Hundreds of tiny dolls made of fabric climb up and down a wall hanging at the entrance hall of Shanghai World Financial Center, Oct 24, 2011. The dolls, forming two streams of tiny people, illustrate a scene of people rushing to work. "Go Up and Down Mountain" attracted a lot of white collar workers and visitors. The exhibition is part of a series of art shows held by Shanghai World Financial Center to celebrate the third anniversary of its founding.[Photo/CFP]
