As the icy temperatures and snowfall experienced in the Chinese capital and other locations started to lessen, Beijing experienced its longest cold wave since records have been kept in 1951.

For the first time in several days, the temperature at Beijing’s Nanjiao weather station increased to above zero degrees Celsius on Sunday afternoon, according to Beijing Daily, the official state media.

Beijing Daily reported that “Since temperature first dropped to below zero degrees on Dec. 11, the temperature had remained below that line for more than 300 hours,” 

Henan, a province in central China, has experienced numerous system breakdowns.

A malfunction at the Wanfang power plant on Friday caused a partial shutdown of the heating system in the city of Jiaozuo. The city’s official newspaper, Jiaozuo Daily, states that the issue was resolved on Saturday and that heating is anticipated to start up again on Sunday night.

According to statements from the governments of Puyang and Pingdingshan, two other cities in the province, “prioritize limited heating resources for hospitals, schools, and residential buildings” by turning off the heat in the majority of government buildings and state-owned businesses since Friday.

Beijing’s metro system is having problems as a result of the cold weather that started a few days ago in the capital.

When two trains collided on a busy metro line in Beijing earlier this month in snowy conditions, hundreds of commuters—many of whom had fractured bones—were sent to the hospital, according to the city’s transportation officials.

Following a fatal earthquake in northwest Gansu province this month, rescue efforts were further impeded by the bitter cold.
