Q: Do train crew members need to be quarantined after they finish a round trip to Hubei?

A: For the safety of service on the train, we conducted nucleic acid tests for 650 attendants who serve on the train travelling passing through Hubei. They are not going to exit the train stops on the route and will move together with the train. So when they are back at places out of Hubei, they are safe and do not need to be quarantined.
