Thats why you dont go to Badaling, since that isnt even the original part but something that was kinda "rebuilt" in the 70s.
If you are in Beijing and drive a bit more out, there are still old original parts of the Great Wall that you can climb and hike around. Of course you need to be a bit adventurous. Actually the real "charme" of Beijing is hidden inside the hutongs and smaller parts of the city not many tourists, western and chinese, know.
read about it a few days ago... those bastards destroyed like 90% of their cultural heritage to make room for hotels and touristy places - in short to make even more money.
are they unable to understand the irony in this?
