What is China's lucky number?

Three, five, seven and nine are too many, so let's not talk about it.

The most typical example is that 25 jade seals were placed in the center of Jiaotai Hall. Take the meaning of "25th" in the Great Yan of Zhouyi for example.

Jiaotai Palace is one of the three remaining palaces in the Forbidden City. There are 25 precious seals used by Qing emperors, 23 of which are jade carvings. In the more than 500 years after the completion of the Forbidden City, there will always be repeated stories here. A mysterious man carrying a mysterious package asked to enter the palace to present a treasure. They all claimed to have found the imperial seal handed down from the Qin Dynasty. According to historical records, the famous natural Baoyu and its city wall in the Spring and Autumn Period were later carved into the national seal of Qin State. Qin Shihuang had hoped to bless his dynasty with this treasure. All subsequent dynasties longed to acquire and keep this imperial seal. The spread of the official seal of the state has run through the history of China 1500 years. It is said that when the Ming Dynasty destroyed the Yuan Dynasty, Mongolian tribes brought the official seal to Mobei. Since then, the real official seal has lost its trace, and various imitations have emerged one after another. This is a so-called imperial seal, which is kept in the Forbidden City. I don't know when and who it was given. According to expert analysis, it is actually made of clay. Emperor Qianlong did not agree with the legend of He Shibi. He is more concerned about the imperial seal of this dynasty. 1 1 years ago, Emperor Qianlong stored as many as 39 precious seals in the Jiaotai Hall, including fake national seals. Gan Long believes that even the real imperial seal of Qin Dynasty can't be put together with the precious imperial seal of Qing Dynasty. In the 13th year of Qianlong's reign, he proposed in the Preface to the Treasures of the Royal Jiaotai Hall that "since ancient times, there has not been a fixed number of treasure seals. Today, the treasure seals stored in the Jiaotai Hall are old, and the records are inaccurate and repetitive, so it is necessary to make textual research and arrange them in sequence, and the number of treasure seals is 25". This is the "five days in twenty" determined by Emperor Qianlong according to {Zhouyi Dayan}. He knew that since ancient times, no dynasty could not be destroyed. He set the number of precious seals at twenty-five, and borrowed {Zhouyi} to pray for God to bless the twenty-fifth generation of the Qing Dynasty, but in fact, the throne was passed to the sixth generation after Qianlong.
