If i was going to your town which place would you reccommend me to visit?
If you visit Taiwan, I will recommend you to go to the night market and Taipei 101.
Taipei 101 is the tallest building in Taiwan, you can have a wonderful view of the whole Taipei city.
And you can find a lot of delicious food at night market.
Cambodia, Angkor Wat-- one of the top three largest religious monuments in the world!!
In Athens Greece it would be
Acropolis of Athens and the Acropolis Museum.
