英语学习网站中国铁路官方微博11日发布消息，2020年春运火车票于12日开始发售，这意味着一年一度的春运抢票之战拉开序幕。
“春运”，即春节期间的旅客运输（passenger transport during the Spring Festival），是中国特有的文化现象，通常翻译为“Spring Festival travel rush”，也被BBC称为“每年世界上最大规模的人口迁徙（the largest human migration on earth happening annually）”。
随着春节的临近，数以百万计在外务工或学习的人们将返乡与家人团聚。这种长期以来的传统是春运热潮的主要原因（Millions of people working or studying out of their hometowns will be hurrying home to reunite with families as the Chinese New Year (Spring Festival) approaches. This long-held tradition is the main reason for the rush）。
