We're flying into Zhangjiajie HeHua airport from Shanghai, but on the way back, we'd like to visit Lushan & Huangshan before arring back into Shanghai.

Is it easier to go from Zhangjiajie-> Wuhan-> Jiujiang-> Lushan, or Zhangjiajie-> Changsha-> Nanchang-> Lushan? Would that be bus/ train/ both?

Many thanks.
