shaped? Wen Zhiming is famous for being good at all kinds of calligraphy, especially running script and small letters. But he said: now, when commenting on calligraphy, everyone compares me with Mr. Feng, but we live in different environments. He is in a "remote place" and I live in a "provincial capital metropolis"; If I change places, how can my reputation match him?
