Winter freeze generates heated debate

Traditionally, central heating has only been available to people in the north of China, but as climate change prompts lower temperatures nationwide, there are growing calls for its use to be extended to the south. Cang Wei reports from Nanjing.

Although his parents are expecting him to return to his hometown for Spring Festival, China's most important festival for family reunions, Liu Yueting has decided not to go, despite not having seen his parents for six months.

"It's all because of my little girl. Our 2-year-old traveled from Beijing to Nanjing with us last Spring Festival. Although my parents' house has air conditioners, she caught a bad cold because of the lack of central heating," the 35-year-old said.
