Tens of thousands of passengers were left stranded at a railway station in southern China's Guangzhou region, after a rare snow storm in central China delayed train services at the height of travel during the annual Lunar New Year .
State broadcaster CCTV said over 80 trains were delayed at Guangzhou Railway station Monday, as huge crowds of anxious travelers lined up outside the station.
As many as 3,000 police officers and security guards were deployed to the station to maintain order. Many of those traveling are migrant worker returning to their homes in rural China from their jobs in the nation's manufacturing hub of Guangzhou.
Chinese travelers are expected to make 2.9 billion trips during the 40-day period, which began on January 21, and is often referred to as the world's largest annual human migration.
