Smiles without borders

Dou Li, a security volunteer at the Olympic Village, worked long hours and often missed precious sleep. She nevertheless always flashed a beautiful smile, even after a long night shift. "That's because a smile is the common language of the world," explains Dou. "The volunteers' smiles are the best name cards of Beijing."

Dou was one of 80 Olym-pic volunteers selected from Shanxi province. She graduated this summer from Shanxi Finance and Economics University with a master's degree.

Her journey to the Olympics started seven years ago.
