A: How is your trip?

B: Perfect. I visited Lhasa, a pure city where I can image I were in heaven. Potala is a must-see. All in all, I was impressed by different cuilture, different sights and different food.

B: Seven days. I wanted to stay there longer, but holiday was over. So I definitly will go there again.
