冬至日
Winter solstice
是北半球各地一年中
It's a year in the northern hemisphere.
白昼最短的一天。
The shortest day in the day.
过了冬至以后，
After the winter solstice,
太阳直射点逐渐向北移动，
The sun's direct point moves northward.
北半球白天开始逐渐变长，
The northern hemisphere begins to grow gradually in the daytime.
正午太阳高度也逐渐升高。
The sun's height is also rising at noon.
所以，
So,
有俗话说，
There is a saying,
“吃了冬至面，一天长一线。
"Eat the winter solstice, a day long.
“冬至大如年。”
"The winter solstice."
早在二千五百多年前的春秋时代，
As early as more than 2500 years ago in the spring and autumn period,
中国就已经用土圭观测太阳，
China had to observe the sun with tugui,
测定出了冬至，
The winter solstice was measured.
它是二十四节气中最早制订出的一个。
It is one of the earliest twenty-four throttle.
