Wen Duyi’s head was throbbing.  Perhaps sleeping out under the stars had been a bad idea. He didn’t mind the fact that he had woken beneath a layer of leaves. It was actually kind of romantic. Communing with nature and all. He didn’t get to do that much in his dorm at DongNan University in Nanjing.

What did disturb him was the thick layer of grey grit covering his skin. Wasn’t it supposed to be dew that fell in the night, not the smog?
