Soldier:My friend，do you know how to get the FAO？
Stranger:FAO？
Soldier:The Food and Agriculture Organization？
Stranger:Ok，I see.It’s just beyond that tall building.
Soldier:How do we get there？
Stranger:Go along this street，and 200m turn left at the second cross，and then you’ll see a blue gate.That’s it！
Soldier:It doesn’t seem that easy！
Stranger:Let me get in，and I’ll take you there.
Soldier:No，thanks！I think we can make it.
