The heating program in northern China should be expanded to include the south, a political adviser said, Nanfang Daily reported.

Winters in recent years have been particularly cold in southern provinces such as Guangdong and Guizhou, where winters are usually mild compared to the north. Coupled with the humidity, it feels even colder in the south than the north, said the adviser, Zhang Xiaomei.

Currently, the heating program is limited to areas north of the Qinling Mountain-Huaihe River line.
