  Wu Weiyang is a Junior 3 student at the High School Attached to Beijing

University of Chemical Technology. He has been a fan of photography since

primary school, so he takes his camera to school every day. In the early morning

of March 18, 2007, on his way to school, Wu Weiyang saw the morning sunlight

shine on the Bird's Nest. It was very beautiful. He took out his camera and took a

snapshot (快照) of the scene. From then on, photographing the Bird’s Nest had

become one of his habits. He takes one picture every day. So far, he has taken

more than 300 pictures of it." I am lucky because where I live is an excellent

spot for photos of the Bird’s Nest," says Wu. "I can take pictures whenever I

want." His school collects Wu’s photos. The series (系列) is called "The

Footprints (脚印) of the Olympics." Wu had a wish. On August 8, 2008, the

Nest all day." I took pictures from sunrise till sunset, until the Olympic torch
