As we all know, the ever-burning lamp has been a magical existence for thousands of years. In some records, the ever-burning lamps were installed in the tomb of Qin Shihuang, because China people have been there since ancient times, and they are also called yin houses in the tomb after death, so they will be taken seriously. After their death, they want to live like the former palace, so there is an ever-burning lamp, and it is also reasonable for them that the ever-burning lamp in the tomb can burn for thousands of years
Second,? custom
Not only in China, but also in ancient Egypt, Greece and Rome. After people die, it is customary to put a lamp in front of the grave to show their identity, which will be more extravagant. Put on an unlit lamp to show that you will always take care of the dead. Amazingly, when a grave robber goes to rob a tomb, he thinks it should be opaque, but he is horrified to find that on the roofs of some ancient tombs, a bright lamp casts a long light into it.
Third,? Special substance
Scientists have found that books about the ever-burning lamps in ancient tombs in various countries have taken more than 30 years and hundreds of experiments, and finally they have been made into ever-burning lamps. The principle is that Huang Lin is combined with other flammable substances, and this special substance is constantly volatilized in the air. The ever-burning lamp in the ancient tomb is this substance. When the wooden door is closed, the air in the tomb will slowly run out, and even the ever-burning lamp will go out. After these substances, this phenomenon will not occur.
Hundreds or thousands of years later, someone enters the wooden door, which will bring fresh air, so it will attract the ever-burning lamps that are going out, which is why the ever-burning lamps that have entered the ancient tomb room for thousands of years will still light up.
In fact, some old sayings are not superstitious, but have certain scientific truth, so we can understand what is going on, which we think is not particularly dangerous but normal.
