The station has left luggage facilities either staffed (at the right hand end of the station as you look at it) or in lockers in several places, including the soft class waiting lounge. You will need a ticket to gain entry to the soft-class area first though.
The taxi rank is down under the station (escalators in the middle of the concourse).
It is a very easy station for departures and arrivals, although, needless to say, the hard-class method is incredibly crowded.
All signs are bilingual.
If you speak Chinese, there is an advance booking ticket office opposite the northern end of the station on the corner. This can be quicker than the main ticket office at the weekend.
