Narrative:

Landing rollout at zgsz runway 16 almost turned off at notamed closed taxiway E6. Closed taxiway E6 was identified and briefed however during landing rollout I started to turn off on E6 but was warned by ATC at about same time that we discovered error. Aircraft never entered closed taxiway as we corrected and exited runway 16 via E7. What led to confusion: 1. High work load post landing (first officer was flying) 2. Commercial chart efb moving map display selected but aircraft position indication not present. 3. Poor taxiway signage; turnoff sign for E7 (next taxiway) is located very close to taxiway E6. 4. No barriers or other indicators at closed taxiway. 5. Light weight landing with subsequent short rollout. Efb moving map correctly indicated E6 closed but aircraft position was not present. Question: is the aircraft present position (pp) indication designed to appear at a certain ground speed? Had the position indicator been present; I would have instantly noted current position and not have been confused by E7 sign. In the future I will not clear runway until efb moving map pp indication is available to confirm my actual position. I will also attempt to pick a reference point to indicate desired runway exit route other than rely on signage. Especially in china.

Title: An Air Carrier pilot noted that his EFB moving map own ship symbol was not visible after landing and so he nearly exited ZGSZ Runway 15 at Taxiway E6 which was closed. Poor E6 signage location also caused confusion because the sign is near Taxiway E7.
