Brian: It's always a very challenging question. It's a difficult challenge to balance economic development and heritage protection. As we grow now in Yunnan and we see how attractive Yunnan is to the world, to the rest of China. We should make sure that in some way we are more careful in the growth. Yunnan will be a destination for the world 100 years from now 200 years. What we need to do is come up with a way that I believe will not forfeit some of the social resources and cultural resources that complement the landscape the scenery. People love Yunnan, and many of us love it in the most simple way the beautiful weather, the beautiful scenery looking at Erhai lake looking at Cangshan mountain. But there's so much more to Yunnan as well and I believe the other aspects of Yunnan the cultural resources the social resources should also be protected and this is something that I know is a difficult balance.
