Zhang Yi listens to the audiobook at the Germany Pavilion in the World Expo Park in Shanghai, east China, May 6, 2010.

After queuing for almost an hour, Zhang Yi, a girl from southwest China's Sichuan Province, finally entered the Germany Pavilion. It was the fifth pavilion she visited in the World Expo Park.

"This place is fantastic, like walking in a real city," walking in the different areas of the Germany Pavilion, Zhang Yi said, "each area is a part of the integrated whole city in which visitors could fit in as if they are there in person."

Zhang Yi, born in 1989, is now a junior in Bloomington, Indiana University. She flew back to Shanghai to visit the World Expo with her parents who came from Sichuan, the second day she finished her semester.

"Before visiting here, I thought this pavilion would be filled with exhibits of high-tech, as Germany is an advanced industrial country. After I came, I was attracted more by the humanistic and cultural elements shown here."

"Multi-Generation Centers here represented the endeavor and intelligence when the German people are trying to solve problem of the aged tendency of population," said Zhang, "China is also confronted with such problem, on which we should pay more concern."
