Bajiquan

Is Bajiquan considered to be an internal martial art? I’ve always thought of it as an internal system but some people (B.K.Frantzis) describe it as an internal/external system. If this is the case then so is Xingyiquan surely?

I’ve also heard that originally Baji and Bagua were the same art and that they separated. I don’t know how true this is as I believe the “ba” relates to different things. Does anyone have any comments about this?

Any information anyone?

Many thanks,
