Answering queries, punching tickets and collecting used instant noodle containers - the Spring Festival travel rush is always a busy time for the employees of Changchun Railway Station.

Li Qiang, who works at a ticket kiosk, smiles and asks her customer to confirm the details of their booking for the third time.

"It only takes seconds to sell a ticket, but we must do whatever we can to avoid mistakes," said Li. "Ticket changes are difficult during the Spring Festival."
