Hi, anyone know how to travel to Lianyungang from Singapore?

It seems that there is no direct flights from Singapore to Lianyungang. I read from somewhere that we can transit at Shanghai Airport or Nanjing Airport. Which route is nearer and more convenient? I understand that Liangyungang can be reached by train and bus. If via train or bus, how long is the journey from Nanjing or Shanghai? Thank you.
