Sculpture in middle of ‘Mirror of the Sky’ China lake criticised for disrupting serene beauty China’s Chaka Salt Lake, a heaven-like tourist attraction hailed as a “mirror of the sky”, has hit the headlines over an “ugly” installation. The lake in northwestern China’s Qinghai province is famous for its mirror-like surface, formed as a result of the water’s high salt content. It was selected by an authoritative Chinese geography magazine as being among the top must-visit sites in China and received around 40,000 visitors daily last year.
