Because it is adjacent to Mochou Road, this old house is noisy and not suitable for teaching and office, so the first middle school rented out the ground floor. There are many students, there are many residents around, and the business on the first floor is good, with all kinds of snacks, stationery and other shops.

On the second and third floors, there were single young teachers living in the first middle school, and the conditions of the first middle school were good, and the developer built an education community on an old plot of land across the road from the school, and the newly built community had more than 100 houses, which were still renovated and given to the leadership of the school and the education committee. The leaders are very happy with such a good benefit, and the faculty and staff are also happy to move in, which was a few months ago.

"The teachers in this school are really good," the interns who came together and were about to graduate were very envious. It is said that there are still more than a dozen empty houses waiting for new teachers.

Naturally, the people who can be assigned to this school for internships are all outstanding students from various departments, and there are one or two senior brothers and sisters who stay here every year. The female teacher surnamed Lin who received her just now was introduced as the senior sister of the previous three sessions, from the Department of Sociology, and now she is the administrative secretary to the principal.

A week later, President An, the head of the first school, cordially met with this group of interns and asked them about the cold and warmth.

As the only high-achieving mathematics student, Song Yang was invited by Principal An to be his daughter's tutor after the meeting, and the principal said that his daughter was in the third year of junior high school this year, and she was in No. 1 Middle School. The eyes of the others looking at Song Yang were different!

The building near the water is the first to get the month!

Without spatial distance, time seems to pass very quickly. Although there are still not many words, Song Yang and Ma Xiaoman are already deeply familiar, and with a glance, they seem to know what the other party is going to say.

On the road in early winter, people who get off work are crowded with bicycle lanes, only to see crowds of people, and pedestrians on the sidewalks are hurrying. The cold wind was blowing, and the bare trees, like bald old men, could not withstand the attack of the northwest wind, swaying in the cold wind.

The millennium bells of 2000 have passed. Last night, Song Yang accompanied her in the Bell Tower Square to excitedly count down "ten, nine, eight, seven...... One, zero". After being excited, I wanted to learn from the surrounding crowd to hug each other, but seeing the melancholy that suddenly appeared on her red face, the words she wanted to say were stuck in her throat like fish bones.

"Go back, it's not too early......" she said, and she didn't say a word on the way back. Song Yang knew that she was worried about her work, and if there was no good unit in Jinling to accept her, she would have to go back to her hometown.

Just like on campus, Song Yang walked slowly behind her, thinking in his heart that this moment, he had also interned in Zhonglou No. 1 Middle School for two and a half months, and seeing that there was less than half a month to go, the internship period was about to end.

"Don't take it again...... Just, there's no chance! Song Yang said to himself in his heart.

"Bang, pound", knocked lightly on the door of the opposite room, and opened. It was warmer in the house than in the north room, and she wore very little.

A heater was next to the desk, glowing red.

Seeing the doubts in Song Yang's eyes, she said, "Teacher Lin gave me the ...... today Isn't it much warmer, she's so nice......"

"I said why is it so comfortable, I'm in your room tonight......" Song Yang rarely looked like a scoundrel.

Jin Xiaopang often said that he can't be too honest, he is honestly bullied, and no one wants to be honest...... The newspapers also said that "men are not bad, women are not loved...... and I should learn something.

"Go......," she flew over with a smirk.

"It seems that she is in a good mood today......" Song Yang said in his heart.

"What is this?" Song Yang picked up a cyan round jade hanging on the desk, tied with a thin red silk rope on it, and the front of the jade hanging read: "All things are not the master, but the true ruler, Muhammad, is his messenger", and the other side of the jade hanging is a grid, there seem to be dots and numbers in it.

Jade, still hot.

"Magic Square, this is the talisman of our Islam...... My mom gave it to me when I was in college, hoping to bless me with peace for the rest of my life......"

"It's also called a magic square?" Song Yang, a mathematical genius, looked puzzled.

"Yes, we Islamists usually have a magic square......"

This is the first time Song Yang has heard of this.

He likes mathematics, and naturally knows the origin of the magic square: China has the theory of "Hetu" and "Luoshu". Legend has it that in ancient times, the Fuxi clan took the world, governed the country in an orderly manner, moved Shanghua so a dragon horse jumped out of the Yellow River, carrying a picture on his back, but as a gift to him, this is the "river map", this is the earliest magic square. Fu Xi deduced the gossip with the "river map".

When Xia Yu ruled the flood, a big turtle surfaced in Luoshui, and there were pictures and words on its back, which people called "Luoshu". There are a total of 45 black and white circles in the "Luo Shu" painting. Represent these small circles and numbers that are joined together to get nine numbers.

Confucius recorded in his work on the Book of Changes, "The Upload of Words": "The river produces a map, Luo produces a book, and the sage does it." ”

In the thirteenth century, Yang Hui, a mathematician in the Southern Song Dynasty of China, first carried out a systematic study of the magic square, calling these nine numbers "vertical and horizontal graphs".

Later, the famous European mathematicians Fermat and Euler both conducted research on magic squares.

Even, some people think that "Vena" is a relic or signal of aliens; The patterns on Vena and Hetu describe the genetic ordering rules of cosmic creatures (including aliens), and the magic square above is the self-introduction of aliens to earthlings.

Nowadays, the Magic Quadrant is still one of the research topics of combinatorics, and through the joint efforts of generations of mathematicians and mathematics enthusiasts, the various magical scientific properties contained in the Magic Square and its variants are gradually being revealed.

"Yes, in the fifteenth century, the Magic Square was introduced to Europe by our Islamists, who, like us, believed that the Magic Square could suppress demons and prevent evil, and used it as a talisman and also called it 'Square'......" Ma Xiaoman said in a low voice.

“Magic-Square？ So that's it...... This jade is really good, it's not cold at all...... Song Yang took it to his nose again and sniffed it, "Well, it's quite fragrant......"

Before she finished speaking, she was snatched back by Ma Xiaoman, her cheeks instantly became hot, and a touch of shyness spread in her heart.

"Ah," Song Yang instantly understood, this smell was nothing else, it was the body fragrance on her body......

I couldn't help but panic for a while, in front of others, I took other people's personal belongings and sniffed indiscriminately, which made other girls how to deal with themselves. It's me, my face is also hot, I think I'm ugly, hurry up.

Before the door closed, Song Yang hesitated and said: "I, go back to sleep, tomorrow night, can I invite you to watch a movie tomorrow night, there are some words, I want to say to you......"

"Hmm...... Ah, no, I'm looking for something with Mr. Lin tomorrow night, and she said to help me work and find a way, the day after tomorrow! She seemed to know what Song Yang wanted to say, and agreed shyly.

"Yay, that's great! Oh, I almost forgot, I'm going to teach Principal An's daughter a writer at seven o'clock tomorrow night......"

Back in the cold room opposite, Song Yang was excited and didn't sleep all night. I don't know how many times I smelled my hands that I didn't want to wash at night, and it seemed that the fragrance was still there.
