The Temple of Kung Fu Movies - Looking For a Movie

Can you help me find this film!!!
I have been looking for a kung fu movie for years now but nobody seems to know about it, so now I'm asking all you visitors for better luck.
I had this movie about 4 years ago when I lived in South America so the title may not be the same but it was something like "Heroes of Kung Fu" or "Kung Fu Heroes" but it might've been the Spanish title "Heroes de Kung Fu". I know that there's another movie which goes by that name (Kung Fu Heroes) but I've heard that it's not the same movie. At that time this was my top kung fu flick and one of the first to introduce me to the genre.
I don't know if I might like it as much today but I still would like to have it.
Anyway, It's an old school movie from the 70ties or so, could be the eighties too.
The plot involves a guy that gets beaten up (maybe by the Ching dynasty/manchu people?) and then gets saved by a family that hide him 'til he recovers. He later helps the family by beating up the local rascals who are up to no good, beating, raping and robbing people. The movie takes place in the 1700-1800 or so like most old school movies.
An interesting fact is that the major rascal trains with a venomous cobra, fighting with it (cool stuff!), and he also leaves prints on whatever he hits on. The hero also gets a lot of daggers stuck in him at the end.
That's about all I can remember.

Anyway, I would REALLY appreciate any answer on aka titles, cast, director and anything else on this movie.

Please save this page on your hard drive so you can inform me if you come across it.

Thanks!!!
