1. The travel time for student tickets is limited to June 1 to September 30 during summer vacation and January 1 to March 31 during winter vacation. That is, starting on January 1st.

2. This adjustment of the pre-sale period does not involve high-speed trains and special trains, and the window is still 10 days. The sales start time is 9:00 am. That means you can buy tickets for the 29th tomorrow morning; if you call, you can buy it 11 days in advance
