This week, China’s north including capital Beijing, its surrounding Hebei and Tianjin, Henan, Inner Mongolia, and northeastern provinces Liaoning and Heilongjiang have logged historically their coldest temperatures for the middle of December.

In Beijing, city authorities rushed to fix a leak in a thermal pipe network that supplies heating to buildings in central Dongcheng district.
