the shooting location of 'The Golden Flowers' by Mr Zhang Yi Mou

I have travel plan to take a cruise on Yantze River from Chongqing to Yichang or from Yichang to Chongqing, in mid October. I'd like to travel to the shooting location of above Chinese movie. I'm sure it's at Wulong but I have half day only before going back to Chongqing. I'd ask whether the building complex (in the movie) is located at Three Natural Bridges or Lotus Cave or Houping Giant Dotline.
How many hours will a mini-van reach to Wulong from Chongqing?
Any suggestion, please advise. Thank you.
