Is Xu Mulan a true Buddhist?

Xu Mulan is not a Buddhist. Although I have never met her, I feel that she is a living bodhisattva, and no one can meet a living bodhisattva.

I just saw a netizen say that listening to classics should be learned from famous teachers. I don't think so. I think learning from famous teachers is not necessarily wise, but it is not necessarily as practical as ordinary people.
