Hu Jiaojiao looked at Xiao Fei with a scorching gaze, and said enviously: "Brother Xiao Fei, you are really amazing, you know everything, you actually know that it is a wonderful idea to use local materials in the snow and build a house with ice and snow." Xiao Fei said disapprerovingly: "Actually, it's not that I'm good, it's those Eskimos who live in this icy and snowy land, and the uninhabited Eskimo people are amazing, these whimsical, unbelievable, and unexpected houses are invented by them, and their houses use the principle of warm air to maintain room temperature and survive the cold winter." The Eskimos refer to all houses as Igloo. However, not all the Eskimos we imagine live in snow houses, in fact, three-quarters of the Eskimos have never seen such snow rooms, and only the polar Eskimos on our side live in the snow rooms all year round. Since there was no timber or mud, they had to build their houses with snow from local materials. This arctic region is so cold that the winds and temperatures are so low that tents can't keep them out, so the Eskimos in the region built the famous igloos. Kupp Eskimos, Nets Slick Eskimos, Igrunik Eskimos, Reindeer Eskimos and Quebec Eskimos generally use igloos in winter, although these people make up only 8% of the total Eskimo population. The construction of a igloo requires a certain amount of technology, mechanical stability, and strict shape requirements. I think it's a masterpiece of architecture. And this is a must-learn skill required by our company, and every employee in our company has been trained, so I learned it with my heart, and finally came in handy today. So it's just a piece of cake for me. "We just did it, and we all worked together to find the ubiquitous building material - ice and snow, and Xiao Fei told us that these snow blocks are not casual, but particular, and we need to choose snow blocks with uniform texture and suitable hardness.

We searched for a long time, first using tools to test whether there was ice and air in the snow, and the most suitable thing was to choose the snow that was blown by the wind.

The size of the snow cube is determined according to the size of our snow house, the larger the house, the larger the snow block will be cut, our snow house is not big or small, so we cut it more moderately, we easily use a sharp sword to split them into a patchwork of rectangular large ice blocks, after a while, the snow will be neat, orderly lightning strikes up a large number of square snow bricks, completely enough.

Under the guidance of Xiao Fei, we first estimated the size of the starting circle and used three connected snow blocks to build a slope as the beginning of the spiral snow wall.

Each snow brick is a cube, but the inner side has a certain arc, forming an arc, and each snow brick must be accurately matched to make the snow room strong and not collapse.

We built a wall made of snow blocks, and when we built the second or third layer of bricks, we had to open a temporary entrance and exit on one side.

However, these snow bricks are not enough, we have to stagger out of the inside, and then carefully transport the bricks in, for fear of damaging the built part, after a certain height, we also have to persevere in building to four or five circles, increasing the inclination inward, and Xiaofei particularly emphasizes that the most critical technology is how to put the snow into a circle, spiraling, so when we build to the top, we must increase the inclination of the rise, which requires us to be accurate, cut down the bevel of a brick accurately, so as to connect the next brick seamlessly。

The two bricks had to be cut very well and fit each other, and we finally stacked the layers of dense ice cubes into a steamed bun-shaped hut, and finally poured water between the ice cubes, and these ice cubes froze into one, tightly fitting and impermeable.

It is definitely a pollution-free building material, a pollution-free building, we are busy, busy for a long time, and finally it is done, only the last cap remains, and we carefully cut out the last brick according to the size of the top hole.

Since the top hole is often irregularly shaped, we have to use both hands to hold the snow brick from the inside to the outside, and cut the shape of the top hole until it fits perfectly, and seal the top hole.

By this time we were all completely sealed inside the igloo, and there was no way out, and we had to dig out another exit to the igloo to finally be done, and we would build the temporary access holes, fill the gaps between the snow blocks, and then dig a door at the bottom.

And a vent should be opened in the roof to prevent the snow bricks from melting due to overheating in the house. Xiao Fei reminded us that we also need to dig a snow passage outside the entrance to be all right, because this passage can maintain room temperature - wind and cold air cannot directly enter the house, and warm air gathers upwards in the house.

When we had built the igloo, we found that we didn't have beds, stools, tables, and other necessities, so we began to be in high spirits, and we began to build our furniture with the snow and ice that were commonplace in the North Pole, and we piled the snow into the sleeping place, and covered it with animal skins and so on.

Finally, this little snow house was built with the concerted efforts of everyone, and it was completed, although our snow house is small, but it has everything available, which is really pleasing to the eye and happy.

However, Xiao Fei regretted that because of the lack of time, he could only simply make a small house, and if he had enough time, he would definitely build it beautifully, like a magnificent palace.

But after going in, it is indeed quite comfortable, tightly fitted, just like the Mongolian people's yurt, the round roof, it looks really pleasing to the eye, unique, we are in the fire, boiling water, for a time steaming, the clouds are steaming, I feel that there are at least ten or twenty degrees in the house, ambiguous and extreme, a warm feeling like spring, and the ice and snow world of dozens of degrees below zero outside the snow house is in sharp contrast, we happily lie on the built ice bed, I feel that the ice bed is also warm, not at all like the ice bed cultivated by the little dragon girl in Mr. Jin Yong, and this steaming snow house because of the isolation of the outside air, There is no ice and snow, the feeling of incomparably cold, but it gives people a feeling of spring, spring and the world, we are happy to eat the canned beef that we carry with us after a little news, while drinking the Greek grape wine that we carry with us, talking and laughing, it is really a joyful and joyful feeling.
