At the same time, the expert doctor has also come to Yuezhou city. As soon as he entered the city, he found that the doctor with a medicine box on his waist was running around. He didn't know what happened in the city. He didn't think much. He was tired all the way, so he wanted to find a teahouse to have a cup of tea to quench his thirst.

A moment later, the expert doctor came to a small teahouse. As soon as he got to the door, he saw a group of people gathered together. He didn't know what he was doing. Without much thought, he found a place to sit down and prepare to call a cup of tea to quench his thirst.

"On that day, the president of Bailu college was in the residence, fighting with all the students. The scene was really magnificent. The president stood on the table and talked loudly, so majestic..."

A voice came to the expert doctor's ears from the crowd, and he heard it curiously to see what happened there, how so many people gathered, and what they were doing.

When I came closer, it turned out that a man in a black coat, with a small beard and a folding fan in his hand was standing on the table talking with interest. More and more people around approached here. It turned out that this was a storyteller telling a story here. He was more interested in stopping and watching. The storyteller continued.

"Did you know that the dean of White Deer College is going to open a college in Jiangnan to prepare for enrollment. He has set two questions as the criteria for enrollment. If he can solve them, he will be exceptionally admitted by White Deer College. The first one is the test of pheasant and rabbit in the same cage to find out how many pheasants and rabbits are?"

When they heard this, they took a breath. Hiss --

"No wonder their children run after pheasants and rabbits every day. They don't know what to do there?"

"Yes, yes, my nephew stared at the pheasant and the rabbit in a daze every day. I thought the child was stunned!"

"What's the problem? How can you count it?"

When the expert doctor heard this, his heart was shocked and he couldn't help bursting out: "this is the Mathematical Olympiad in Jiugong arithmetic!"

"What?"

"Mathematical Olympiad?"

"What is Mathematical Olympiad?"

"What are you talking about, old man?"

This matter.

Everyone looked puzzled.

Just about this, the storyteller on the stage suddenly changed his look and hurriedly asked, "this old gentleman, what you said is the nine palace flying arithmetic that only those princes, ministers and princes can learn?"

"Hiss --!"

"What the fuck is this?"

"Sir, can you be more clear? I paid for your tea today, but you have to tell me what the nine palace arithmetic and the Olympic mathematics have to do with this young rabbit?"

"Yes, if you make it clear, we'll invite you even if you go to the building today!"

"If you don't make it clear, we'll have to let you go out sideways today!"

All the people were confused and shouted about it.

When the storyteller heard the speech, he was suddenly sweating and quickly hugged his fist and bowed to the people: "you, don't worry! Listen to me slowly!"

"This Mathematical Olympiad is a kind of profound knowledge. Every family has farmland. How much is the annual output and how many seeds are expected to be sown, such as how much can be produced per mu of land and how much is the income? Is it a headache for ordinary people to calculate?"

Everyone nodded in agreement, and the storyteller then said: "However, if you learn the nine palace arithmetic, these things can be solved easily. Today's ministers and senior officials have to face how many mu of land they have to face. They use the nine palace arithmetic to calculate the income and expenditure. They want to ensure the in and out accounts of the Datang national treasury, but after the nine palace arithmetic, those things become very simple."

"I see. It turns out that President Zhang Feng is really considering for the common people. He even taught everyone the nine palace arithmetic that is only available in the imperial palace!"

"I have to learn such a good thing. I have to let my son learn it and sign up for it!"

For a time, the people shouted to let go.

"What is this pheasant rabbit cage? Explain quickly!"

"Yes, yes!"

The storyteller looked at the expert doctor with an embarrassed face, bowed with both hands and said, "old Sir, I don't know how to solve this problem. You know Jiugong arithmetic, and you must also know how to solve this pheasant rabbit cage?"

The expert doctor said confidently, "I used to sit in the imperial palace of Chang'an before. Naturally, I know the nine palace arithmetic. As for the pheasant and rabbit in the same cage, I don't know. However, you can go to Chang'an White Deer College and ask those students. Those students must know how to answer."

"What? Isn't it crazy to go to White Deer College now? It's such a long way!"

Seeing this, the storyteller continued: "take it easy. As I said before, the president of the White Deer College will set up a college in Jiangnan, and take charge of food and drink, without charging any tuition fees. If you have a skill and outstanding performance, you will be arranged to find a job in the work department or the official Department of the imperial court."

"What? Free?"

"Can you still find a job in the imperial court? Really?"

"I'm going to let my son go. Maybe something will come out and honor my family!"

For a time, everyone was talking and sighing with President Zhang Feng.
