There is indeed a bead in Galeries Lafayette's mouth, which is actually a night pearl, and it can be divided into two pieces, which together form a sphere with a green cold light, and you can see your hair within a hundred steps at night.

Of course, Galeries Lafayette took a fancy to this bead, not because he could see people. But with this thing, you can keep your body intact. It is said that when the soldiers split the coffin, Lafayette was still like a sleeping living person. It was not until he saw the wind that his face slowly began to turn black.

This is the role of the night pearl.

So, what is the night pearl? It is actually a diamond.

In history, there was a "Mughal Diamond" named by Shah Jahan, King of Mughal Dynasty in India, which was once thought to have been lost for nearly 350 years. For many years, people have been wondering whether the "Mountain of Light" diamond on Queen Elizabeth's crown in Britain, the "Sea of Light" diamond set in King Pahlavi's crown in Iran, or the "Mountain of the Moon" diamond collected by the Russian czar's royal family, whose whereabouts are unknown now, all come from this "Mughal Diamond" original stone.

At present, however, there is a view that Afghanistan once made an expedition to India and obtained this diamond from India, and then presented it as a tribute to Emperor Qianlong of the Qing Dynasty. The Great Qing Dynasty has been handed down and finally fell into the mouth of Cixi.

So, what happened next?

First of all, it fell into the hands of grave robber Sun Dianying.

Of course, Sun Dianying wanted to get rid of the notoriety of grave robbery, so he gave this pearl to Dai Li and asked him to give it to Chiang Kai-shek's wife, Song Meiling.

So some people say that it is for this reason that Chiang Kai-shek finally spared Sun Dianying.

Later, Song Meiling took this pearl to live in the United States.

Finally, there are two kinds of speculations. First, it is said that Song Meiling spent all his cash soon after he arrived in the United States, so what should he do? She gave this luminous pearl to the family of Rockefeller, the founder of Mobil Oil Company (Standard Oil), and it is still in the museum in Los Angeles, but no one has seen it, or no one has come out to confirm it.

Another way of saying it is that Song Meiling imitated Cixi before she died and stuffed the night pearl into her mouth. Of course, there is no way to prove this statement.

So, don't worry about this bead, haha!
