Project helps journeys home for holidays

The Spring Festival travel rush in China is dubbed the world's largest annual migration, with more 2.9 billion trips being made as people reunite with families to celebrate the Lunar New Year.

The urge to head home, however, puts a huge strain on public transport, making train tickets from cities to less developed regions some of the most hard-to-get items.

But with this in mind, a non-profit project called Shunfengche is now in its fifth year offering a solution for many.
