On the 20th, Beijing ushered in the first snowfall in the Year of the Dragon. Snowfall coincides with Beijing's evening rush hour, which has a greater impact on traffic.

Beijing is under a blue warning of cold wave, with low temperatures and a cold feeling. In response to the cooling weather, the Beijing Urban Management Committee has issued a "warming order" to ensure the quality of heating during the cooling period. It is expected that by 17:00 on the 21st, the surface temperature will be below 0°C.
