I saw this phenomenon when I traveled to Shanxi. At that time, I didn't know that I had put some small change in it, thinking that I could be blessed and lucky. Later, I learned that this was not the case. There is a saying in Shaanxi that fat water does not flow out of outsiders. In the past, rural water use was not like this. Tap water is installed in every family. Everyone used to eat well water. In some places, water resources are scarce, and the water in the water tank is used for washing clothes and watering the land.
So there is a big water tank at home, which is often filled with water. When I was a child, there was a big pool at home. Every time it rains, the water in the pool is full, so my family washes clothes and vegetables with rain.
Of course, if you go to those big houses, the water in the water tank has another purpose, that is, fire prevention, because the previous houses were basically made of wood, and the biggest hidden danger of this kind of house is that it is prone to fire, and the water tank is often filled with water, also for fire extinguishing.
I think this is the meaning of rich water tank, so knowing this, it is not difficult to understand the sentence of poor firewood and rice.
It's not that poor firewood can't accumulate firewood here. In the past, farmers used to make a fire to cook, and firewood was an indispensable material for making a fire, so rich firewood was also very important for farmers. However, none of these firewood can be stored in the kitchen at home, because the consequences of a fire are unimaginable, so firewood must be stored far away from home and not too much. My kitchen is because there is a lot of firewood in it, but it is difficult to put out the fire. Fortunately, the kitchen.
This seemingly simple truth, summed up by farmers in concise words, may be the ordinary and great wisdom of farmers.
