Why did people stock up on food in the past?

Because in the past, if you didn’t stock up on food, you would starve to death, that is, starve to death in a literal sense. Then the police and forensic doctors came to watch and gave the result: "There is no vicious criminal case, this family starved to death."

Since the late 1980s, the monthly income has been no longer in the tens of yuan, there have been more greenhouses, winter vegetables have become cheaper, and there are fewer vegetables to store. My family's weight slowly dropped from 3,000 jins to 2,500 jins, then 1,500 jins, and then 3,500 jins. My vegetable cellar has also been shrinking in size since it was able to accommodate a dozen children. In the end, we dug a shallow pit half a meter deep. When I bought a building two thousand years ago, I could no longer dig a cellar to store vegetables. But in winter, I still like to buy a cart of vegetables and put them on the north balcony. Generally, the balcony on the north side will be colder (even if it is closed), it is probably only a few degrees above zero, about the same as a refrigerator.

I didn’t talk about sauerkraut. My family also pickles sauerkraut. I started dealing with the Chinese cabbage after I moved it into my house. I have a piece of granite at home that is used for pressure cylinders weighing more than ten kilograms. It has been used for more than ten or twenty years. I was mainly talking about why I was stocking up on vegetables, so I didn’t talk about sauerkraut. Suddenly I thought about it, it’s really a weird thing to get sauerkraut in winter. "Enjoy", it's a big tank near zero, with some ice particles floating on the water, and then I fish out two sauerkraut plants from it!
