I would suggest a change of genre for Legend of the Mountain (1979). It's clearly not a martial arts film, but I don't know what you'd change it to. "Horror" doesn't quite fit, either. Ghost story perhaps?

I was also under the impression it was a Taiwanese film, but I could be wrong there.

It is a Taiwanese film indeed, and not a martial arts film at all. Changed genre to "Historical Drama + Ghost"... hope that fits.

Also added Mandarin as spoken language, and the first paragraph of your review as a plot summary
