If it's cereal, it's very dry, and then every family lives in a loft upstairs with a big cabinet on it. Put the dried millet in the cupboard, and then take it out and peel it in a place with a water mill when you want to eat it. Beans are dried and stored in sealed bags or baskets. Potatoes and pumpkins are in the attic, and sweet potatoes are in the cellar.

However, sorghum is different. Each district has a grain depot, which is used to store sorghum every year, that is, sorghum for brewing Moutai. Today, it is still the same, that is, ordinary people dry sorghum until it is chewed in their mouths, and then the warehouse receives it at the contract price to ensure that the sorghum will not be moldy and rotten, and then it is handed over to Maotai Distillery to brew Moutai in September.

The dry soil in the north of the warehouse or cellar is thick, so many people dig cellars at home to store food. The water level in the south is high and the climate is hot and humid, so it is not feasible to dig the cellar. Therefore, the warehouse can only be set on the ground, and some are in the form of diaojiao building, which is convenient to isolate moisture.

Sealing fruits or other foods in clay pots and sealing them with mud or water can isolate the air well. Sichuan sauerkraut is made in this way and has a unique flavor.

The most typical use case of drying method is drying bacon. During the Spring Festival, I bought a lot of pork and dried it for a few days. People in the mountains also smoked with fireworks, so the bacon tasted like firewood.

The country is people-oriented, and the people take food as the sky! All dynasties have attached great importance to food, because people are like iron, rice is like steel, and there is no food and hunger for a meal. People can only have secular desires if they have enough to eat and drink, so they can not panic if they have food at home! As for the earlier ancients, we don't know how they were stored, but the wisdom of the ancients makes us admire today, because the scientific and technological information was underdeveloped at that time, but many inventions in life were very remarkable. Many inventions are still in use today.
