With Shanghai still cleaning up after the heavy snowfall, at least 10 mainland airports were closed on the second day of the Lunar New Year transport crunch because of the cold weather.
Shanghai media reported that the city was recovering from days of snowstorms that were the strongest in two years.
On Thursday, more than 500 flights were delayed at Pudong and Hongqiao airports, stranding more than 10,000 passengers.
And 500 long-distance buses were prevented from leaving Shanghai after sections of the highway were covered by snow.
Low temperatures pushed electricity consumption in the city to a record high, Xinhua reported, while the media said the prices of vegetables increased by 50 to 100 per cent.
Shanghai's transport authorities activated an emergency contingency plan to clean up snow piled on icy roads, keeping the traffic flow normal within the city.
Flights departing from Shanghai were gradually returning to normal after the snow stopped yesterday.
