For many Chinese people, the Spring Festival travel rush means much more than just a migration. At the end of a year, millions of people are eventually able to return to their homes and have a reunion with their families.

But for those who work for railway departments, the Spring Festival travel rush is a battle. Hu Ruichou is a conductor of Xi'an Railway Bureau, who has worked in Spring Festival travel rush six years in a row. The attendants he leads are quite young, with the average age of 23. "We run four round trips a day from Xi'an to Baoji. This year we still will be spending the first two days of the lunar year on the train," said Hu.
