Tips for fighting cold
1. If you want to keep yourself warm, go to a corner (of walls), as it is about 90 degrees;
2. But it would be warmer if you lie on the floor, because it is 180 degrees;
3. If you want to be even warmer, rotate yourself for one cycle, it is 360 degrees;
4. If you still feel cold, go and look for him/her among crowds, for it is over 1000 degrees there as a famous poem told us.
