Dirt can be found everywhere, something so common that even the aborigines of the reinforced concrete city have seen it. A clean house will feel dirty if it is sprinkled with a little dust. But do you know what it's all about?
First of all, we think of the fact that we can grow all kinds of food and vegetables, which provide us with the energy we need to survive, so we call the earth Mother Mother.
I'm afraid most people don't know what I'm going to say today. You've all been to the garage, right? In this prosperous era, even if the mechanic accidentally rubs the oil stain, there are all kinds of detergents to clean it. However, in the past, when laundry detergent was not even popular, cleaning oil stains was a headache. If a garment accidentally touches a little grease, then the grease is likely to stay with the garment for the rest of its life.
But at that time, the driver master (who usually drives will repair it by himself) would grab a handful of dirt on the side of the road after repairing the car, wet his hands first, and then rub them with soil, and so on several times, and he could wash his hands cleanly.
There's another one that I just found out recently. I have the habit of going to the small oil mill every year to extract oil, and the oil squeezed out of this way tastes delicious. Generally, there are peanuts and sunflower seeds, and I have also seen other people's rapeseed oil, perilla seed oil, sesame oil, and so on. Among them, those who have squeezed peanut oil know that in the last heating and disinfection process, the crude peanut oil that has just been squeezed will foam.
But this time I saw something different. The one who extracted the oil was a farmer brother, who planted peanuts on two acres of land at home, and there were more than 1,000 catties of peanuts in the shell. Maybe there are a lot of them, but they are not very clean, and there is still a little dirt on the outside of the peanut shell that has not been cleaned up. Not a lot, does not affect oil extraction. However, in the process of heating and disinfection, everyone present was surprised. His oil didn't foam, and it didn't spill out when it was boiled like boiling water. You say God is not magical?
Finally, I would like to say that our knowledge of the world is still very limited, and perhaps one day, we will find more useful things in the soil.
