Ensuring a happy new year for China's poorest people

Groups of volunteers are using their leisure time to book train tickets online and help migrant workers return home for the nation's most important holiday. Hou Liqiang reports.

Instead of preparing for end-of-year exams, Zhao Hongli, a freshman at Inner Mongolia Agricultural University in Hohot, the capital of the Inner Mongolia autonomous region, spent his time on something less interesting, but equally tough - buying train tickets for about 100 migrant workers so they could get home for Spring Festival, the most important holiday for family reunions.

Although many tech-savvy people are familiar with the process of buying tickets via the internet or mobile apps, it can be a baffling experience for migrant workers, many of whom have only received a basic education.
