On our way back from the great wall and the Ming tombs we wanted to have a look at the olympic stadium designed by the swiss architects Herzog & de Meuron. Our taxi man was very kind to show it to us. Btw if you are there to visit try to book him: his name is Tian Chin Yo, his cab is BF5145 and his phone number is 13701174159. We managed to have him for the entire day for 800 RMB (plus the entrance fees and a tip at the end that he was not expecting)
