（t is short for tourist, s is short for sally）

t: excuse me, i am a tourist from new delhi（新德里）。 can you tell me the way to sun yat-sen memorial hall?

s: well, the place where you want to go is far from here, you'd better catch the no.2 bus, and get off at the third stations; sun yat-sen memorial hall is in front of you. you can't miss it.

t: but where the bus-stops?

s: go down this road, turn left at the first crossing, and then go straight, you’ll find the bus-stops.

t: thank you very much!
