The Spring Festival, or lunar new year, is China's most important holiday for family reunions. According to The Ministry of Transportation, around 258 million train trips are estimated to be made during this year's Spring Festival, which runs from January 16 to February 24.

China's news website iFeng.com shows images of people sleeping on the ground of the train stations while waiting for the train. Most of them are migrant workers who can't afford a hotel.
