Passengers get onboard a train at the Chongqing North Railway Station in Chongqing, southwest China, Feb. 20, 2019. China's railways are expected to face the post-holiday travel peak over the next few days when millions of travelers return to their workplaces or schools as the Spring Festival celebration has come to an end. Trains will likely carry 11.04 million passengers on Wednesday, up from 8.72 million on Tuesday, official data showed. Some 930 extra trains will be put into use to meet the travel demand. Hundreds of millions of Chinese went back to their hometowns to celebrate the Spring Festival. The annual travel rush around the festival, known as "chunyun," often puts the country's transportation system to the test. (Xinhua/Wang Quanchao)
