The eldest princess liked the taste after tasting the barbecue, and after tasting some of it, Jiang Han poured tea to relieve her greasyness.

Princess Ning Yue took the teacup, took a sip, and said, "Confucianism says that a gentleman is far away from cooking. Jiang Gongzi was different, and he personally barbecued meat, which really surprised the palace. ”

Jiang Han smiled slightly, and said: "The gentleman is far away from the cook, the gentleman can't bear to see the beasts die, and he doesn't want to listen to the screams and sorrows of the beasts, so he stays away from the cook, but it is not the reason that the gentleman can't cook." ”

The eldest princess said: "These words make this palace more and more curious, what kind of person are you." ”

Jiang Han said: "Jiang Han is a scholar, that's all. ”

The eldest princess chuckled and glanced at the layout in the courtyard: "Do you learn swords?" ”

There was a peach tree in the yard, and there were old and new sword marks on the tree.

"Scholars learn swords to improve themselves." Jiang Han said.

The eldest princess nodded and said, "This palace is here today, and there is really something to ask for. ”

Jiang Han said: "The eldest princess, but it doesn't hurt to ask, the grass people will tell what they know." ”

Princess Ning Yue groaned slightly, and said: "A few days ago, more than 100 countries sent envoys to visit Dayu, and entered a question, the topic was tricky and strange, extremely difficult to solve, and the Manchu Dynasty civil and military forces could not solve it for a while. ”

Jiang Han's heart moved slightly.

Princess Ning Yue continued: "If you want to solve this problem, it's not that you can't solve it, but it takes a lot of time, and the civil and military forces can't solve it that day, and you can't help but be laughed at by more than 100 envoys. His Majesty therefore ordered that this question be added to the Autumn Exam to see who could solve it in Kyoto. ”

Jiang Han suddenly realized, no wonder Qiu Yu suddenly had an extra question.

The eldest princess said softly: "After the Qiu Yu exam, almost all the candidates couldn't solve that question, but only Gongzi solved it. When the chief examiner Wang Zhong told His Majesty the news, the palace was beside him, and he was very curious, so he came this time to ask how the prince solved this question. ”

Jiang Han groaned slightly, this eldest princess is not a vase, Emperor Yu also attaches great importance to it, on the surface, she came to ask herself the solution to this problem, in fact, the emperor wants to know, so he can take the opportunity to show his talent and brush up on a wave of goodwill!

Jiang Han thought of this, and said, "Does Her Royal Highness the princess know the topic of chickens and rabbits in the same cage?" ”

"I want to hear about it." The eldest princess said.

This chicken and rabbit cage is from "Sun Tzu's Sutra", but Dayu does not have this book, or this book has long been lost, and it is normal that the eldest princess has not heard of it, so that she can show her hand in front of the eldest princess...... Jiang Han said: "There are pheasants and rabbits in the same cage today, with thirty-five heads on the top and ninety-four feet on the bottom. ”

Princess Ning Yue frowned slightly, and fell into deep thought.

Qingfeng, the little maidservant girl beside her, also pinched her fingers and counted, but soon her face was embarrassed.

This question is a bit weird!

Jiang Han poured himself a cup of tea, drank it slowly, and waited quietly.

About half an hour later, Princess Ning Yue said, "There are twenty-three pheasants and twelve rabbits. ”

Jiang Han gave a thumbs up and said, "Princess! ”

"I have another question, there is a beast today, six heads and four legs; Fowl, four heads and two legs, seventy-six on the top and forty-six feet on the bottom. Q: What are the geometries of birds and beasts? ”

Princess Ning Yue frowned and pondered, and after another quarter of an hour, she said, "Eight beasts, seven birds." ”

Jiang Han couldn't help but praise: "Her Royal Highness the princess is amazing!" I would like to ask the princess again, today there is a rise in the South China Sea, seven days to the North Sea; The wild goose starts in the North Sea, and goes to the South China Sea on the ninth day. Now the geese are rising, and they ask when they will meet?"

Princess Ning Yue pondered for a quarter of an hour, shook her head, and said, "It's hard to unravel. ”

Jiang Han said: "Because the eldest princess solved the first two questions, it was calculated by hard work, just because the princess was extremely smart, so she calculated extremely quickly." But the third question doubled in difficulty, and the princess couldn't figure it out. ”

"In fact, if you want to solve these three questions, there is a corresponding way."
