Flamingo sculptures, elegant curves of bright red metal, similar to iron anchors, have been interpreted in Chinese as flamingos, stable, firm and elegant, standing on the square of the Canton Federal Building in front of the tall steel and glass skyscrapers, and have now become a landmark of Chicago. This is the work of American artist Alexander Calder, 16 meters high. This sculpture has a peculiar shape and a high artistic imagination. At noon, the people in the building relax around, and the light and shadow cast by the sculpture are beautiful, accompanied by the high-rise buildings around her.
