This is the first scientific explanation of the echo phenomenon of the buildings in the Temple of Heaven. Sanyinshi is located on the ramp in front of the imperial palace. Standing at Sanyinshi, you can hear three echoes, which is called the whispering of the world. The meaning of the words and deeds of the world are seen by the angels.
