Liu De found Zhonglang General Zhidu near a school field in the east of the city, where he commanded the officials to maintain order.

Zhonglang will be this official position, which is more complicated at this time.

The Han Dynasty inherited the Qin system, which basically inherited most of the political design and structure of the Qin Dynasty.

The basic political form of the whole country is almost the design of the Qin Dynasty, and then, the emperors of the Han family in successive dynasties continue to add some of their own understanding and opinions to the crystallization of the political wisdom of these Qin people.

Zhonglang Jiang, the second general of the Qin Dynasty, naturally could not escape the clutches of the Han family.

At this time, there are many theories about the name of Zhonglang General, but there are mainly three: the five senses and the left and right Zhonglang Generals, in the history of the Han Dynasty, called the 'Three Administrations', which are mainly responsible for the personal security of the Son of Heaven and the safety of the royal chariots and court ministers.

And Zhidu is now holding the position of the general of the five senses.

What about the five senses? Therefore, in fact, the current Zhi are all civil officials, not military positions, and their functions and powers are to manage and restrain the Lang officials of the imperial court to assist the imperial historian in rectifying the rule of officials.

However, Liu De knows that Zhidu, the cheap daddy's goshawk, is not only a cool official, but also a famous general with strong military talent.

The so-called 'generals of war, minions of the country' is not just talking, the corpses of the Huns who are full of corpses under the Yanmen Gate are the best annotation of his achievements.

"Ministers and Zhidu greet His Royal Highness......" As soon as Liu De's carriage arrived, Zhidu came out with large and small subordinate officials to greet him.

Liu De stepped out of the carriage, helped Zhidu up with a smile and said, "Hurry up, calm down......"

For nobles and landlords, this goshawk is naturally a terrifying evil ghost and impermanence for life.

But for Liu De and his cheap father, this is a sharp dagger.

Basically, when you encounter a tricky problem, you immediately think: don't worry, I still have Zhidu!

And Liu De felt that Zhi was beaten into the legend of the cool officials, he was really wronged, compared to Ning Cheng, Yi Zong, Wang Wenshu and other descendants in the same legend of the cool officials, Zhi Du has never done anything to use power for personal gain and oppress the civilians, he has been fighting against the powerful and bullies all his life, and he has been fighting against the landlords and bullies in Jinan County while organizing the people to repair water conservancy, open up fertile land, and implement the policy of the imperial court to pay light and meager endowments, so that the population of Jinan has increased in the next ten years, which can be said to be a credit to the community.

Even Liu De later met some business travelers from Jinan in Hejian Country, and he could often hear the nostalgia of Jinan people for Zhidu.

"This time, there is Lao Qing's family......" Liu De smiled and took Zhidu's hand and said cordially.

"The minister doesn't dare to be His Royal Highness!" Zhi Du lowered his head and said.

"Qing is too modest...... Liu De shook his head, looked at Zhidu's calm face, and said with a smile: "I am relieved that Qing is in charge of this examination!" ”

Youzhi is here, and basically there is no need to worry about the order of the examination.

Liu De looked up at the rising sun, and said to Zhidu: "Qing is busy first, I still have something to do, so I won't talk to Qing more!" ”

He still has important things to do.

Saying goodbye to Zhidu, Liu De first went to Changle Palace, greeted Empress Dowager Dou, and gave her a set of eye exercises by the way.

Liu De naturally would not let go of this opportunity to get closer to the Empress Dowager Dou and cultivate feelings, during which he naturally tried his best to say good things and strive to win the feelings of the Empress Dowager Dou.

After such a routine, Liu De returned to his bedroom.

In the courtyard in front of the palace, a few mouthfuls of Dading were being cooked under the blazing fire, exuding a strong and pungent smell of medicine.

"How much has it been here?" Liu De walked over and asked Wang Dao.

"Back to Your Highness, I have boiled about more than a thousand catties and packed it in a wooden barrel, this is the second batch of boiled decoction!" Wang Dao replied respectfully: "Before the examination begins, the slave and maid can guarantee to boil out 3,000 catties of decoction for the scholars and the invigilators to drink!" ”

"That's good!" Liu De nodded, and a big stone in his heart finally landed.

Today's weather, compared to the previous days, I am afraid it will be hotter, to noon, the temperature can be said to be more than 35 degrees, in such a hot weather, if there is a large area of heat stroke, it will not be good for Liu De.

Fortunately, as a traverser, how could Liu De not know the herbal tea that was famous in the great foodie province in later generations?

Wang Laoji and Jia Duobao are two brands that are almost out of the dog's brain!

And the herbal tea recipe loved by the people of the big food province is also very simple, even if Liu De has never paid attention to it, he probably knows that there is honeysuckle and licorice in the herbal tea, and Liu De himself has made up two traditional Chinese medicines that clear heat and detoxify: chrysanthemum and prunella vulgaris.

In this way, a Western Han version of herbal tea came out.

Whether there is a gap or difference with the herbal tea of later generations, Liu De does not know, but at least with such a kind of tea to clear away heat and relieve heat, the accident of large-scale heat stroke can be minimized.

"Pour me a bowl and try it!" Liu De commanded.

It didn't take long for a bowl of herbal tea to be brought to Liu De, Liu De looked at it, the sales were poor, it looked like some medicines, not herbal tea for health care, pinched his nose and tasted it, and the taste was not very good.

"Put more licorice!" Liu De stopped eating after only one bite, poured out the bowl of herbal tea, and commanded.

That's all Liu De can do, if someone says that this herbal tea doesn't taste good and doesn't taste good, then he deserves heat stroke!

As for the fact that the scholar does not accept herbal tea and refuses to drink this kind of thing, Liu De is not worried at all, in fact, herbal tea can be said to be the oldest Chinese medicine preparation recorded in ancient China.

Liu De is not so much an invention as a resurrection of this traditional Chinese medicine soup to escape the heat and cool down.

"Are you busy, ......" Liu De waved his hand into the dormitory, picked up a piece of paper sealed in a bamboo tube from his couch, and took it out to look at it.

On this piece of paper, the five arithmetic questions recorded in today's exam.

Liu De looked at the last question on the paper and thought to himself: "Is there anyone who can answer it?" ”

It's a bit of a challenge!

This question is as follows: Eighty-one people answered the first question correctly, ninety-one answered the second question correctly, eighty-five answered the third question correctly, seventy-nine answered the fourth question correctly, and seventy-four answered the fifth question correctly. Those who answer three or more questions correctly are qualified, Q: How many people are qualified?

"Isn't it too frustrating?" Liu De thought in his heart and weighed it, this question, let alone the current people, is that many college students in later generations can't answer it, and Liu De didn't want to use this question at first.

But then I thought about it, what is the most fascinating thing about mathematics?

What an unsolved puzzle!

Without Goldbach's conjecture, Western mathematics would not have progressed so fast.

So as soon as he gritted his teeth, Liu De used this question that he was stumped by his nephew in his previous life.

It doesn't matter if no one answers correctly, and maybe even better if no one answers correctly!

The scholars are all embarrassed!

If no one can answer this question this time, it will undoubtedly be a strong stimulus for them, which can stimulate many people to study and interpret the mysteries of mathematics and find the laws of mathematics.
