From Nanfengchuang (in Chinese), translated by EastSouthWestNorth:
Upon understanding, when the film crew of The Promise led by Chen Kaige arrived, Shangri La county thought that they have a terrific promotional opportunity and they discussed if the sets from The Promise such as the Flowery Golden House could be left behind for the purpose of developing tourism to the Bigu lake.
But the best intentions of the local government were not realized. Instead they are faced with the embarrassing situation in which the natural view of the lake was destroyed. According to information, there have been many movie and television crews shooting in Shangri La, and most of them paid attention to issues of trash clean-ups afterwards — what to clean themselves and what to hire others to clean. The ravishing of the Bigu lake with no one paying attention afterwards for more a year seems to be a unique instance.
“We welcome more friends, but we don’t want the beautiful Shangri La to become the garbage dump of the visiting guests. We will treat the affair of The Promise as a lesson,” said a local government official.
