1, winter solstice-Du Fu.

I'm a guest all year round, and I'm worried about killing people! Jiang Shang described me as a lonely old man, and the custom of Horizon is self-dating. After the snow, the staff came to Danhe, and the Jade Dynasty came to disperse Chen Zi. My heart is broken at this time, where can I see Sanqin?

2. "I miss my home on the solstice in winter"-Bai Juyi.

Every winter solstice, I am accompanied by the shadow in front of the knee lamp. If you want to sit at home late at night, you should also talk about travelers.

Jia Zi pushes a snowy day, but thorns are still green and flowers bloom naturally. Hehe has been ploughing for a long time, and Yanzhou is rainy and dew.

Historical sources of solar terms:

In ancient China, the sundial was measured by earth gauge, and the longest sundial was defined as "solstice" (also called the day from full day to day, long day to day, and winter solstice), and the shortest sundial was "short day to day" (also called short day to day and summer solstice). One day in spring and autumn is the same length of day and night, which is designated as "vernal equinox" and "autumnal equinox".

There were only four solar terms in Shang dynasty, but it developed to eight in Zhou dynasty and was completely established in Qin and Han dynasties. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. The naming of the twenty-four solar terms reflects three seasons, phenology and climate changes. Beginning of spring, Spring Equinox, Long Summer, Solstice, beginning of autumn, Autumn Equinox, beginning of winter and Solstice are also called eight o'clock.
