Changsha's foreign trade is really hard to find, but with the rise of central China in the past two years, it should develop faster. I don't know exactly which new industries have been developed. Although I am from Changsha, I have no special nostalgia for Changsha. The environment in downtown Changsha is not so good. It feels a bit messy and dirty. Consumption is also high, but income is not so good. I hope that Changsha will develop rapidly, like a coastal city, and don't ruin the reputation of the ancient city of Changsha.
