The southern section of the Shanghai Expo Culture Park, which opened at the end of September, has already become a crowd magnet. With a huge greenhouse and two artificial hills, the park aims to bring nature back to the shining business city. The twin hills (双子山 Shuāngzǐ Shān) in particular are a source of excitement and head-shaking. Their hollow structures house exhibition halls, parking lots and even a substation. Chinese travel review portals already ironically advertise a small waterfall on their slopes as „China’s Niagara Falls.“
