Need help with title for 2 movies

Both of these I watched when I was 10 in the early 80's on Kung Fu Theatre.

First movie: there's this traveler with some invincible arms that would chop up swords. The Man with the Golden Arms or something but all I can find if The Kid with the Golden Arms. That's not the one.

Second Movie: there's this young guy who gets into trouble in China, stows away on a ship to the US, goes to Chinatown, works as a dishwasher. slept on a super high bunk bed, gets beaten up by local gang. He then learns martial arts, gets rich, etc. For some reason, I liked that movie.

Thanks much!
