In 2008, a large tomb from the Ming Dynasty was discovered near Banqiao Sanshan in the southern suburbs of Nanjing. On the inner wall of the epitaph cover, which was covered with exquisite cloud patterns, eight large characters engraved in round seal characters were clearly visible: "The Princess of Baoqing was born." However, it had been seriously damaged. During the process of rescuing the tombstone, archaeologists accidentally suffered water and soil erosion. The next day, under clear skies, archaeologists saw an exquisite dice inlaid with red beans, dragons and phoenixes carved in eight directions in front of the tombstone. Upon closer inspection, the red bean was not a real red bean, but a rare ruby as big as a pea, with the word "Qingyang" engraved on it. Searching for evidence revealed that there was only one royal family named Qingyang during the same period. Princess Qingyang, the princess of Mengcheng, married Huang Chen. There are no other records, but unofficial historians say that he has the most beautiful appearance in the world, is astonishing to the heavens, has eyes like peach blossoms, a charming smile, is good at music all his life, and is deeply favored by Taizu. Who rode through the Ming Palace City 600 years ago, and saw a canary trapped in the vermilion palace wall, sighing that he was born in an imperial family. Who is holding the pipa and walking slowly on the snow to the Zhonghe Hall, singing the melodious sound of "Fifty strings of brocade for no reason, one string and one column thinking about the Chinese years". Who is it that wears splendid clothes and holds the hand of the emperor to step onto the pinnacle of power and look down upon the world? The story of this exquisite dice begins 600 years ago.
