Seeing the reactions of Chen Zairong, Chen Wanrong couldn't help but smile. If they knew that they had read much more books than Chen Zairong, they would definitely not be so shocked. It's no wonder that a person who had never been to school and was illiterate could have such knowledge and guide someone as smart as Chen Zairong to have a pair, and another person would be as surprised as Chen Zairong.

"Wanrong, how can you learn it?" Chen Wangshi was the first to wake up. She was shocked too much, which made her throat dry and her voice became much sharper. She no longer had the gentleness she used to, and she sounded a little harsh.

"Mom, I will just mention a few words. This is just a clever mind. I thought of it myself." Chen Wanrong decided to use humility to attack the sloppy eyes.

The ancients regarded couplet sentences as a science, while we modern people talked and enjoyed it as fun. For example, "Boys, girls, poor scholars, live endlessly; first love, passionate love, extramarital love, reluctance to leave", "The wind is blowing, rain is falling, I am waiting for you to call back; I live for you, die for you, and wait for you for the rest of my life." Chen Wanrong also participated in a lot of funny couplets. Although he could not enter the elegant hall, he could at least cultivate his intelligence and enjoy it. In addition, his extensive knowledge has been living in society for many years, and he has seen a lot of human relationships and worldly ways. When he heard Chen Zairong talk about it, he thought of it.

On the other hand, Chen Zairong is only sixteen years old and has not been well-informed in the world. It is indeed difficult to make such a pair. However, he is extremely smart. Chen Wanrong thought of it as soon as he mentioned it. Chen Wanrong's words were not unreasonable. Chen Zhen coughed dryly and scolded Chen Wang: "What are you talking about? Wanrong can't match the pair before he hasn't read a book? He hasn't eaten pork, and hasn't seen pig run away?"

Chen Wangshi gave him a blank look: "You know, show me one."

"You go to heaven, I go to the earth, I'm facing each other." Chen Houshi blurted out without thinking.

This was just nonsense, but it made Chen Wang laugh, burst out laughing, and gently pinched Chen Laoshi's back.

Chen Wanrong gave an exam to Chen Zairong: "Zairong, Mr. Wu published this first couplet to tell you that knowledge is everywhere. Pay attention to everything and your knowledge will improve."

"Well! Brother, I understand." Chen Zairong nodded violently, very excited. After thinking about it, he said, "Brother, can you do math problems? Mr. Wu also gave us a math problems, but I didn't think of them." He looked at Chen Wanrong with great anticipation.

Originally, he asked Chen Wanrong for help with a try-and-seek mentality, but unexpectedly, after Chen Wanrong's suggestion, he really came out. Chen Zairong couldn't help but be very excited and decided to ask Chen Wanrong for help again.

A great scholar like Wu Jing is knowledgeable and has a wide range of knowledge. It is normal for him to know how to do mathematics. Chen Wanrong is not surprised at all. Although Wu Jing has never met, Chen Wanrong is very proud of his character and style. He naturally needs to get a glimpse of the questions he gave, and asked: "What question?"

Upon hearing this, Chen Zairong couldn't help but be happy: "Brother, this is a numerical method for calculating monks. The towering ancient temple is in the mountains, and I don't know how many monks there are in the temple. There are 364 bowls, and it happens to be used up. Three people eat a bowl of rice, and four people drink a bowl of soup. Can you calculate, how many monks in the temple in the mountain?"

Our ancestors had a deep literary foundation. The mathematical questions and writing poems in their debut were all used in the rhymes and corners. They read them easily, as if they were reading Tang poetry. They sounded pleasant and could not be admired.

"Mr. Wu is broad-minded!" Chen Wanrong praised Wu Jing.

Chen Zairong is sixteen years old, which is equivalent to our current junior high school student. Moreover, he is a student of poetry and books, and does not specialize in math. This is equivalent to our current liberal arts student. This question is a one-time equation, which is very suitable for a junior high school student as a thinking question.

In this case, it is a very obvious thing to stump others. With Wu Jing's knowledge, he can even get a question that is ten times more difficult than this, but he did not give a more difficult question to show his talent, but instead gave a suitable question. Chen Wanrong admired his mind.

Chen Zairong was fascinated by Wu Jing. Although he didn't understand why Chen Wanrong praised Wu Jing, he still agreed with Chen Wanrong's words from the bottom of his heart: "Who said no?"

Chen Wanrong began to solve the problem: "Three of these monks eat a bowl of rice and four drink a soup. So how many bowls will each monk use?" Chen Wanrong has figured out the answer. In order to cultivate Chen Zairong's thinking ability, Chen Wanrong did not report it in one mouthful.

Chen Zairong rolled his eyes for a while, then hesitated and said, "Three One plus Four One is seventh of the twelve. Brother, is there such a bowl?" Three One is one third of our modern age, Four One is one quarter, and seventh of the twelve is seventh of the twelve. The ancients did not say a few percent.

In his imagination, eating can only be done by one bowl alone, so how can you use seven out of twelve bowls? This is the key to this question. Chen Wanrong explained to him: "Don't treat it as a matter of life, this question requires a proportion."

