Prolonged extreme weather continues to sweep across Central and East China. On Sunday morning, China's National Meteorological Center (NMC) issued four extreme weather warnings, including a blue warning for strong winds, an orange warning for freezing, an orange warning for blizzards, and a yellow warning for dense fog. Due to the impact of extreme weather, a large number of travelers returning home before the Spring Festival have been stranded on their way, and local authorities and departments are actively taking measures to cope with the situation.
