Some Chinese cities have a system where the domestic heating is controlled by the authorities and comes on for the whole on a fixed date, stays on for three months and then goes off for the whole city on a fixed date. Right now I am sitting in my apartment in an overcoat and have taken my gloves off to type this. A month ago I was sitting in an apartment in T-shirt and shorts with the windows open to let out some of the excessive heat. Great system isn't it?
(In case you were wondering, my apartment has no other heating system and if I plug electric heaters in they blow the fuses!)
