Here I found some funny pictures about the Beijing 2008 Olympic Games. The first is how the waitress are trained to smile. As we can see, everyone one is taking a pencil in her mouth. Thus to make sure that only 8 teeth are shown to the others.

The second one here seems to be a "balance training". Everyone is taking a book on her head and keep it there. As we can see from this picture, even when having a book on head, they are smiling so sweet ;)

Anyway, I don't quite understand how to explain this picture in English properly, maybe you can give me some tips?

Then, the last one (Fuwa girls), just for fun:

PS: One more for fun (Fuwa comic version) ;p

FYI: Most of the pictures are originally from club.163.com, some are from xiaonei.com.
