돌아오다 is coming back, and the -아/어 verb before it says in what state or by what route. 살아 돌아오다, coming back alive, appears twice; 만신창이가 되어 돌아온 is coming back battered; 2천 년을 뛰어넘어 돌아온 유행 is a trend that has come back across two millennia. It also covers money finding its way back to you — 74%가 돌아왔대요 (they got 74% of it back).
