The train from Dalian to Changchun

The fastest train is t5307, which leaves at 10: 07 in the evening and arrives in Changchun at 5: 55 in the morning after 7 hours and 48 minutes. Sleeper 155- 175 yuan. And there are only two stops (Siping and Gongzhuling). I think this is more suitable. You can also get a discount if you have a student ID card. I don't know the exact discount. Other flights are for reference only.
