I, my father-in-law, set off a frenzy of public examinations in ancient times

Chapter 1 Time Traveling, But Light the Sky Lantern
Guan and Jun stayed up all night again, and it was already late at night after preparing materials for tomorrow's meeting of the two committees.

When she finally opened her eyes after a good night's sleep, an alarm sounded in her mind:

I'm going to be late for the meeting, I have to go to a strawberry planting rural cooperative to cut the ribbon at noon, and I have to inspect the school's nutritious meals in the afternoon... Huh?

At this moment, Guan Yujun realized that she was kneeling with a group of men on the blue-gray floor tiles, and their figures in Hanfu were projected on the bare ground:
Most people wore straight skirts, and the leader wore a crimson round-neck gown.

I seem to have seen this ground in the Forbidden City, and one year the civil servants took this question, asking:
Which brick kiln was used for the floor tiles used in the Forbidden City built during Zhu Di's period?

A. Suzhou Lumu Brick Kiln B. Badaling Great Wall Brick Kiln

C. Tangshan Dalingzhai Brick Kiln D. Zhejiang Shaoxing Yue Kiln
It's a pity that she chose the wrong question and missed the interview by one point.

Later, she also studied it specifically, and the floor tiles in the Jinluan Hall are also called "golden bricks".

The bricks produced by Suzhou Lumu Brick Kiln are fine and dense, without holes, and there is a sound of gold and stone when knocked, which can effectively prevent assassins from digging tunnels for assassination;

But it is a pity that this firing process has been lost...

Thinking of this, Guan Yujun reached out and knocked on the brick, hey, if there is a sound of gold and stone, then this brick is real... huh?

Guan Yujun raised his head slightly in cold sweat, and saw above the nine layers of jade steps, the first thing he entered was a huge Xuande furnace made of copper with silver, cloud and dragon patterns;

The censer keeps emitting green smoke, which smells a bit like ambergris, although it smells good, it is a bit too strong;

Then came the Emperor Seat Dragon Chair. The people on the dragon chair seemed to be young, and their faces in the hazy smoke revealed a light whiteness, like beautiful jade wrapped in mist.

It's nothing more than the hazy beauty like "mountains wiped with clouds".

The young man was stepping on the dragon chair unrestrainedly, leaning on the huge pillow beside him;
Even through the smog, Guan Yujun could feel the young man's falcon-like gaze falling on their kneeling backs, making people feel like a light on their backs.

"Why, can't you count it?

That being the case, I will see you at Caishikou tonight, and it is due to your loyalty to be able to illuminate the four corners of the capital in the form of 'lighting sky lanterns'~"

When Guan Yujun heard this, he didn't think deeply about it, but felt that his voice was hushed and lingering, like well water, so cold for a day.

It sounds good, but it is also like a cold spring flowing through the body, every pore exudes a chill, making people clear...

Then, Guan Yujun understood the meaning behind the boy's words...

Lighting the sky lanterns... No, I wouldn't have traveled to the evil feudal dynasty...

As if to answer her guess, the old man in scarlet robe kneeling at the front, Jishou:

"Your Majesty! The old minister refuses to accept it! Could it be that the whole clan is required to bear the disaster of extermination just because of the old minister's unintentional mistake?

With his life as a guarantee, the veteran has absolutely no selfishness in the arrangement and reporting of the eight servants of the Xing, Hu, Li, and Bing departments!
The sage asked the veterans to arrange three, three, and two assistants in the morning, middle and evening respectively, and the two assistants in the same department should not be arranged to report at the same time;
I don't know anything about the fact that the two assassins got together. I can only say that there is no coincidence, and I hope that the Holy One will see clearly!
If the sage must blame, please only punish the old minister, the family will not be as bad as the disaster..."

In the end, the old man burst into tears, and both Guan and Jun's hearts were softened by his crying: What's going on with this stupid king, who would know that the assassin is still in the mix! ...

"Old man, what are you talking about! I just want to ask you how many ways to arrange the order of the eight people's debriefing. What are you talking about?
It seems that you are stubborn, come here..."

The young man at the top stood up irritably, and Guan Yujun was able to see his whole appearance: he was only wearing a lake-blue Taoist robe, no hat, and no crown or hair.

The raven-feather-like black hair was only draped unruly, which made his complexion whiter, and his complexion seemed to be more gloomy and deep.

He just waved his hands casually, and the brocade guards in flying fish suits who had been waiting by the side like wolves and tigers rushed forward, and each of them lifted up two Guan clan members who were kneeling on the ground, and was about to drag them out...

Fog Grass!Come on!Going to die immediately after time travel?
Guan Yujun lost his composure for a moment, amidst the wailing and wailing in the hall, he yelled angrily: "A total of 820 four kinds!"

After shouting, a needle drop can be heard immediately.

The young man who had already turned around raised his eyebrows as black and thick as his hair, and said to the old man who had just spoken with a half-smile:

"Old man, you still said that you didn't lie! Your own son said that there are 820... [-] [-] four?! You can't be trying to cheat on me, can you?"

Han Yin didn't show it on the first face, and still had a look of indistinguishable emotions, turning his eyes to Guan Yujun; but he kept lying in his heart:

Fuck, is this bastard a deliberately made up number in order not to die?How come there are zeros and wholes? !There are actually more than 1 kinds? ...

Guan Yujun said that this kind of permutation and combination problem is all about sprinkling water, and she can figure it out in her head without even using a pen:
It is known that there are four ministries of punishment, household, rites, and soldiers. Two servants in each department are assigned to report on their work, and three, three, and two are arranged in each of the three time periods of morning, noon, and evening. Arrange for debriefing at the same time period.

How many different arrangements are there for the order of the eight people's debriefing?
Answer: Gradually consider the order of debriefing in the three time periods of early, middle and late:
上午需要从4部中选3部，每部各选1位侍郎进行述职，有C34 C12 C12 C12 A33=192种;
下午需要从上午已选3部中选2位侍郎，再从上午未选的1部中选1位侍郎进行述职，有C23 C12 A33=36种;
Finally, sort the remaining 2 servants in the evening, there are A22=2 types;
Finally, 192*36*2=13824 kinds are obtained.

Guan Yujun's heart was beating up and down, and he just stared at the dog emperor above him.

Han Yinchu looked at the little man surnamed Guan staring at him frankly, and asked the question "How did you figure it out?" in his throat several times, but finally he didn't ask.

It's a joke, the emperor of his country, if he asked people about the process of solving it, it would seem too dull and ignorant.

During his lifetime, Grandpa Huang hated others to say that he, the founding emperor, was an uneducated mud-legged straw shoemaker:

Others said he was a reckless hero, a commoner emperor, and he was overjoyed;
But if someone says that he is an illiterate and illiterate "mountain asparagus with a sharp mouth, thick skin and hollow belly", just wait for the punishment of "peeling"!
