Hey, Meghan

There is just only one train K70/K67 from Qingdao to JDZ. it's need 25 hours and 47 minutes. The ticket price for the Hard Seat is RMB198. The ticket price for the Hard Sleepr is RMB361.
I suggest that you could taka the train K1136/K1137 from Qingdao to Jiujiang. it's need 18 hours. Jiujiang is a city nearby JDZ. The ticket price for the Hard Seat is RMB137. The ticket price for the Hard Sleepr is RMB317. After you arrival in Jiujiang around 12:00. You could take a High speed bus from Jiujiang to JDZ, it's need another 2 hours. the price for the high speed bus is around RMB70.
Or please take a plane from Qingdao airport to Nanchang airport. There are 5 planes every day. I suggest that you could take the plane CA3585. THis plane will depart from Qingdao at 12:40, and arriva in Nanchang at 14:15. The ticket price is about RMB700. There are many high speed bus from Nanchang airport to JDZ everyday.
