You think it’s bad, try other parts of the world. Government offices in China are heated by a centralised system. The !st of November is the day and then it goes on. No thermostats, all the radiators are on at full bore. The demarcation line is the Yangtze River, south of that there is no heating, north of it you get the lot. A major industrial city called Wuhan, a combination of Wuzhou and Hankou, straddles the Yangtze, (remember the run of HMS Amethyst down the Yangtze in 1949), has this problem. You go to a government office in one side of the river and they are poncing about in shorts and on the other side they are all wearing overcoats.
