I'm going with the 1979 date, though three places I've looked all have different release years for this movie- 1978, 1979 and 1983. the month and day is the same.
this jerk goes around from town to town "teaching" kung fu practitioners how to "improve" their techniques. he's really good, but that's his only reason.
Mar Lo directed the movie, so it's not as bloody as some Shaws, nor as well choreographed as some others. it's interesting in that regard, as it doesn't look like a Chang Cheh or Lau Ka-Leung movie. the main fault is the story, in that it's not well fleshed out.
of course, I don't care for monkey style kung fu at all, so that doesn't help on a personal level. but it's a good way to spend 94 minutes or so.
