Qigong is written in general, why is it so famous?

Qi Gong is a leading figure in contemporary calligraphy, and of course he is famous in contemporary times. Qigong calligraphy has its own system and unique style. It can be named "Qigong Style". Although it is not as good as you said, it is contemporary after all, just like Deng in the Qing Dynasty, whose fame at that time may be greater than now, and his influence will be much smaller after a hundred years of baptism. I think qigong may be "dim" after a hundred years.
