Two people were killed and three injured in collisions which damaged more than 40 vehicles on a section of the expressway linking Harbin, capital of Heilongjiang, to Suihua City on Thursday, due to sudden snowfall, local government sources said.

 

At least 74 inbound and outbound flights were delayed at the Longjia international airport in Changchun, capital of Jilin, due to the snowy weather.

 

Thirty-two flights were forced to land in alternate airports. The airport started a red alert and closed for about three hours before reopening at 6 p.m. Thursday.

 

Most expressways in Jilin and 13 expressways in Liaoning imposed traffic control measures. Some flights were delayed at the Taoxian airport in Shenyang, capital of Liaoning.

 

Spring Festival, or the Lunar New Year, is the most important occasion for Chinese, who have a weeklong holiday period, placing a tremendous strain on railways, airports and expressways.

 

This year's Spring Festival falls on Saturday. About 3 billion trips are expected to be made during "chunyun," the travel rush that lasts this year from Jan. 13 to Feb. 21, the National Development and Reform Commission said.
