1. Why are there 9999 half rooms in the Forbidden City? The Forbidden City in Beijing is the largest imperial palace in the world. The Forbidden City covers an area of 720,000 square meters, forming a square. The main entrance facing south is the meridian gate, the north gate is the meridian gate, and the east and west sides are called Donghuamen and Xihuamen respectively. How many rooms are there in this ancient building complex? There are 9,999 half rooms in the Forbidden City, which is odd. Why build a "half room" if it is less than 10000? It is said that there are 10000 palaces of the Jade Emperor in the sky, and the human emperor is the son of the Jade Emperor, so his specifications are lower than that of the Jade Emperor. The so-called "half room" refers to the small room downstairs in Yuan Wen. In fact, the reason why this hut is made so small is for the sake of beautiful layout. It should have been a room. PS: It's just a legend. According to the actual measurement, the Forbidden City has 8707 rooms. 2. Why is the son-in-law also called "East Bed"? Dong Chuang is another name for son-in-law, from Wang Xizhi, a calligrapher in the Eastern Jin Dynasty. Wang Xizhi is the nephew of Prime Minister Wang Dao. One day, a teacher sent someone to Wang Fu to choose a son of the Wangs as his son-in-law. Your young sons heard that a teacher's daughter was young and beautiful, and everyone wanted to be selected, so they changed clothes and received visitors. Only Wang Xizhi didn't care, still lying in bed. When the newcomer returned to the mansion, he told the teacher, "The idlers in the Wangs are all good. I was a little stiff when I heard about choosing a husband. Only one childe is still lying naked on the bed in the east wing, as if he didn't know about it. Unexpectedly, the teacher nodded and said, "This is the son-in-law I want to choose." From then on, people called the son-in-law "the East Bed". Ps: The origin of Nu Wa The story of Nu Wa comes from the history of the Eastern Zhou Dynasty. According to legend, there was a daughter named, who was brilliant since she was a child. When she grew up, her appearance was peerless, especially blowing sheng, whose voice resembled hers. When Nong Yu 15 years old, Qin Mugong began to consider finding a husband for her. Nong Yu said: You must know someone in blowing sheng to sing with me, or you won't get married. Then one day, Nong Yu had a dream in which a fairy who claimed to be the Lord of Huashan sang with her. Nong Yu told Qin Mugong immediately after waking up, and Qin Mugong sent someone to Huashan to find him. Sure enough, he found a strange man named Shaw History, with a crowned crane, a jade appearance and red lips. He is proud and extraordinary. After the messenger brought him back, Mu Gong ordered him to play Xiao. At that time, the birds were singing together, and Mu Gong was overjoyed, so he betrothed Nong Yu to Shaw History. The next day, a breeze blew under the moon, and a phoenix came from a dragonfly in the sky. So, Shaw History crossed the dragon, and Nong Yu rode the phoenix and left in Xiangyun. Leave a story about son-in-law 3. According to historical records, in the early Ming Dynasty, four major cases caused a sensation, including a major corruption case-"Guo Huan case". Guo Huan served as Assistant Minister of Finance. During his tenure, he used his power to collude with local officials and embezzle money and food. Corruption accumulated to 24 million stone refined grain. This figure is almost related to the total amount of autumn grain collected in the country at that time. The case involved 12 senior officials in China, officials from six ministries, and many local officials and landlords. Zhu Yuanzhang was shocked by this. He ordered Guo Huan and other conspirators to be beheaded, enacted severe laws to punish economic crimes, and implemented some effective measures in national accounting management. One of the most important items is to change the Chinese character "one two three four five six seven eight nine 100,000" to "one, two, three, four, five, six, seven, eight and nine miles". The implementation of this method has blocked some loopholes in accounting management. Since then, in the process of accounting with "capital", people have gradually replaced "boundless" with "hundreds of thousands". Later, with the number of * * * introduced into China, it matched with the capital number of Chinese characters, forming a complete accounting number system, which has been in use ever since. Ps: Capitalized numbers have been used since the Ming Dynasty and are still in use today. 4. The origin of honorific titles for parents-in-law. Ancient emperors often came to the top of famous mountains, set up altars to worship the mountains and rivers of heaven and earth, and made princes and ministers of Jin Dynasty, which was known as fierce in history. Li Longji, Emperor Xuanzong of the Tang Dynasty, went to Mount Tai to "seal the temple". In the book, Zhang said that he would be a "temple-closing messenger". Zheng Yi, his son-in-law, was promoted from grade nine to grade five. When Emperor Xuanzong of the Tang Dynasty asked about Zheng Yi's relocation, Zheng Yi faltered and was speechless. Huang Zanzhuo, who stood by, sneered: "This is the power of Mount Tai." Emperor Xuanzong of the Tang Dynasty was very unhappy and immediately let Zheng Yi return to his post. Later, when people learned about it, they called their wives and fathers "Mount Tai". Because Mount Tai is the head of the Five Mountains, it was renamed "Grandfather". The name "mother-in-law" followed. PS: Call your parents-in-law, and know how it came. 5. The origin of the engagement ring The first person in the world who used the ring as an engagement token was King Maximini of Austria. 1477, Maximini met a princess named Mary in a public place. Her beautiful appearance and elegant manners fascinated Maximini. Although Maximini knew that Mary was engaged to the French Crown Prince at that time, in order to win her love, Maximini decided to take a chance. He made a precious diamond ring specially for Mary. In the face of this finely crafted and glittering diamond ring and Maximini's true feelings, they happily combined. Since then, the diamond ring has been used as an engagement token. This has become a tradition.
