Guan Youjun stayed up all night, and it was already late at night after preparing the materials for tomorrow's meeting of the two committees.

When she finally opened her eyes after a full sleep, the alarm bell sounded in her head:

If it's broken, it's broken, it's going to be late for a meeting, and at noon I have to go to a strawberry planting rural cooperative to cut the ribbon, and in the afternoon I have to go to inspect the problem of nutritious meals in schools...... Yes?

Guan Youjun realized at this time that she was kneeling down with a group of men on the blue-gray floor tiles, and their figures in Hanfu were projected on the light:

Most of them wore straight shirts, and the leader wore a crimson round-necked robe.

I seem to have seen this ground in the Forbidden City, and one year I took this question in the civil servant test, asking:

Which brick kiln did the bricks used in the Forbidden City built during the Zhu Di period come from?

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 specialized in research, and the floor tiles in the Jinluan Hall are also called "golden bricks".

The bricks produced by Suzhou Lumu brick kiln are delicate and dense, broken without holes, and there is the sound of gold and stone when striking, which can effectively prevent assassins from digging tunnels for assassination;

Unfortunately, this firing process has been lost......

Thinking of this, Guan Youjun also stretched out his hand and knocked on this brick, hey, if there is really the sound of gold and stone, then this brick is real...... Huh?

Guan Hejun raised his head slightly in a cold sweat, and saw that above the nine-fold jade steps, there was a huge Xuande furnace with a wrong silver cloud dragon pattern copper;

The incense burner kept coming out of the green smoke, and the smell was a bit like ambergris, although it smelled good, it was a little too strong;

Then there is the dragon chair of the emperor, the person on the dragon chair does not seem to be very old, and the face in the hazy smoke reveals a light white, like a beautiful jade entangled in fog.

When you think about it, the hazy beauty of "mountains and clouds" is nothing more than that.

The young man was stepping on the surface of the dragon chair with an uninhibited foot, leaning on the huge pillow at his side;

Even through the smoke gate, Kazu-kun could feel the young man's eagle-like gaze fall on their kneeling backs, making people feel like they were on their backs.

"Why, can't you count it?

That being the case, you will see you at the vegetable market tonight, and you can use the form of 'lighting the sky lantern' to illuminate the four corners of the capital, and you are also loyal~"

When Guan Youjun heard this, he didn't think deeply about it, but felt that his voice was suffocating, like well water, soaking in the stars of the day.

It sounds good, but it is also like a cold spring swinging around the body, and every pore exudes a chill, which makes people's minds clear......

Then, Guan Youjun understood the voice of the previous young man......

Light the sky lantern...... No, I won't have crossed over to the evil feudal dynasty, right......

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

"Holy! The old minister is not convinced! Is it because of the unintentional mistake of the old minister, but the whole clan has to bear the disaster of extermination?

The old minister vouched for his life, and he was absolutely selfless in reporting on the arrangements of a total of eight servants from the four departments of punishment, household, ceremony, and soldier!

The Holy Lord requires the ministers to arrange three, three, and two attendants in the morning, noon, and evening three time periods in turn, and two attendants in the same department are not arranged to report on their work in the same time period;

The minister didn't know anything about the two assassins getting together, and he could only say that 'no book could be written without coincidence', and he hoped that the saint would know everything!

If the saint must blame, please only punish the sin of the old minister, and the disaster will not affect the family......"

In the end, the old man was in tears, and Guan and Jun were both softened by his crying: what is the matter with this faint king, who knows that the assassin is still mixed in! ……

"Old thing, what a rambling thing! I only ask you how many ways there are ways to arrange the order of the debriefing of these eight people, and what are you doing with all this uselessness?

It seems that you are stubborn, come on......"

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

The black hair like a crow's feather was draped uninhibitedly, and his face was whiter, and his complexion seemed to be more gloomy and deep.

He just waved his hand casually, and the brocade guards in flying fish suits who had been waiting on the side like wolves and tigers stepped forward, and one of them set up two Guan clan people who were kneeling all over the ground, and they were about to drag them out......

Fog grass! Come on really! Immediately after the crossing?

Guan Hejun was not calm for a moment, and in the crying sound in the hall, he shouted with full anger: "There are a total of thirteen thousand eight hundred and twenty-four kinds!" ”

After shouting, the pins fell suddenly.

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

"Old thing, you said you weren't lying! Your own sons say thirteen thousand...... Thirteen thousand eight hundred twenty-four?! You can't be in Kuang Zhen, right? ”

Han Yin's face was not obvious at the beginning, he still looked like he was happy and angry, and he cast his eyes on Guan Hejun; But my heart is constantly lying down:

Damn, is this dog a deliberate number made up in order not to die? How can there be a whole thing?! There are more than 10,000 of them? ……

Guan Youjun said that this kind of permutation and combination questions are sprinkled with water, and she doesn't even need to use a pen to calculate it by mental arithmetic:

It is known that there are four departments of criminal, household, ritual, and soldier, and two waiters in each department are arranged to report on their work, and three waiters are arranged in the morning, noon, and evening three time periods, and two waiters in the same department are not arranged to report on their work in the same time period.

Q: How many different ways are there in the order of debriefing?

Answer: Gradually consider the order of debriefing in the morning, noon and evening periods:

In the morning, you need to select 3 from 4 departments, and each department selects 1 squire to report on their work, there are C34 C12 C12 C12 A33 = 192 kinds;

In the afternoon, you need to select 2 waiters from the 3 parts that have been selected in the morning, and then select 1 waiter from the 1 department that has not been selected in the morning to report on their work, there are C23 C12 A33 = 36 kinds;

Finally, the remaining 2 waiters in the evening are sorted, and there are A22 = 2 types;

Finally, 192*36*2=13824 species are obtained.

Guan Youjun's heart was beating up and down, and he only stared at the dog emperor above.

Han Yinchu looked at the little man surnamed Guan staring at him with a frank face, and circled his throat a few times, "How did you figure it out?" In the end, he didn't ask the question.

Joke, he is a son of heaven, if he asks others about the process of solving, it will inevitably seem too reckless and ignorant.

Before his death, the emperor's grandfather was most taboo for others to talk about him, the founding emperor, as an uneducated mud-legged and straw shoemaker:

Others say that he is a reckless hero and a son of cloth, and he is overjoyed;

But if someone says that he is the kind of "mountain asparagus with a thick mouth and a hollow belly" who has no ink on his chest and is illiterate, he is waiting for the punishment of "peeling"!
