Be a man. Do the right thing.

Today I've came across to this Chinese saying, "be a man, do the right thing" ( n make sure u pronounce it in Chinese slang for originality). I think I've heard of it somewhere before this, but I can't remember when and where. It just sounds so familiar and interesting!

I'm not sure what is that right thing to do, maybe any Chinese friends can advise me on that..hehee.. but I like it. I mean, it advises u in your action.

and this video seems to be a hit for this saying. do enjoy as I am ^^
