On Sunday as we were wrapping it up she mentioned she was a long time practitioner of both Bau Gua (Spelling?) and Chi Quong.
You are right. There are lots of other ways people spell it too: PaKua, Pa Qua, PaQua, Ba Gua, BaGua, Ba Gwa, or BaGwa, Bāguàzhǎng, etc
That would be a demo I would enjoy watching. I have only done a tiny, tiny bit once during a day seminar my teacher did for our dojo.
