An ancient poem about the origin and customs of Hanlu’s name

The origin of cold dew

Every year around October 8 (October 8th to 9th), when the sun moves to 195 degrees longitude, it is the cold dew of the twenty-four solar terms. "Cold dew" means that the temperature during this period is lower than that during "white dew", and the dew on the ground is colder and is about to condense into frost. Historical records record that "the cold dew on Dou Zhi Han Jia is cold dew. At this time, the dew is cold and will condense, so it is called cold dew." "Collection of the Seventy-two Hours of the Moon Order": "On the ninth day of the ninth month, the dew will be cold and will condense." "If the "Bai Lu" solar term marks the transition from hot to cool, the heat has not completely dissipated, and dewdrops can be seen shining brightly in the morning. Then the "Cold Dew" solar term is a symbol of cooler weather, marking the transition from cool to cold weather, with dewdrops shining coldly, as the saying goes, "Cold dew, cold dew, cold dew everywhere."

From climatology, we know that after the cold dew, the cold air in the north has a certain influence. Most areas of our country are under the control of cold high pressure, and the rainy season has ended. The weather is often warm during the day, cool at night, and the sky is clear, giving it a late autumn scene. In normal years, the 10°C isotherm has moved south to the Qinling Mountains and the Huaihe River line at this time, and the temperature generally drops below 0°C north of the Great Wall. In most years in the capital Beijing, the first frost can be seen at this time. Except for the Qinghai-Tibet Plateau, where snow falls all year round, snow has generally begun to fall in the Northeast and northern Xinjiang. Thunderstorms have disappeared in most areas of mainland my country, and thunder can still be heard in parts of Yunnan, Sichuan and Guizhou. The precipitation in October in North China is generally only half or less than that in September, while in northwest China it is only a few millimeters to more than 20 millimeters. Drought and lack of rainfall often bring difficulties to the timely sowing of winter wheat and become one of the main limiting factors for high yields of dryland wheat. In ancient my country, cold dew was divided into three periods: "The first period is when swan geese come to visit; the second period is when the birds are clams in the flood water; the third period is when chrysanthemums have yellow flowers." In this solar term, swan geese form a line or a herringbone formation and migrate south in large numbers; in late autumn, During the cold weather, the birds disappeared. The ancients saw many clams suddenly appearing on the beach, and the stripes and colors of the shells were very similar to those of birds, so they thought they were transformed by birds; the "Chrysanthemum Shi Huanghua" in the third period is It is said that chrysanthemums are generally in bloom at this time.

Quietly,

Watching the autumn light.

The evening scene is desolate,

It makes Song Yu sad.

The water is gentle and the wind is gentle, the apple blossoms are growing old,

the moon is cold and the dew is cold, and the phoenix leaves are turning yellow.

Redeem love and hurt.

Where is the old friend?

The smoke and water are vast.

Unforgettable.

Wen’s wine party,

a few lonely moons,

times turning into stars and frost.

The sea is vast and the mountains are far away,

I don’t know where Xiaoxiang is!

It is difficult to rely on distant faith when thinking of two swallows,

It refers to dusk The consciousness of sky and sky returns.

Looking at each other sadly.

In the sound of broken Hong,

The setting sun rises.

On August 19th, Meng Chongqing of the Examination Court

Wang Anshi

Autumn is long in the empty court, and I am worried about my clothes at dusk.

Noisy people's chatter has become the city, and the day has not yet arrived among the hibiscus trees.

The love you always cherished has become a dream, and the color of jade is like a happy face.

After knowing the opposite, we should no longer be separated, chatting and laughing about the moon phase and leisurely.

Picture of a defeated lotus wagtail

Tang Yin

The flying call, walking and shaking are in urgent need, and Noda wants to form a group.

Mo Yan has brothers all over the world, but his flesh and blood are now looking at him with cold eyes.

Lu Zhong sent Lu Shijun back to Zhengzhou

Han Hong

Jinluo rode in the city and went out to send farewell to Shen Dongyang.

September is white, autumn grass is yellow.

Qi Yu listens wonderfully, and Lu wine is fragrant.

If you get drunk and go with a whip, the road to Meishan is long.

Send Xiao Li on the sea

Duguji

The early wind cuts the plug grass, and the knot grows day and night.

Traveling to Yingxi, I returned to Sishengtwilight Festival.

The post building can be seen thousands of miles away, and the head is extended to look at Liaojie.

The distant sea enters the wilderness, and poverty grows in the plain and barren land.

The old country is dreaming, and the old friends are crossing over.

It is a wind-blocking period, and the rain is gone quickly.

Haixi Wangjingkou, the two places are at the end of each other.

I live in the autumn, and then I know the moon with a smile.

Looking towards the south of the sun, all I can see is that the birds are extinguished.

How to soothe hunger and thirst when information is not easily available.

Jie Yuyuan

Huangfu Ran

It is the autumn breeze to chant the round fan.

Things pass every time, and kindness never comes again.

Zao Hong heard about Shangyuan and went down to the deep palace.

The color fades every year, but the appearance is not as good as the work.

The Kiazhou Hostel pays homage to Dr. Wei of Suzhou (there is a ruler book on the official website, and he has longed to leave his hometown)

Linghu Village

Confucianism, study and politics , so he became a mortal child.

If you are ordered to return to the east and return to the west, what is the feeling of a foreign land?

Be generous and grateful, and dare to escape from fame.

I envy those farmers and my relatives and friends.

Autumn has entered the country, and the vegetation has withered and flourished.

The square pond is condensed, and the travel manager is cool and cool.

Yi Jiao guarded Soochow, dreaming of hearing praises.

The clouds and rivers are vast, but it is normal to be away from worries.
