The yurt consists of three main parts: wood, felt and rope. As a nomadic people's residence, the production of simple, easy to load and unload the residence is the first choice, and the yurt is the nomadic people to adapt to the nomadic life and the creation of this residence, easy to dismantle and install, easy to nomadic. Because: first of all, in the case of the same material, the circle has the largest area. Geometry tells us that the area of a circle is larger than that of any other shape with the same perimeter, so if the same amount of material is used to make something with the largest volume, a circle is of course the most suitable. Secondly, cylindrical shape has the greatest support and centripetal force. In addition to the smoothness and continuity of the wheel, the centripetal traction of the wheel ensures the stability of its rotation. In addition, it can prevent external damage. As we know, if a plant's stem is square, flat or has other angles, it is more vulnerable to external impacts. Unlike a round one, when the wind blows, no matter which direction the dust and debris come from, it is easy to pass along the tangent direction of the round surface, and only a small part of the plant is affected. This is because the area of a circle is larger than that of any other figure with the same diameter (side length).

Thus, the yurt has a larger footprint and more space inside; the area where the roots can absorb water and nutrients is larger; and the stem transports more water and nutrients
