This winter, for the first time, I have seen such a wide range of rain and snow forecasts: all 34 provincial-level administrative regions in the country have fallen, without exception. Unlike the previous snow in the south, this time the snow is mainly in the north, especially in Beijing-Tianjin-Hebei, there may be multiple rounds of snowfall, the first round starts from the 12th, the duration is still very long, need to pay close attention!
