Chapter 389 Yang Fugui fell ill

Yang Fugui actually fell asleep while taking a bath.

Fortunately, Yang Daya came over as soon as possible, woke him up quickly, and forced him to eat a large bowl of porridge before letting him go back to bed to rest.

Yang Daya came to the hall with red eyes, "Auntie, I've already made Fugui eat a bowl of porridge. He looks tired and tired. I don't know if he can survive the next exam. He is really suffering!" "

Jiang Ning felt very uncomfortable when she heard that, but she wanted to comfort her, "Everyone is the same. Last year, the Fourth Village was finally carried out. I was so scared that I cried, but what can I do? I have to hold on. !

Let them have a good sleep tonight. We will set off again before dawn tomorrow. Don’t be too nervous. The most important thing is that we prepare everything for them. "

She already knew that Yang Santie’s first room was a toilet room. After surviving such a difficult environment, what else could she not persevere in?

Yang Daya also knew that his younger brother was rushing towards his future, so it was useless no matter how distressed he felt, he could only help prepare things as much as possible.

This night, the three of them slept in a dark sleep. When it was time to get up, there was no movement.

Jiang Ning simply asked his servants to carry them into the carriage, and drove the carriage to the examination room.

It wasn’t until the carriage stopped that the three of them woke up.

Jiang Ning told them: "I have prepared a new set of things for you, and even some more, as well as dry food. This time there are new pancakes and dry noodles, which can be eaten after being brewed with water. They are better than dry chewing for you." It’s better. I hope I have better luck this time and don’t get the toilet number again.”

Yang Santie’s face darkened and he was filled with resentment, “Mom, don’t say those two unlucky words!”

Jiang Ning quickly shut up.

The three of them entered the Gongyuan and began the second exam. This time, Yang Santie was lucky. The place he was chosen was far away from the restrooms and beside the wall of the Gongyuan. When he stuck his head out, he could see half of the sky, and the wind outside was blowing. When we came in, everything in the room was clean and tidy, and everything looked so pleasant.

The paper was handed out, and he filled in his personal information carefully as before, making sure that no mistakes were missed before starting to review the questions. Fortunately, this time, the paper was quite satisfactory and did not give them a warning at the beginning.

Question 1: "How to use astronomical data to calculate the approximate date of the Spring Festival that year based on the sunrise and sunset times of the winter solstice? Please explain."

This question is very similar to the math questions in ordinary imperial examinations. It focuses on theory and is not difficult.

Yang Santie thought about it carefully and replied: "Looking at the astronomical data, the sun rises and the day is short during the winter solstice, and the night is long at sunset. During the Spring Festival, the Yang Qi gradually grows and the days get longer. After the winter solstice, the sun moves across the sky. The degree gradually increases from south to north, so the Spring Festival must be after the winter solstice and before the longest day.

Astronomical numbers are certain. After the winter solstice, the sun travels across the sky and increases by one degree every day. On the vernal equinox, day and night are of equal length. Therefore, counting from the winter solstice to the vernal equinox, the number of days in between is the number of days from the Spring Festival to the winter solstice. After the vernal equinox, the sun travels across the sky and decreases by one degree each day. On the summer solstice, the day is the longest.

On the day of the winter solstice, the sunrise and sunset times have been determined. On the day of the vernal equinox, the sun rises and sets. There is also a fixed number. From these two numbers, the date of the Spring Festival can be calculated. The method of calculation is to first find the number of days from the winter solstice to the spring equinox, and then add it to the winter solstice to get the day of the Spring Festival. "

After answering, he looked at his answer carefully to make sure there were no gaps. He immediately smiled with satisfaction and continued to read the second question.

The title of the second question is "Number theorist, a branch of mathematics. Among them are prime numbers, greatest common divisors, and least common multiples, which are the basics of numbers. Let me briefly explain its meaning and answer related questions."

This question is not difficult, but ordinary people have neither access to nor use of these terms. For some people, they may not understand all the meanings of these terms. If they cannot understand, how can they answer it?

Yang Santie was so excited that he wrote: "Prime numbers are prime numbers. Among a number, the only ones that can be divided by one and itself are called prime numbers. For example, two, three, five, seven, etc. are all prime numbers. The greatest common divisor is the greatest common factor of a number. To find the greatest common divisor of two numbers, suppose that it is repeated until the remainder is zero, then the final divisor is the greatest common divisor.

The least common multiple is the smallest common multiple of a number. To find the least common multiple of two numbers, there is the prime factorization method. Decompose the two numbers into prime factors and multiply the highest powers of each prime factor to get the least common multiple.

If you ask ‘find the greatest common divisor of two given positive integers’, you can find it by the euclidean division method. If the question is 'Find the greatest common divisor of two given positive integers and find the least common multiple of two given positive integers', you can find it according to the prime factorization method.

This is the basis of number theory, and scholars should study it in depth. "

The third, fourth, and fifth questions all test similar mathematical concepts. The answers are more subjective, but as long as you understand the meaning, it is not difficult. It is even easier than the first test. But this test has ten questions, and the next five questions It involves calculations, and from easy to difficult, there is also a chicken and rabbit in the same cage problem.

He spent one day answering the first five questions. After writing, he stopped writing immediately. When the paper was dry, he put the paper away and took out his own dry food.

He thought that what his mother-in-law had prepared for him this time was a dry and hard pancake with chopped green onion, but he didn't expect it to be a soft pancake that looked like a steamed bun. He didn't know what it was, but he just thought it tasted great and he could eat it in one go. , almost full.

Taking advantage of the cool night breeze, he quickly lay down to sleep.

In the next two days, all his energy was focused on the next five questions, and he did not finish answering them until the paper was about to be handed in.

After putting the papers away, he left the examination room as quickly as possible.

Jiang Ning saw that he was the first to come out, and he was in good spirits, and his expression became much brighter.

Behind him are Yang Erdan, Liang Shaoqian, and finally Yang Fugui.

Others were better, but Yang Fugui looked a little pale.

Jiang Ning immediately focused all his attention on him. When he returned to the villa, he asked the housekeeper to find the doctor to check Yang Fugui's pulse and prescribe medicine.

Yang Daya was so distressed that she burst into tears and ran around.

Yang Fugui was lying on the bed, feeling guilty, "Sister, I'm sorry, I guess I won't be able to take the exam again."

Yang Daya couldn't hold back and cried loudly, "If you can't take the exam, you can't take the exam. What's the point of being sorry to my eldest sister? Anyway, you have already won the title of scholar, and you are more powerful than Qian Wen. I will definitely be happy even if I am Izhi. "Besides, you are still so young, you still have a chance to take the exam, why are you holding on?"

"Your eldest sister is right!" Jiang Ning led the maid into the house carrying some supplements and persuaded: "Fugui, you are already very powerful. Even if you wait for another three years, you will only be sixteen years old. If you pass, say It doesn’t matter if you are a child prodigy!

Please relax and have a good rest. Don’t think too much about other things. Also, I haven’t let anyone inform the village about your passing as a scholar. I even wrote a letter to the Ping’an County Magistrate to cover it up. I’m afraid your father will have another baby if he finds out. The thoughts you shouldn’t have are causing trouble for you.

And your third uncle and your third aunt, they put their hope in Lai Gui, and pointed out that Lai Gui will be able to pass the examination and go back to the country in the future. Even if it doesn't work, he will have to take the exam to become a scholar. If they know that you are now a scholar, I'm afraid they will feel bad in their hearts. It will also be uncomfortable.

When you grow up in three years and want them to know, it’s not too late to speak up yourself. "
