Chinese Hand Signs.

No one really stops to think about it, but body language can vary significantly from place to place - even from something as simple as counting. Here, they have a one-hand system of counting from 1 to 10.

When asking one of the pedicab/rickshaw drivers if he could take us to our dorm, he responded with a "six" sign, to which I met with a bewildered stare - I thought he was making a rude gesture at me. From what one of the Chinese volunteers + the internet has told me, there are at least three signs for 7, as well as 10. The 7 pictured above is closest, but from what I've seen here, it is actually more like 9 - but with the pinky.