As soon as the bend turned, other problems were solved. Chen Zairong excitedly grabbed a piece of firewood, wrote the word "光" on the ground, and then wrote the word "光" in front of the word. The next step is to put the word on the left, put 364 and 722 on the right, and then write "光" on the ground.

Our ancestors also used unknown numbers to solve problems, but not XYZ, which we are familiar with, but used some, some, some, some, some, some, some, some, some, some, some, some, some are equivalent to the unknown number we use now.

The answer was 624. Chen Zairong was very excited. He looked at the words on the ground and kept patting his forehead. He was very regretful: "Brother, it turns out that's how it was calculated. I always thought there were no three or four or four, so I didn't expect it." (Note: I didn't calculate this thinking question when I was in elementary school. The reason was the same as Chen Zairong. I didn't turn this corner and was associated with life. I didn't expect it to be just a proportion. Not only did I not solve it, but no one in our class solved it. I clearly remember that when the math teacher finished solving the problem, there was a sound of surprise in the classroom. The little girl couldn't help but cover her mouth.)

"Wanrong, can you still solve mathematical problems? Old man, Wanrong is becoming more and more capable." Chen Wang, who has always been steady, no longer has the steadiness he usually holds. When he touches Chen Honest, he hurriedly praised Chen Wanrong.

"Super capable, really capable, very capable!" Chen Chen couldn't help rubbing his hands, smiling so hard that his mouth could not be closed. His simple language exuded endless joy. Look at Chen Wanrong and look at Chen Zairong again. The eldest son was smart and capable, the second son was smart and clever. The two sons stood together, which was endless hope. No matter who was a father, he would smile without wrinkles when he was in this relationship.

Chen Zairong said happily: "Brother, every March 3rd, our school will take us to the Wei River for a trip. Then we will recite poems and verses and sing them together, which is very lively. The previous few times, my family gave me money. This year, I don't have to spend my family's money, so Mr. Wu has to pay it."

What he was happy about was not that he saved money for his family, but that he was favored by a great scholar like Wu Jing. Being favored by a great scholar like Wu Jing is a supreme glory, and anyone else would be excited.

The capital of the Tang Dynasty was Chang'an, which was located on the shore of the Wei River. Every spring, people traveled would gather in the Wei River to take a spring outing, which was similar to our current spring outing.

Wu Jing was knowledgeable, had a very good character, did not show off his knowledge, and gave the students a moderate question, which made Chen Wanrong admire him from the bottom of his heart. However, Chen Wanrong was a little curious and wanted to try how deep his math skills were. After thinking about it, he said, "No matter how grateful, I have a question, I will read it to Mr. Wu to know and ask him to solve it."

It is a great pleasure in life to be able to stump a great scholar like Wu Jing, and anyone will enjoy it. Although Chen Zairong has no bad intentions to make Wu Jing look ugly, it is also a pleasure to make him feel troubled. He hurriedly asked, "Brother, you must have a difficult point. If you don't have a difficult point, don't make it. Mr. Wu's."

This made sense. Chen Wanrong immediately changed his mind and decided to come up with a difficult question. After a moment of change, he immediately had an idea: "My question is about planting trees: there are twenty trees, four trees in each row. How to plant them to get the most number of rows? Please ask Mr. Wu to draw a picture."

"Brother, isn't this difficult?" Chen Zairong didn't know that this was a world-renowned mathematical problem. It has stumped countless mathematicians over the past few hundred years, and he thought it was a very simple problem.

At first glance, this question is nothing big. After thinking about it carefully, I realized how difficult it is. Even the great mathematician Gauss was stumped. Chen Wanrong did not explain much: "Just say you can tell Mr. Wu, Mr. Wu will understand." Wu Jing may not be able to solve this question, but with his vision and knowledge, he can see how difficult this question is. Chen Wanrong believes in this.

"Brother, I remember." Chen Zairong nodded in agreement.

Chen Laoshi's surprise screamed: "Look, there is hotpot in the pot."

Chen Wanrong quickly turned his head and saw that the water in the pot was almost gone, and a lot of hot alkali crystals appeared in the pot. Looking at the white crystals, Chen Zairong almost jumped up excitedly. He pointed to the pot and shouted happily: "Really, really, there is hot alkali in the water!" This was the first time he had seen hot alkali in the water with his own eyes, and he couldn't do it either if he was excited.

Chen Wanrong hurriedly removed the firewood in the stove and evaporated slowly over low heat. After almost half an hour, the evaporation was completed. After the alkali cooled down, he wrapped it in oil paper and tied it tightly to prevent the irrigation. Only then did he get it done.

Looking at a large bag of hot alkali, Chen Houshi was extremely happy. He couldn't stop rubbing his hands, as if it was white silver. Chen Zai Rong was still unfulfilled and stopped going to school, and he stopped living on the package to caress his mom.

After the passion cooled down, it was already dark, and the family rushed to the stove to cook. Even Chen Laoshi, who had never entered the stove, helped him to help him hold firewood and raise fire. Chen Wanrong cut vegetables and cooked vegetables, and everything was good, making Chen Wangshi so happy that he looked at Chen Wanrong and laughed as if he was ten years younger.
