The issue with lo wei was several things, I think Bruce just thought he was lazy and Lo didn't like Bruce much either, apparently it got to the point of Bruce pulling a knife which was disputed at the time but his wife, Linda, confirmed it fairly recently.
Bruce was drugged out for a large part of the time in hong kong and he was having issues with the fame too, it's what killed him. That's not the Bruce who lived in Seattle as far as I know.
