回过头 I am reading a Chinese practice book and I am stuck on the specifics of this sentence: *After the main character is called by a friend* 他回过头一看，有个男的骑自行车过来． I understand that it means something along the lines of: He turned around to give a look, it is a man on a bike coming over. But what is the direct translation of 回过头？ As far as I know, 回=return， 过=go over, and 头=head. What are the specifics?
