This young Chinese girl is listening to a whisper along the Echo Wall in the Temple of Heaven in Beijing, China. The Echo Wall is a circular wall surrounding the Imperial Vault of Heaven. It is approximately 12 feet tall and has a diameter of about 200 feet. It gets its name from its accoustical properties -- a whisper spoken on one side can be clearly heard on the other.
