The word "yin and yang well" may sound scary, but the fact is that there are two wells at close range, one is sweet and the other is turbid. It is not supernatural, but a natural phenomenon caused by geographical environment and geological reasons.

Many people feel cold at the sight of the word yin and yang. Actually, I used to be like this. See or hear these two words, I will feel inexplicable fear. At that time, I saw a report on the internet that it was possible to lose weight quickly by using yin and yang water. There are two different versions of the so-called yin and yang water: one is that the boiled water is mixed with the cold water overnight and drunk, and the other is that the boiled warm water is mixed with the raw water flowing directly from the faucet. I tried at that time, but I didn't insist. It is also reported on the internet that a person has been drinking yin and yang water for a long time to harm people.

Yin-yang well is just a natural phenomenon, which has nothing to do with paranormal.
