Armed guards on patrol Shenzhen North Stn.

Admittedly not a clear picture, snatched a quick glimpse of the troop carrier and a group of four armed guards marching back and forth in front of the railway station.

Also, for the first time, elsewhere in the city I've also seen armed security services walking around in pairs in Shenzhen's busier metro stations. Maybe not a good idea to take pictures of these guys.
