P.S. Please be careful when you're scaling some parts of the Wall.... because there aren't any steps at all! It can be very treacherous... and definitely not for the faint-hearted or those suffering from Vertigo.
Before I move on to the next landmark monument, would you like to try and guess how wide is the smallest width of the Great Wall?
What's your prize for guessing correctly? Why, a special pat on the shoulder!
The answer is 40cm, which means only one person can stand on top of it at any given time! This section of the Wall is located at the Shi-ma-tai portion of the mighty Great Wall, 120 km away from the city of Beijing.
I dare you to take on the challenge of standing on a 40 cm wide platform on top of a ridge! More pics of us scaling the Great Wall coming up.... (after I manage to scan my pics).
