Match the venue, exhibition center and hall on your ticket first, then use a map for the general route to a station and exit. The nearest station or a map pin does not identify the actual event gate. Follow the organizer's notice and on-site signs for the gate, queue location and crowd controls.
These are separate venue facts; event-specific entry and transport rules may change. Follow the organizer's instructions at the event.
