Because it was very difficult for people to draw water in the past, it can be said that it takes a lot of manpower and material resources to drill a well. Your death is human and material resources, which can support drilling a well. However, due to the immature technology and lack of a good positioning system, an abandoned well is often drilled, which is equivalent to drilling a well for nothing. It is precisely because of this that the broad masses of working people know that it is not easy to dig wells, so even though every household now has running water, people still miss the scene of drinking water in the past, just as people don't forget to dig wells when drinking water to commemorate it.
Moreover, wells are also used as backup resources, because tap water has reached every household now, but sometimes it needs maintenance or new construction. It is inevitable that water will be cut off for a short time. People can't live without water, so when water is cut off, people can still carry and fetch water to ensure their daily life.
Another important reason is that tap water is generally pure water, which is filtered by rainfall layers. Filtering out viruses, bacteria and impurities into underground rivers also contains a lot of minerals, which is of great benefit to human body. However, some people are still used to drinking water wells, so they will put a water pump under the well and connect it to their homes through fruits, so that as long as electricity is turned on, the water pump in the well will work and continuously transport the water from the well to farmers' homes.
