People in this era are in good health, because they have been doing farm work, and their bodies have been fully exercised, and they are not as afraid of the cold as people now. Moreover, people have been living in cold places, and their bodies will have the corresponding ability to keep out the cold, and they will not be frostbitten in winter. And people's warm-keeping measures are better. They will wear deerskin hats, shoes and sheepskin jackets to wear on themselves. In this way, it can play an excellent warm-keeping effect, and when you go out, wear a big hat, and the whole person is wrapped in clothes, which will not be blown by the cold wind at all. Indoor thermal insulation measures are better, thick walls will be made, and the temperature of the kang will reach 20 or 30 degrees by burning it.
Farmers in Northeast China will not go out to work in winter, but will reserve food before winter, such as meat or cabbage. They will put these cabbages in the cellar, and the temperature in the cellar will be higher, so that the cabbages will not freeze. There will also be many coarse grains, such as potatoes or sweet potatoes. You can open the cellar when you want to eat them. Moreover, the meat can be placed directly outside, which will be frozen hard and can be moved when eating. Therefore, people in Northeast China will not pickle bacon. Outside the house is a natural refrigerator, which can play a very good role in keeping fresh. There is no need to use meat to keep the meat fresh. Northeasters will spend the winter in their houses, so that they can be more comfortable and won't get hurt.
Now the northeast is also heated, and the home is warmer. Winter is also very comfortable, so it's not so hard.
