But I still feel very cold, biting cold, because the south is wet, so the winter in the south is cold and wet. People often think that southerners go to the north, but they don't think that the north is too cold.

2. The relative humidity in the south aggravates the chill, which is called wet cold. Anyone who has studied physics knows that because the thermal conductivity of water is relatively large, humid air is more conducive to heat conduction, so people will feel that wet cold is much colder than dry cold.
