Filming location

i searched some chinese webpages and didnt find any information about the filing location.

but in the early part of the film (cant remember maybe ten mins or so), there is a scene that Fugui played huqin which is a traditional chinese instrument and sang a piece of song behind a white screen, and i know this is a traditional art form in shaanxi province. he was also singing in shaanxi dialect. and consider Zhang himself is a shaanxi-nese, he might set the background of the story in shaanxi.
