China's New Year Holiday Travel Includes Passing Pop Quiz

In China, getting a ticket home for the Lunar New Year can feel a bit like winning the lottery. First, there’s competition for plane, train and other passenger seats for almost 3 billion voyages. Then there’s the quiz to prove you’re not a Web robot.
