This is very good film from Mainland China, film took place in Beijing, and outside city, It was good thriller film, My friends, and family also enjoyed the film, It is many mainland china films that are not known to many outside Mainland China. I really enjoyed everything about the film, It has a very modern atmosphere, And the acting was good, all were upon favour of me. In Beijing this was a popular film, Though it will probably not be known to many countries internationally. If anyone has access to this film outside Mainland China I recommend to see it because you may enjoy this film. It is a wonderful thing to come from Mainland China.
