World's Biggest Annual Migration Underway in China


It's China's great escape. Hundreds of millions of people across China rush home for the Chinese New Year holiday in the biggest human migration on the planet. Beijing's Ministry of Transport expects more than three billion trips, by train, plane and road, will be made over the 40 day travel period. Although most journeys are made by car, the biggest crowds are seen at railway stations like this one. Tickets are always scarce.
