Empress Dowager Cixi was buried in Yuling, Dongling, Qing Dynasty. She was buried with many treasures, including the world-famous night pearl. After Cixi died, the pearl of the night was in her mouth. In the 17th year of the Republic of China (AD 1928), the tomb was stolen by the army under the command of warlord Sun Dianying. According to Yu Shanpu's Sun Dianying, the building of Cide Mausoleum is luxurious, surpassing the tombs of all emperors in Qing Dynasty, especially the jewelry buried in coffins is more precious. After the death of Cixi on October 22nd in the thirty-fourth year of Guangxu (AD 1908), the eunuch Li attended the funeral and once recorded the buried treasures. He also said,' The bandits first robbed the big jewels around Cixi's body-jade watermelon, Chinese cabbage, Yu Lian, coral trees and so on. Then take away all the jewels under Cixi, then put Cixi's body on the coffin, grab the dragon robe, tear up the farmers' shoes and socks, and search all the jewels. Cixi's teeth were also pried open and the rare pearls in her mouth were taken away. The article quoted Sun Dianying as saying: "She (Cixi) has a luminous pearl in her mouth, which is divided into two parts. When it is closed, it is a ball, transparent and dull. When it was closed, it showed a green cold light, and her hair could be seen within a hundred steps at night. It is said that this treasure can keep the body from melting. It is no wonder that after Cixi's coffin was split open, Lafayette seemed to be asleep, only seeing the wind, his face turned black and his clothes were not suitable. I gave the night pearl to Mrs. Jiang () for me. " It's hard to know the pearl in the mouth of Empress Dowager Cixi, but I don't know what material it is. Some people think it is fluorite, but it is difficult to draw a conclusion without it. During the period of A.D. 1997, when I attended the "Cross-Strait Cultural Exchange" in Taipei, I asked a lot of questions about this luminous pearl. Because Song Meiling is old and lives in the United States, it is difficult to know its origin. I also asked Mr. Na Zhiliang, an archaeologist at the National Palace Museum in Taiwan (at the age of 92,/kloc-0 died in 1998). He shook his head and didn't know the details. Priceless treasure According to Jiang Buli's book The Case of the Theft of Cixi Mausoleum, the' 51Night Pearl weighs 422 yuan and 7 cents (now 133.4375 grams) and is worth12.82 million yuan. According to Jo Yeo-jeong's Antique Guide, "In short, if all the funerary objects of Cixi are recovered to pay off the foreign debts, it will be enough to enrich the country. The pricing and valuation of the listing were precious prices at that time, and all the values were the valuations of Chinese and foreign antique collectors and jewelers from then to Xuantongyuan, all of which increased tenfold. In the late Republic of China, it was appraised again, and it will be increased by a hundredfold. Today, it is no longer possible to attach importance to it. '
