How did the ancients keep out the cold when it snowed heavily?

We should admire the wisdom of the ancients, who used many methods to keep out the cold:

1, cotton-padded jacket, of course. "A slip of the moon hangs on the capital, and ten thousand hammers are knocked." At that time, cotton-padded clothes were made, but there was no cotton. The method of making cotton-padded clothes is to mash all kinds of fabrics to make fillers;

2. Clothes made of various animal furs. Now we advocate ecological protection, protect animals, and don't use animal fur to make clothes. The ancient ecological environment was very good, and the fur of various animals was a very good raw material for making clothes. In a Dream of Red Mansions, Sister Lin wears deer boots, eats venison and drinks on snowy days. And brightly colored coats are also great. There is also a duck feather coat made by a Russian tailor. These are warm and beautiful, against the snow, really beautiful.

3, all kinds of food. All kinds of warm food. Hot and warm wine, wine like honey. There are crabs and all kinds of barbecues. It not only relieves thirst, but also keeps out the cold. Really kill two birds with one stone;

4. charcoal fire for heating. In ancient times, the technology of burning charcoal was very advanced. There is a kind of silver carbon, which has no smoke when it is ignited, and heating is very useful.
