The ancients in China divided beginning of autumn into three periods: first, waiting for the cool breeze; Second, wait for the white deer to be born; Three are waiting for cicadas to sing.

Then, there will be fog on the ground in the morning, and cicadas will begin to sing in autumn when they feel gloomy.
