In order to further implement the epidemic prevention and control measures and cooperate with the epidemic prevention and control work of local governments, the railway department has decided to temporarily adjust the pre-sale period of railway tickets to 5 days (including the same day) from April 7, 2022, and the recovery time will be notified separately. At the same time, the transportation capacity will be dynamically and flexibly arranged according to the ticket purchase situation of passengers, so as to accurately meet the travel needs of passengers.
