need to travel from shenzhen to guzhen by train, and from guzhen station to guzhen lighting fair.

Direct train for the journey is not available; if transferring, it is troublesome. I suggest you take a direct bus to Guzhen from Shenzhen Bao'an Bus Station or Longgang Long-distance Bus Station. Then catch a cab to the lighting market with the fare of no more than CNY10.
