Nice pics, but are you sure you want to go to Canada with all the cold and snow they've been getting.
It's far more comfortable in winter in Canada than in Changsha. In Changsha buildings are built to dissipate heat and there is no central heating, so when it's 0ºC outside it's the same inside and space heaters do nothing unless you are directly in front of them. The cold gets into your bones. You wear long underwear, hats, gloves and jackets inside to watch TV. Outside is ok because you are moving around and it's not that cold. In Canada right now it's -18ºC but I am toasty warm in my house.
