From Silver Valley to Silver Screen

The Silver Valley is a movie about ancient banking and finance industry in Shanxi (晉) province China http://www.thesilvervalley.com/eng_menu.htm I haven't seen the movie but, the name Silver Valley implies that there is a astonish accumulation of wealth by the "merchants of Shanxi" 晉商. Shanxi is also the wealthiest province in China during both Ming and Chin Dynasty.
