Please identify the authenticity of this qigong calligraphy.

Hello:

My personal opinion is that it is really unlikely.

The focus is on the writing of the word "person", which is obviously wrong.

Qigong's calligraphy: the second stroke of all "people" is obviously different from the second stroke of "people" in this picture you gave.

Only refer to qigong calligraphy.

thank you

I hope I can help you. Please don't be fooled.
