Patrick: Dongchuan used to be a very famous spot for copper mining and this has been the case since the Ming Dynasty. At the time there was even no roads. It was like the tea horse. It was the copper road. This road was going from Dongchuan to Yibin and then going to the Yangtze to take the Great canal to go to Beijing with the copper from Dongchuan. It was very famous because the emperors were using this copper, also to make the coins they were used in the time. This copper history is something which is very unique. I think we can do a lot around this. I take the example of what happened in southern Belgium Wallonia. This used to be places very famous for mining of coal and steel and now all this industrial spots, they are converted into museum or special places to do photography, or you can even go in some mines which are kept. You can see what the miners did. It's incredible, you go very deep in the ground by lifts and I think we can do this in Dongchuang as well. I think there is still a possibility to bring back old industrial sites to explain about this history.
