You can go there by air or train. If by train, it will take over 24 hour and the ticket price is about 420RMB for hard sleeper and about 650RMB for soft sleeper. You can contact the air ticket office or agency about the ticket price at the day you are leaving. As the data shows recently, the air ticket price is even cheaper then the soft sleeper train ticket and a bit expensive then hard sleeper. For, it needs only 2 hours by air. I do not know which compus do you want to go. If the Jiangjun Road compus, it is not far away from the airport, where you can go by taxi. If the Jiangning Compus, you should take airport bus to Zhonghuamen Bus Station, then change to a taxi.
