Tangshan da xiong (The Big Boss / Fists of Fury) soundtrack name?

This song plays in the original Mandarin version of the movie and was composed by Wang Fu Ling. I just do not know how to obtain a full version of it.
it's in this video (starting at 41 seconds ending at 1 minutes and four seconds)

Ah yes, how amazing of you TO GIVE ME REPUTATION INSTEAD OF ANSWERING MY GAWDAMN QUESTION

I would wager the rep is just standalone encouragement, and probably not offered instead of an answer they have but refuse to tell you.

Ah-HAH! That means it IS somewhere on the interwebz. Now I'll go search for it.

My secret is that I have answers to all questions but I'm just mean and don't want to reveal them.
