From Han Fei's point of view, the banquet of the Eastern Han Dynasty was quite advanced in terms of hygiene. Each person had a seat and a separate meal system. His task was to take care of the guests during the banquet. After all, it was a male guest, and it was inconvenient for a maid to attend.
This was much easier than being a hotel waiter. The salary was much higher, and they could listen to celebrities talk about the world's major events to broaden their horizons. When they went back, they could even brag. No wonder commoners wanted to work for big families. As Cai Yi and the others chatted and drank, Han Fei knew who these four people were from their conversation. The first person on the left was General Lu Zhi. Opposite him was Yi Yang Biao from the capital. The person in front of him was the remonstrant doctor, and opposite him was Zhang Xun. These few were all famous celebrities in the world, and when Emperor Xian was in trouble, each of them was an important minister.
"Brother Boyi's handwritten 'Xi Ping Stone Scripture' has been completed and is widely praised by the world.”Yang Biao laughed. "Yes, yes. It took several years to complete this stone inscription, and now it has been erected outside the Imperial College. I've heard that students from all over the world go there every day to observe.”Lu Zhi said. Cai Yi smiled modestly." This is all your credit. How can I take it?"”After three rounds of wine and five dishes, they began to chat after finishing their business. Zhang Xun said," Brother Bo Yi, I've heard that you like mathematics. A few days ago, I found a person who is proficient in mathematics. This person is very proficient in the Nine Chapters of Arithmetic. I admire you very much. I saw your talent and brought it over today.”
In ancient times, mathematics was one of the main schools of thought in the Book of Changes, the first of the Six Classics. Arithmetic was included in mathematics, and it was also a serious knowledge in ancient times. "Oh, but please come up." Cai Yi likes academic exchanges and smiled." A moment later, a thin middle-aged man came up. Han Fei saw that this person's eyes were darting around, and he could tell that this person did not seem like a proper person.
This person walked to the center of the hall. Although he was white, he was not afraid. He bowed and said, I am Wu Ji, Wu Chunian. Greetings, sirs.”"Mr. Wu Ji, there's no need to be so polite. I heard that you're proficient in arithmetic?”As the host, Cai Yi said. Arithmetic was used in everything from military formations to internal affairs statistics to business transactions and bookkeeping. It was a serious skill. People who were proficient in arithmetic were rare talents. Lu Zhi and the others stroked their beards and sized this person up. Seeing how elegant he was, he nodded secretly. "Lord Cai, this student has a question. Cai Yi didn't expect this person to be so blunt and frowned slightly.
"It's fine to say it," he said slowly. "Everyone here is a leading scholar of the Great Han Dynasty. I will use books as the topic. Student A and Student I will go to the shop to buy the same new book. Student A will use three-fifths of the money he has brought to buy it, and Student I will use two-thirds of the money he has to buy it. The money left by A is five wen more than what has been left. How much did it cost for each of them? How much is the book?" Wu Ji said proudly, his eyebrows raised. As expected, they were here to cause trouble. It was inevitable that someone from Cai Yi's talent would cause trouble. Han Fei wanted to see how Cai Yi would answer.
Huh?
Lu Zhi and the others frowned. At this moment, they could tell that this person was using this opportunity to become famous.
He said to the servant beside him," Then, give me the pen. I'll check it. After an incense stick of time, Cai Yi, who was writing at full speed, frowned. This question sounds like an fried egg, but it's very complicated when I calculate it." This matter will spread throughout Luoyang tomorrow, perhaps even the whole world. The reputation of me, Wu Chuji, hehe. Seeing that Cai Yi couldn't solve it, Wu Ji said,"Lord Cai, if you can't do it, I can help you solve your doubts.”Han Fei saw that the Luoyang paper on Cai Yi's table was densely covered with countless seal characters. This big man did not add any symbols, did not add any numbers, and did not have any mental calculations.
"Wait!" Han Fei said. Han Fei was angry that Wu Chunian had taken the opportunity to become famous, so he walked to the hall. Wu Ji wanted Cai Yi to ask him to explain, so he said loudly,""Who are you?" "No problem. I'm Han Fei, Han Zijin," Han Fei said with a smile. "Hmph, frog in a well, listen up!”Han Fei shook his long sleeves and said,"Shejia brought X coins, and already brought Y coins. The result is: 3/5X 2/3Y 5." "In the end, X is equal to 50 coins, 45 coins have been brought, and 30 coins have been written.”Han Fei thought to himself that this was a stupid question. He flicked his sleeves and said disdainfully,"Brat, am I right?" Wu Ji began to panic and shouted,"You, how did you calculate it?"”"Am I right?" Han Fei still smiled.”Wu Ji was already sweating profusely in the face of Han Fei's questioning. He was no longer as calm as before.”
