From Ningbo want to go to Longquan City, Zhejiang Province by train or bus. Details please.

There is no direct train service. You can take a coach to Longquan from Passenger Transport Center located at No. 181, Tongda Road, Yinzhou District.
The buses are scheduled at 9:00, 12:20, and 17:00. The trip takes about 6 hours. The fare is about CNY 145 per person.

Thanks Amy for your prompt reply. I am really happy for your guidance. Can you pl send me the NB Bus terminal address in Chinese for going to Longquan please.
Can you purchase bus ticket for 18th May, 2016 at 9am bus for us. How to pay you? Thanks

The bus station is located at No.181, Tongda Road, Yinzhou District. And the name in Chinese is '宁波客运中心'.
In addition, the official booking website doesn't have English version. You can ask the hotel staff to help you. Or just arrive the bus station early and purchase the tickets there.

Thank you for your support.
Regards
