It seems like it is normal in Shanghai for the temperature to rise or plummet 10-15 degrees in a single day. Today the sun is shining and all the cold of yesterday and the days before is gone. It's +15 suddenly! Still it can go either way from here so I'm not packing my warm clothes away quite yet. Yesterday evening I went to eat with some friends and we had to run cause it was so cold. Today we were sitting in the park enjoying the sun for the first time. I hope this lasts and I can start exploring Shanghai even more now that I don't have to worry about freezing.
