As early as ancient times, buried alive was popular. According to the research of historians, this custom of burying the living began in Shang Dynasty, so it was popular in ancient times for a long time. During this period, there was no requirement for people to be buried with the living, but later, people preferred to be buried with boys and girls.
At that time, everyone wanted to be immortal, and people didn't know where they heard that boys and girls were more immortal than others, because they were young and didn't understand the world. Therefore, in order to satisfy their desires, people selfishly choose to be buried with boys and girls.
What's more, boys and girls have to be buried with them, and the owner of this tomb is immortal after his death. Mercury in children. At that time, these children were naive and ignorant, but they didn't have time to enjoy this beautiful world, because the tomb owner was leaving this world because of his own selfish desires. This is undoubtedly very unfair to them. The tomb owners forced the boys and girls to drink a lot of mercury when they were alive. Unfortunately, these children died not long after touching the water.
When these boys and girls are buried with the tomb owner, it is not known whether the tomb owner will become immortal. But there was no human rights in that feudal society at that time, and only powerful power could make them live better, which was one of the reasons why the power struggle in ancient times was so fierce.
