We roasted the fire in the snow-white snow house that was as warm as spring, and the red flames were like golden snakes dancing wildly, jumping and dancing unscrupulously in the stove, and constantly sending us warm steaming, and outside was the cold wind of the rampant and raging Arctic, and we talked happily around the fireplace, and it felt very pleasant. Hu Jiaojiao asked curiously, "By the way, apart from us, have anyone else in our Great Song Dynasty ever been to the North Pole?"

Xiao Fei smiled and said: "There should be no more in the Song Dynasty now, but the legend says that Dayu seems to have been, that is, Dayu in the famous Dayu water control story." I read in the book that Dayu in Chinese mythology is not only a hero who governs water for the people, but also an explorer who travels the world. After completing the water control project, Dayu sent the god Taizhang to measure the earth with footsteps. Taizhang walked from the East Pole to the West Pole, and the measured length was 233,500 li and 75 steps. Dayu also sent the god Zhuhai from the North Pole to the South Pole, and measured the earth with a bamboo piece called "calculation" about 6 inches long, and the result was exactly the same as the distance between east and west. It can be seen that the earth where people live should be square, and they are in the center of the square earth surrounded by the four seas, so it is logical to call themselves the central country, that is, China. Later, Dayu went to the horizon to explore and carried out diplomatic activities by the way. He traveled east to Fuso, where the sun rises, to the fields of Jiujin and Qingqiang, and to the country of Toriya, the country of Black Tooth, and the country of Qingqiu, where there are nine-tailed foxes. He went south to Cochin, climbed over the extremely hot Jiuyang Mountain, and arrived at the Feather Country, the Naked Republic and the Immortal Country. I went west to the Sanwei Mountain Country where the Three Blue Birds of the Queen Mother of the West lived, and saw people who only drank dew and did not eat grains; I also went to the gold accumulation mountain full of gold, and saw strange brains and people with one arm and three faces. To the north, he went to Lingzheng and Dog Rong, and then passed through Jishi Mountain, and went to Beihai to visit Yujiang, who was also the god of the sea and the god of wind. After saying goodbye to Yujiang, Dayu planned to go home, but he got lost in the vast wind and snow, but went north more and more, and finally arrived at a place called Zhongbeiguo. This country of the end of the North may be the first and only recorded record of our country's documented expedition to the Arctic. ”

Zeng Lu asked curiously: "Then dare to ask this Arctic ice and snow, the road is far away, how can there be a record in the book? Could it be that the Eskimos themselves wrote it, but they slash and burn and eat raw meat, so primitive, can you understand the works they wrote?"

Xiao Fei continued to say: "Most historians believe that civilized mankind first set their sights on the North Pole from ancient Greece. Because, it is said that the Arctic Circle was first determined by the ancient Greeks. They discovered that the stars in the sky could be divided into two groups, one of which was in the north of the world and could be seen all year round. The other group is located near the zenith and in the south, and they only cycle periodically with the seasons. The dividing line between these two groups of stars is drawn by a circle drawn by the constellation Ursa Major, which happens to be the circle of latitude at 66°33′ north latitude, which is the Arctic Circle. In fact, Pythagoras and his school despised the idea that the earth was square or rectangular, and their philosophical thinking led them to firmly believe that the earth was perfect only if it was spherical, in order to meet the needs of "universal harmony" and "number". And Aristotle, Plato's student, laid the foundation for the concept of the earth. He even considered that in order to balance the large land masses of the northern hemisphere, there should also be a continent in the southern hemisphere. Moreover, in order to avoid the embarrassment of the Earth being top-heavy, causing the North Pole to face downward, the area around the North Pole should be a relatively light ocean. As a result, a Greek named Bizeas bravely pulled up the sails more than 2,000 years ago and began the first attack of civilized mankind into the North Pole. It took him about six years to complete the voyage, reaching as far north as Iceland or central Norway, possibly into the Arctic Circle. In 325 BCE, Bizeas returned to Massella. So it's really glory that belongs to Greece and greatness to Rome. ”

Garfield said puzzledly: "You said that this place is cold and snowy, there is no grass, there is no people, we still have these dry food, canned food, relying on the mountains to eat the mountains, relying on the sea to eat the sea, what do these Eskimos eat, how can they survive?"

Hu Jiaojiao echoed and said: "That's it, I also feel strange, there is nothing here, no animals are seen, there is ice and snow everywhere, do these Eskimos eat ice?"

Duan Gongzi said with a slight smile: "Actually, there are many animals in the Arctic, mainly polar bears, reindeer, wolves, foxes, rabbits, sea fish and seabirds. So there's a lot to eat. ”

Zeng Lu said with a sweet smile: "Duan Gongzi, I like small animals the most, you can tell me about it carefully, anyway, everyone is so excited that they can't sleep now." ”

Duan Gongzi began to speak unhurriedly: "The most representative and symbolic animal of the Arctic is the polar bear. But now this ice and snow, most of the polar bears have now hibernated, can not see, it looks chubby, covered in a ball of white meat, it walks and swayed, swaying, a cute look, very cute, polar bears are the world's second largest bears, but also the second largest land carnivores, in the past people have always believed that polar bears are the largest land carnivores, until the discovery of 880 kilograms of Kodiak brown bears on Kodiak Island, polar bears were second. Male polar bears are about 2.4-2.6 meters long and generally weigh 400-600 kilograms and can even reach 800 kilograms. Female polar bears, on the other hand, are about half smaller than males, measuring about 1.9-2.1 meters long and weighing about 200-300 kilograms. By the time of winter sleep, they can weigh up to 500 kilograms due to the massive accumulation of fat, which is really a big one. And small and exquisite, ice and snow smart Arctic fox is also a kind of Arctic cute little animal, naturally also snow-white, snow balls, is also the best protective color, and ice and snow are integrated, very good to hide, Arctic fox body length 50-60 cm, tail length 20-25 cm, weight 2.5-4 kg. Smaller and obese. The mouth is short, the ears are short, and they are slightly rounded. The legs are short, and the whole body hair is white in winter, and only the tip of the nose is black. In summer, the body hair is grayish-black, and the ventral surface is lighter. It has very dense villi and few needle hairs, and the tail is long, the tail hairs are particularly fluffy, and the tail end is white. Arctic foxes can live on ice sheets at minus 50°C. The arctic fox has long hairs on the soles of its feet, so it can walk on ice without slipping. Group activities. “
