According to people's ideas now, it should be very unclean, but at that time, everyone didn't take it seriously. Some places are still eating well water, and frogs and toads are still the same. So the toad in the well is nothing to ordinary people. It seems very unsanitary now, but it is a real truth. I was lucky enough to spend ten years in the spring and autumn in the countryside and had a profound experience of rural life. A word evoked memories of life at that time. In rural life at that time, there were toads in the well, maggots in the sauce and sand in the rice, which was the most common and common phenomenon.
Well water is a well that villagers spontaneously dig in the middle of the village in order to eat clean water. The well is about ten meters deep and about one meter in diameter. There are always stones around, and frogs will go in after a long time. At present, frogs may be dirty and well water can't be eaten. In rural areas, soy sauce at home is made of soybeans. After fermenting for a period of time, put it outdoors. Sometimes when it's raining, maggots grow when you go in. This phenomenon also exists in rural areas. This is not surprising.
Frog in the well, this is perfectly normal. People can't live without water, and well water greatly facilitates the people. On rainy days, when toads, frogs, snakes and mosquitoes are active, it is common to jump into wells. Living toads are not taboo, but it is not surprising that there are dead toads in the well. This rural proverb describes some common phenomena in rural areas. Literally, there are toads in the crystal and maggots occasionally in the meat sauce. These are not fussy things, just like eating a grain of sand once in a while. These are all very common things.
