英语说节气丨关于秋分，你一定要知道的8个小知识！
秋分是中国传统二十四节气（the 24 traditional Chinese solar terms）中的第十六个节气。“秋分”的英文表达为Autumn Equinox，它有以下两个含义：
平分秋季：秋分是秋季的中点，将秋天一分为二。
平分昼夜：这天太阳几乎直射地球赤道，各地昼夜等长。
After that day, the location of direct sunlight moves to the south, making days shorter and nights longer in the northern hemisphere.
秋分过后，太阳直射点向南移动，北半球白昼时间变短，夜晚时间变长。
中国典籍《春秋繁露》记载：“秋分者，阴阳相半也，故昼夜均而寒暑平。”
"It is on the Autumn Equinox day that the Yin and Yang are in a balance of power. Thus the day and night are of equal length, and so are the cold and hot weather."
秋分的到来，预示着这一年已脱离夏的炎热，正式进入了秋季。秋分有哪些特点和习俗呢？一起看看吧。
cool autumn
秋渐凉
As it is said in the ancient book, The Detailed Records of the Spring and Autumn Period (770-476BC), "It is on the Autumn Equinox day that the Yin and Yang are in a balance of power. Thus the day and night are of equal length, and so are the cold and hot weather."
据古书《春秋繁露》(公元前 770 到 476 年)记载：秋分者，阴阳相伴也，故昼夜均而寒暑平。
Since the Autumn Equinox, most of the areas in China have entered the cool autumn. When the cold air southward meets the declining warm and wet air, precipitation is the result. The temperature also drops frequently.
秋分以后，中国大部地区进入凉秋。南下的冷空气与逐渐衰减的暖湿空气相遇，产生降雨。气温也频频下降。

Eating Amaranth
吃秋菜
In South China, there is a custom popularly known as "having Qiucai (autumn vegetable) on the Autumn Equinox day". Qiucai is a kind of wild amaranth. Every Autumn Equinox day, all the villagers go to pick Qiucai in the wild. Qiucai is verdant in the field, thin, and about 20 cm in length.
中国南方，逢秋分有 “吃秋菜” 的习俗。秋菜是一种野苋菜。每到秋分这天，全村人都去野外采摘秋菜，这时田野里的青菜碧绿纤瘦，约 20 公分高。
Qiucai is taken back and made into soup with fish, named "Qiutang" (autumn soup). There is a verse about the soup: "Drink the soup to clear the liver and intestines, thus the whole family will be safe and healthy".
秋菜采回家，与鱼片煮汤，名曰：秋汤。关于秋汤，还有一首打油诗：秋汤灌脏，洗涤肝肠。阖家老少，平安健康。

Season for enjoying
osmanthus 品桂香
The Autumn Equinox is the time for smelling the fragrance of osmanthus. At this time, it is hot in the day and cool in the night in South China, so people have to wear a single layer when it is hot, and lined clothing when it is cool. This period is named "Guihuazheng" in Chinese, which means osmanthus mugginess.
秋分，桂花飘香，闻芳美时。这个时候的南方，日暖夜凉，因此白天穿单衣，晚间就得加件衣裳。这个时期，也谓之为 “桂花蒸”，意为桂花绽放之时，出现的闷热天气。
Season for
enjoying chrysanthemums
赏菊花
It is also a good season to enjoy chrysanthemums in full blossom around Autumn Equinox.
秋分前后，正是菊花盛放时，赏菊品香好时节。
Standing eggs on end
竖鸡蛋
On Autumn Equinox day, there are thousands of people in the world trying to make eggs stand on end. This Chinese custom has become the world’s game.
秋分这天，世界各地成千上万的人在做竖蛋试验。这种中国习俗已成为世界游戏。
According to experts, on the Spring Equinox and Autumn Equinox, the day and night are of equal time both in the southern and northern hemispheres. The earth’s axis, on its 66.5 degree tilt, is in a relative balance of power with the earth’s orbit around the sun. Thus it is a very conducive time for standing eggs on end.
据专家介绍，春分、秋分当日，南、北半球日夜均等。呈 66.5 度倾斜的地轴与地球日公转的轨道平面处于一种力的相对平衡状态，因此，有助于鸡蛋竖立起来。
But some also say that standing the egg has nothing to do with the time. The most important thing is to shift the egg‘s center of gravity to the lowest part of the egg. In this way, the trick is holding the egg until the yolk sinks as much as possible. For this, you’re better off choosing an egg that’s about 4 or 5 days old, whose yolk is inclined to sink down.
但也有人认为能否竖蛋与秋分无关。最关键的是要把鸡蛋重心下移。如此一来，只有蛋黄尽可能下沉，才能完成这个恶作剧了。竖蛋时候，最好选择刚出生 4、5 天的鸡蛋，这样的鸡蛋蛋黄下沉，重心下降，更有利于竖蛋的成功。
Sacrificing to the moon
祭秋月
Originally, the festival of sacrificing to the moon was set on the Autumnal Equinox day. According to historical records, as early as the Zhou Dynasty (c. 11th century-256BC), the ancient kings by custom sacrificed to the sun on the Spring Equinox, and to the moon on the Autumn Equinox.
原本祭月节是设定在秋分这天的。据史实记载，早在周朝（公元前 11 世纪至 256 年），古代君王便依照习俗于春分祭日，秋分祭月。
But since it is not a fixed day in lunar August, there might be no full moon on the Autumnal Equinox. During the festival, if there was no moon to make sacrifices to, it would spoil the fun. Thus, the day was changed to the Mid-Autumn Day.
但因每年农历八月，这一天并不固定，秋分当日并不一定都出现圆月，而祭月若无月，则大煞风景，故而，将祭月节由秋分改为中秋举行。
