************************

The weather was crazy yesterday. Windstorm the whole day and night. Apparently, the wind comes from Inner Mongolia. I can still feel the wind in the room even the window is shut. It was so cold. The heater will not work until November. I just have to wear more layers until then. A friend told me that you can buy the plug-in heater for 150 kuai. I will consider getting that if it gets really cold. :D
