Thanks for the detailed report on Changsha's weather. I suppose the winter cold is exacerbated in one's apartment by the lack of central heating, as there's none in South China. I wouldn't mind cold weather outside in winter if I were inside my apartment sat next to a radiator. I think I'll avoid any prospective employer anywhere south of the Yangtze on the grounds of no central heating available there. But in North China, I'm told it's there, and provided free of charge to foreign teachers; that's good.
