He said the ministry would not mark up discount ticket prices either. Experts believed it meant discount prices for new air-conditioned trains, as well as most of the latest high-speed trains, would remain and there would be no temporary rise during the peak season.

China had long adopted the practice of offering discount tickets for students to ensure they could go home for vacation at less expense.

The MOR had offered round-trip tickets for migrants this year. Previously, the tickets were only available to students.

China also boosted its rail speed for the sixth time in April, along with the launch of trains that ran at speeds of up to 250 kilometers per hour.

The operation of such high-speed trains was expected to help to handle the travel peak more efficiently, as it could shorten travel hours.
