"It's indeed your handwriting, yo, your little white face is very handsome. Meng Shan praised a few words, looked left and right and didn't see the clue, shook her head and said: "Forget it, with my IQ, it's better not to block you." However, I always felt that the number was sloppy, rushed, and seemed to be in a panic when you wrote it.

"Nonsense, that's why I can't figure it out. What exactly did I encounter and why did I use this number to remind myself? Also, why don't I have this memory at all! As he spoke, Li Nuoyi's brow furrowed again.

"The number seven is very ordinary, I don't understand what it means." Mengshan interjected: "Yiyi, I think you're thinking too much." ”

Li Nuoyi sighed secretly, thinking that if you have experienced my experience, you know that if you think more and think more, you may be able to save your life one day. She carefully put away the album and fidgeted as she walked around the living room.

"What are you doing?" Meng Shan was puzzled: "As for being so anxious? ”

"I was hesitant to call my man and ask about it." She hesitated.

Mengshan immediately came to the spirit: "This is a must. Just let me listen to his voice and scold him for you by the way! ”

"But he's been busy lately, and he's afraid to disturb ......," Li Nuoyi still hesitated.

"Yiyi, you're becoming less and less like yourself." Mengshan's gossip spirit was high, and she impatiently snatched the phone from her handbag and pasted it to the side of her face: "Fight! ”

Li Nuoyi glanced at her helplessly, and finally dialed the phone. With a few long 'Didi' sounds, the phone was connected, and the silent magnetic voice came: "Yiyi? Find me something! ”

"That's right, something strange has happened around me in the last few days." Li Nuoyi did not explicitly say that someone's photo was written by herself, but went around in circles to recount the cause and effect of the incident.

The night on the other end of the phone thought for a while, and said intermittently: "The number seven, well, is a bit interesting." ”

Meng Shan grimaced at Li Nuoyi: "Your man has a bit of a bad personality and likes to hang people's appetites." ”

Li Nuoyi smiled bitterly: "Regarding this issue, sometimes I want to beat him." ”

Ye Bu heard it obviously, he said in a loud voice: "Hey, don't talk badly in people's ears, I'm not deaf yet." ”

The two girls looked at each other and grimaced.

"Forget it, about 7, it has always been regarded as a mysterious number in numerology. Many people have heard of the Lucky Seven all the time, right? Also, the strangest thing is that as long as there are incredible phenomena in the world or in schools, they are called the seven incredible or unsolved mysteries for some reason. Of course, it is also possible that it is mathematically the largest prime number among the natural numbers with a single digit. ”

"Moreover, there was a great mathematician who once said that of all numbers, only seven is lonely. If you divide the numbers from one to ten into two sides and multiply all the numbers on each side, is it possible that the products of the two sides will be equal? ”

"This ...... I've been bad at science since I was in high school, how could I know. Mengshan subconsciously opened her ten fingers and gave up decisively after a few seconds.

"It shouldn't be equal." Li Nuoyi blinked: "Since there will definitely be seven on one side, there will only be one of them that is a multiple of seven, so it is absolutely impossible for the two sides to be the same." ”

"Uh, I don't understand." Mengshan was almost dizzy from the math conversation between these two people.

"Yes, expressing an integer as the product of prime numbers is called factorization. For example, 6 equals 2 times 3, or 8 equals 2 times 2 times 2 times 2 times 2. If the prime numbers on both sides are exactly equal, the factorization can be solved, but there is only one 7, so the equation cannot be established. Ye Bu explained quietly.

However, Mengshan, who doesn't emphasize the text and is not biased, and only wants to marry into a wealthy family, obviously still doesn't understand.

"Mathematical theories aside, in terms of time, there are seven days in the week, and the number 7 can also represent Sunday. If it is explained in Western divination, the direction and time represented by 7 is southwest, which means mystery and calamity. China has a similar claim. Nanayao, have you heard of it? ”

"Yes, I occasionally go to fortune telling, and I heard the numerologist mention it." Before Li Nuoyi opened her mouth, Mengshan had already answered happily.

"Qiyao is a general term for the sun, moon and five stars in ancient China. It refers to the sun, moon, gold, wood, water, and earth. These things are still on the lunar calendar and are said to be cultural knowledge left over from Taoist culture. Ye Bu ignored her and continued.

In the Tang Dynasty great poet Li Bai's "Great Hunting and Preface", it was written: The article is full of seven yaoxi, the production is related to the two instruments, and the teachers are all wonderful. In the Book of Jin, Volume 11, Zhi No. 1, it is: However, the three emperors Maide, the seven Yao are on the track, the sun and the moon have no eclipse of the change, and the stars are chaotic demons.

In foreign countries, "Qiyao" is also quite famous, and many regions use "Qiyao" to represent the seven days of the week. The moon god is in charge of Monday, so Monday is called "moon day"; Vulcan is in charge of Tuesday, known as "Fire Day"; The water god is in charge of Wednesday, which is called "Water Day"; The Wood God is in charge of Thursday, which is known as the "Wood Day"; Golden God is in charge of Friday, which is called "Golden Day"; The earth god is in charge of Saturday, which is called "Earth Day"; The sun god presides over Sunday, which is called "Sunrise Day".

The names of the seven days of the week first appeared in the ancient Babylonian civilization in the valley of the two rivers. Around 700 B.C., in ancient Babylon, a week divided into seven days appeared, and the four weeks were combined into one month. The ancient Babylonians built the Altar of the Seven Stars to worship the star gods. The altar of the seven stars is divided into seven layers, each layer has a star god, from top to bottom are the seven gods of the sun, moon, fire, water, wood, metal, and earth. The seven gods each have one day each week, so one god is sacrificed each day, and one god is named after each day. Therefore, the Western week starts on Sunday, which is different from the Chinese habit of starting on Monday. ”

"Cut, let's talk about it, I still haven't explained the strange thing that happened to your woman." Meng Shan complained.

Indeed, if you have to add meaning to a number, no matter how far-fetched, there are almost many bizarre explanations for each number. Therefore, this 'seven' will also have different meanings according to the changes in each person's senses. That's all I can think of now. And I know very well about Noi's recent schedule, so nothing special should have happened. "I can't figure it out when I don't say anything.
