The Chinese migrants trying to get into the US

We travel to South America to meet the Chinese migrants who are making their way to the United States using an unexpected route - the established migrant trail through South and Central America to the southern border with Mexico. Citing economic challenges at home - and using inspiration from social media - a growing number are making this perilous trek. Reporter Shawn Yuan travels along the route speaking to migrants about their journey and their aspirations for the future.
