Why Can Blankets Keep Warm

Fashion is a kind of reincarnation. In fact, items that look very fashionable and modern have become fashionable hundreds of years ago. Wu Yuan: Blankets, woolen mats, woven with colorful flowers, Shennong's mats, and Yao's famous carpets are the very common blankets today. The appearance of blankets is the product of China's special climate.
At first, it was used to keep warm, but with the development of society and the progress of the times, the existence and function of blankets have gradually changed. In the eyes of the ancients, blankets began to become decorations and status symbols, and even the production process of blankets began to become complicated, the process became more complex, and became a fashion item of the ancients.
At the beginning, the production of blankets was very simple. It was simply the care and weaving of animal fur. In particular, the nomads on the northern grassland had higher requirements for warmth in their perennial grazing and migration life. In addition, a large number of cattle and sheep provided sufficient fur, so fur products were very common among nomads.
Compared with the Central Plains, there is a shortage of furs. In addition to some top nobles who can obtain expensive furs, most bottom people can rely on straw mats and other things to keep warm. Relatively speaking, hay is easy to obtain, cheap and easy to process, which is very suitable for the needs of bottom people.
At the beginning, the purpose of blankets was to keep warm, so they were not exquisite at all. They could be said to be rough and simple, especially straw mats, because they were cheap and easy to obtain. Most people would discard them after using them once.
For people in the pre-qin and even the qin and han dynasties, blankets were very common common articles, which had something to do with the living habits of the ancients. We can clearly see that there were very significant tables and chairs in the murals in the wei, jin, tang and song dynasties. For example, in the famous "Han Xizai's Night Banquet", people were sitting on the hutch.
