I watched it a while back but can't remember the name... it was about some asian girl who dressed up like a boy and was thought to be a boy... she had to escape the local mafia I guess and joined up with an american lad who came to china to get cheap labour because his dad was building a railtrack through a mountain... the girl/boy worked in a firework company in china I think...
I remember some part where she/he had to go into the mountain to plant an explosive and she almost didn't make it out but the dude helped her/he... etc
Can anyone help me out please... thanks
