Relief

This autumn is particularly cold, Ye Sheng stood at the door and looked at the continuous autumn rain in front of the door and began to worry, because from a historical point of view, it was the beginning of the Xiaoice River period, from the north to the difficult getting colder and colder, in addition, he found the first benefit of a person who crossed himself, that is, all the information he had seen in his previous life was remembered in his mind, as long as he called, he could easily know the future things, and any information that could be collected in his previous life would automatically appear in his mind, such as now others look Ye Sheng in a daze, But in fact, the information of the Xiaoice period of the Song Dynasty, the third Xiaoice period, is appearing in his mind

The second year of Yongxi reign of Taizong of the Northern Song Dynasty to the third year of Shaoxi of Guangzong of the Southern Song Dynasty was the third cold period.

Since the second year of Emperor Taizong of the Northern Song Dynasty (985 AD), the climate has turned cold again, and the strange cold scene of ice and snow in the Jianghuai area has reappeared, and the third Xiaoice in 5,000 years invaded China, and all the citrus and other fruit trees that can be planted in Chang'an, Luoyang, and Tang Dynasty have frozen to death, and the Huaihe River Basin, Jiangnan, the lower reaches of the Yangtze River and Taihu Lake have all been completely frozen, and cars and horses can pass on the frozen river. See the following climatic records, distribution of flora and fauna, and geographical landscapes to get an idea of how cold China's climate was after the middle of Taizong of the Northern Song Dynasty.

◎ Climate records and pollen fossil research: In the winter of the second year of Taizong Yongxi, Nankang Jun said: Heavy rain and snow, the ice of the great river, the chariot and horse can be measured, and the heavy load can be victorious. In September of the first year of Chunhua in the Northern Song Dynasty (990 AD), heavy snow in Jingzhao Mansion damaged the seedlings. In the winter of the third year of Taizong Zhidao (997 AD), there was heavy rain and snow in the south of the Yangtze River, and the Yangtze River was icy. Yanbei magazine volume: Dongting Lake is a business owner who grows oranges, and its benefits are related to agricultural acres. In the first year of Song Zhenghe (1111), there was heavy snow in winter, and the snow was more than a foot, the river was full of ice, and all oranges were frozen to death. In the Ming Dynasty, he was paid for it." In April of the first year of Qinzong Jingkang (1126 AD), it rained heavily in Beijing and the weather was cold. Heavy rains from May to June hurt wheat, and summer and autumn are in season. In the first month of the second year of Jingkang, it snowed heavily and the weather was very cold. The ice is like a mirror, the walker can't stand, many people freeze to death, and the north wind in April is very cold. At that time, it was recorded that there were more than 600 kinds of frozen local chronicles in the Yangtze River Basin, such as Dongting Lake and Poyang Lake, Huaihe River Basin, Jiangnan and other places, which can be described as a wonder of ice and snow. The Yangtze River and the Huai River are not frozen today, and scientists have studied pollen fossils, and it is estimated that the temperature at that time was about 1.0-1.5 degrees Celsius lower than it is now. In the article on the Change of Climate in Chinese History, Zhu Rongfang counted 45 snowfalls in late spring in Hangzhou during the 133 years of the first year of Gaozong Shaoxing in the Southern Song Dynasty (1131-1264), and if compared with the last snowfall in Hangzhou today, the time of freezing in the early Southern Song Dynasty was about two weeks earlier. As for the Southern Song Dynasty, where the drought was the least and the precipitation was the highest, Zhu believes that it may be due to the southward movement of extratropical cyclonic storms and the increase in the number of sunspots.

◎ Distribution of flora and fauna. At the beginning of the Northern Song Dynasty, the tropical animal that originally operated in Kaifeng, Henan Province and Central China, the elephant gradually moved southward due to the colder climate, and after the end of the Northern Song Dynasty, the elephant no longer existed in the Central Plains and the Yangtze River Basin, but was limited to South China. Rice needs a warm and rainy environment to grow. Before the Han Dynasty, the Yellow River Basin in the arid Central Plains of North China was warm and rainy, and there was rice production, but after the Eastern Han Dynasty, the weather became colder, and the rice in the Yellow River Basin gradually decreased. It can be seen that the cold climate in ancient times made rice no longer grow. Zhu Xi of the Southern Song Dynasty commented on the poem of Tang Feng Bustard Feather: "Rice, the rice eaten in the south, is aquatic and white." If there was still rice cultivation in the north at that time, Zhu Xi would not have made such an annotation. Bamboo and rice also need a high temperature and rainy environment, before the Han Dynasty, there were many bamboos in the north, the distribution was quite extensive, but the temperature was low, the production of bamboo gradually decreased, to the end of the Northern Song Dynasty, the output was less, Mengxi pen talk has mentioned: "Yanjun has no bamboo", "and not all the local products". It can be seen that there were very few bamboos in northern China at that time, which should also be related to climate change.

◎ Changes in the geographical landscape. According to the literature, during the Southern Song Dynasty, the mountains in the Sairam Nor region of Xinjiang were covered with ice and snow all year round, but today they are green grasslands, so it can be known that the climate of the Southern Song Dynasty is even colder than today.

Suddenly, a cold wind blew, and Ye Sheng, who was in a daze, woke up in such a daze, and the old man Sima Guang didn't know what was going on in the county seat, so he decided to go out to see the teacher, and by the way, to see what new things were in the county seat of the Song Dynasty. Thinking of this, it was actually like walking in the inner house, and in the inner house, Shen Qingjun was directing the maids to be busy gesturing the yard to repair the sewers and houses damaged by the rain for days. He walked in front of him and looked at Shen Qingjun and said, "Madam, I'm going to go to the county seat to see the teacher," Shen Qingjun glanced at me and said, "Husband, wait, prepare something for the old man in this weather, and Husband will go again." "After saying that, I got up and went out to prepare, and I waited for the next person to finish preparing and then rushed to the county seat by car.

The most unbearable thing in autumn is the continuous autumn rain, miles and miles, there is no end, the cold is uncomfortable, the tide is annoying, and the clothes and quilts are always not dry, and even the mood is extreme. But with a caring student, the situation is completely different.

Ye Sheng had already sent a well-made pig iron stove to the teacher, burning silver silk carbon, and there was no smoke at all. On top of the stove was a pig iron kettle, bubbling.

Sima Guang smiled and picked up the iron kettle, poured the hot water into the pottery pot that had been around for a long time, unhurried, the best tea leaves kept tumbling inside, the faint fragrance of tea permeated the room, and the movement of flowing water was pleasing to the eye.

Opposite Sima Guang, sat a handsome man with a straight body and bright eyes, with a long three-strand beard, fluttering, and only wearing a single coat on his body, as if he was not afraid of the cold.
