Chapter 344 Chapter Thirteen

Grandpa bluntly said: "Yes. According to the 'count' you gave me, such as the date and time, I can be sure that she was pregnant that night and gave birth to a child shortly after. It's just that I am wondering, how did you No sense at all? Ordinary snakes give birth to snake eggs, and then the baby snakes break out of the snake eggs. But Zhuyeqing is a viviparous snake that reproduces like a human. Then, she will gain weight for at least a period of time. And his temperament has changed a lot." I never thought that Grandpa would have a certain understanding of Zhuyeqing.

Zhang Jiu shook his hands in fright, and half of the tea in the teacup was spilled, "Master Ma, you said she gave birth to me? No way? I am a human, and she is a snake! We, how could we... how could it be possible Will it be like that?" His sissy made me wonder whether it was surprise, joy or embarrassment.He said he was shocked, but his face was happy; he said he was happy, but his eyes were open and his mouth was open with a look of horror; Grandpa said: "The result of the calculation is indeed like this. Could it be that I made a mistake?" Grandpa hesitated at this moment, and he looked at his withered and yellow fingers again, as if doubting those fingers.This is a rare performance of grandpa.

Zhang Jiu calmed down and asked, "Master Ma, can numerology... also be counted as this?" Grandpa said: "Not only can this be counted, if you give me a more specific 'number', you can also count whether you have a boy or a girl." I interrupted and said, "Grandpa, why haven't I heard you say it before?" Grandpa smiled and said: "In ancient times, there were many families who favored sons over daughters. Even if we knew it, we would not say it. Otherwise, how many daughters would be shot down by their parents before they were born." I know that the "we" that grandpa said refers to those people who knew alchemy in the past.In fact, it is more than ancient times. More than ten years ago, when the family planning was tightened, many "super-birth guerrillas" fled their hometowns to give birth to a male doll who could "inherit the incense".The neighbor next door to ours gave birth to four daughters and was not willing to let it go. They didn't come back from other places until the fifth was born as a boy.And when the couple returned to Changshan Village with their five children in their arms, they found that their house had been demolished by the Family Planning Office.

At that time, the people in the Family Planning Office were very fierce. When they met the "Super Birth Guerrillas", they were brutally tied up and escorted to the hospital for a ligation operation.If someone's family has "excessive birth", the family planning office will raid his home and demolish his house.Although it seems that it is not humane to force people to be sterilized to this point, these things were commonplace at the time. Therefore, it is reasonable for Grandpa not to say some things so easily. Zhang Jiudao: "I've heard that numerology can be applied to raising snakes and farming, but I haven't heard that numerology can also predict these things."

Grandpa looked at me, then at Zhang Jiu, and asked, "Do you know "Sun Tzu's Mathematical Classics"? It is equivalent to an ancient mathematics textbook. Do you still use it in your school now?" Zhang Jiu shook his head. But I know a thing or two about "Sun Tzu's Mathematical Classics".This book was written in the fourth or fifth century, and the author's life and writing date are unclear.The current version of "Sun Tzu's Mathematical Classics" consists of three volumes.The scroll describes the vertical and horizontal system of counting numbers and the rules of multiplication and division. The volume gives examples to illustrate the calculation of fractional algorithms and the calculation of Kaiping methods.Question 31 of the second volume can be said to be the ancestor of the "chicken and rabbit in the same cage" question in later generations, which was later spread to Japan and became "crane and turtle calculation".The book describes it like this: "Today there are chickens and rabbits in the same cage. There are thirty-five heads on the top and ninety-four feet on the bottom. Ask the chickens and rabbits how much? The meaning of these four sentences is: how many chickens and rabbits are in the same cage?" Counting from the top, there are thirty-five heads in a cage; counting from the bottom, there are ninety-four feet. How many chickens and rabbits are there in each cage?"

When it comes to "chicken and rabbit in the same cage", I believe anyone who has been to elementary school or read mathematics books knows it.When I was in elementary school, I was often confused by these derived questions.These problems often appear in Mathematical Olympiad.At that time, I was very troubled by these problems, and I could even say that I hated them to the bone, so I was deeply impressed. But this is a book about mathematical calculations. I don't know how grandpa suddenly mentioned this book has anything to do with the problem of having boys and girls. Grandpa naturally wanted to mention that "Chicken and Rabbit in the Same Cage" came from "The Grandson's Mathematical Classics". Grandpa Zhang Jiujing made a point, and finally said "Oh" and nodded repeatedly.I believe that Zhang Jiu's head is also thinking: what is the connection between this addition, subtraction, multiplication and division and fertility?

Grandpa naturally knew what we were thinking, he laughed and said, "Most of you only know about the chicken and the rabbit in the same cage, but you don't know what the last question of "Sun Tzu's Mathematical Classics" is." "The last question?" Zhang Jiu and I asked in unison. Grandpa had expected that we didn't know, so he took a sip of tea with a calm expression, and said, "The last question in "Sun Tzu's Mathematical Classics" is this: There is a pregnant woman today, and she is 29 years old. It is hard to know in September. Born? The answer is: to give birth to a male. The technique says: set forty-nine plus difficult months, subtract the year of travel, and divide the rest by sky by one, earth by two, people by three, four seasons by four, five elements by five, and six laws Six, seven stars divide seven, eight winds divide eight, and nine provinces divide nine. Those who are inexhaustible, those who are odd are men, and those who are even are women.”

Both Zhang Jiu and I were confused and confused.But the last two sentences can know that after some calculations, if the remainder is an odd number, then the child born is a boy; if the remainder is an even number, then the child born is a girl.Because I don't know much about the five elements, six laws, seven stars and eight winds, so I don't know what kind of algorithm to go through in the middle.But it can be known that grandpa predicted that Zhuyeqing was pregnant through this magical number technique. Seeing my grandfather talking about numeracy again, I quickly asked, "Grandpa, since Zhuyeqing gave birth to a child for him, why didn't she tell Zhang Jiu?"

I reminded Zhang Jiujing, and immediately woke up from his obsession with ancient numerology, and asked urgently: "That's right. Master Ma, why did she hide it from me? Why don't I feel strange?" "This..." Grandpa turned the teacup in his hand and muttered. "What's so hard to guess!" Grandma came in from the door, her hands as cold as carrots.The three of us immediately turned our attention to the elderly grandma.A gust of wind blew up, and the sheets washed in rice soup rustled behind grandma.
