Chinese New Year has begun!

Around the world, 1.5 billion people - that's nearly a fifth of everybody - are expected to celebrate two weeks of festivities that begin on February 16.

And in China, the Lunar New Year, or Spring Festival, sees hundreds of millions of rural migrant workers that spend most of the year living in major cities travel home to spend time with loved ones.

Together they will make nearly 3 billion trips in a little over a month. It is the largest annual human migration on Earth.

Here's what it has looked like so far this year.
