There were no quilts before the Song Dynasty, so how did the ancients keep out the cold?
Let's talk about the earliest period, for example, before the Xia Dynasty, people could build houses, but not many people could live in the city. At that time, people mostly used the fur of wild animals to keep out the cold. Now it is quite luxurious, and people at that time have dug holes in the ground as their own houses, which also have the function of wind and cold protection. I just don't know if anyone is poisoned by carbon monoxide because of burning wood to keep warm. People in higher classes have begun to use firewood for heating, and the wind-proof effect of houses and the cold-proof effect of wild animal fur are also quite good.
Secondly, in Xia and Shang dynasties, people began to build fixed cities, and large-scale farming operations began to appear, so that there would not be too much fur of wild animals. Although each family has a few pieces, they are not enough to wear, so people began to use hemp bags to fill all kinds of grass wadding, animal skin scraps and bark straws to make the first quilt and clothes to resist the cold in winter. At that time, people with status and wealth were all made of silk quilts, and then filled with soft hairs of various wild animals. According to the current statement, it was a duck down quilt, of course, it was not duck down at that time.
However, in later dynasties, this kind of fluffy quilt or clothes became popular, but the poor still could not afford to wear this kind of clothes. Most of them fill straw with sheepskin and linen to keep out the cold, and even make clothes with fish skin to keep out the cold. Most of them store firewood in winter and use it on very cold nights, while the kang appeared in the Han Dynasty, and the northern civilians began to be able to resist the cold weather. And those beggars, however, only have a light coat, and can only find straw or caves to live in and live day by day.
