Introduction
On the Chinese lunar calendar, “Autumn Equinox” is the beginning of autumn and thisday is just at the middle point between “Autumn Begins” to “Hoar-Frost Falls”. After“Autumn Equinox”, the temperature decreases obviously, just like the old proverbsamong the farmers, “Each autumn rain makes it’s colder”, “The night of White Dewsand Autumn Equinox, one night is colder than the one before”. It arrives on September22 to September 23 each year when the sun reaches the celestial longitude of 180degrees. As said in the ancient Chinese books, “the Autumn Equinox” shows the Yin Qiand Yang Qi are half and half on this day”. This means the day and night are balancedand the heat and the cold are even. There is no polar day or polar night happening onthis day on every corner of the world. In some part of the north-east China, it’s notstrange to see frost at this time. The differences between the temperature in themorning and in the night are increasing, to more than 10 degree Celsius. The amountof rainfall decreases and it’s getting drier and drier in the air.
