Hi. There are bullet trains between Nanjing and Shanghai. The fare is 93 or 112RMB per person. BUllet train is the fatest and most comfortable way to reach Shanghai from Nanjing. You can also take bus at Nanjing Zhongyangmeng Bus Station.
As to the flight, I think you can choose either Hong Kong or Shanghai.

Many Thanx for the info
Is there bullet train from Nanjing to Bejing? If yes, what is the travel time and fare per person

Cheers
