In the sound of firecrackers, one year old, in the blink of an eye, it is the New Year, the new peach is replaced with the old charm, and it is five years of Zhenguan in the blink of an eye.

After Xiao Yun got married, the house became more and more deserted, Qin Hao asked all the servants in the family to beat gongs and drums, and all the sets were replaced with bright red, but he still couldn't feel the warmth of the spring breeze.

Perhaps, the family should be added too much.

Wei Zheng has said many times about having children, and every time the old man comes to Qin Hao's house, he always has to say a few words about the next generation, but whether it is Fluttershy or Li Xin, there is no movement in his stomach.

Qin Hao couldn't help but wonder in his heart, it is said that he has worked weekdays, and he has planted a lot of seeds, why can't he see the harvest?

Could it be that there is a problem with crossing?

In order to create a villain wholeheartedly, Qin Hao did not even hold a formal position, and now he only talks about advanced mathematics from time to time in the Ministry of Civil Affairs and the Tang Federal Reserve, and almost nothing else, even the operation of the Green Gang, except for the occasional concern about the construction of Xining City, is handed over to the Heavenly Rat.

For this reason, Li Xin tried to worship the Buddha and burn incense, whether it was Hongren or Yuan Tiangang, they were all frequent visitors to her visits, leaving a lot of incense money, but it was useless.

Qin Hao sometimes ate more leeks and oysters intentionally or unintentionally, but as a result, he was indeed much more fierce when he fought, but it seemed that the sowing was still the same as before.

Qin Hao would even be worried, how embarrassing it would be if Pei Xingjian's stinky boy grabbed in front of him.

After some clouds and rain, Qin Hao drank some wolfberry water, put on his clothes and planned to go out.

"Master, this is the New Year, even the yamen is on holiday, why do you still have something to do, so you can't stay at home for a while."

Qin Hao turned around and kissed Li Xin, and said with a wry smile: "I want to stay a little longer, the problem is that your father won't let me, I will go to the Tang Federal Reserve, after the Zhengyuan Festival, the deposit and loan business will be launched, the algorithm is a little more complicated, they still have to learn it, and I don't look at myself and I don't worry about it." ”

The Tang Federal Reserve was founded on the basis of the windfall profits made by the princes in real estate, with the Federal Reserve as the goal, and the payment of wages was just a small test for him, and deposits and loans were the main business.

Entered the Taiji Palace, came to the place where the lecture was held, the officials of the Tang Federal Reserve and the Ministry of Civil Affairs had already taken the banknotes and were waiting, and now Qin Hao's lecture was notoriously difficult in the Tang Dynasty, but it was also notoriously useful, even if he only learned one and a half moves, it was enough to be used endlessly in the future.

Therefore, Qin Hao's class not only had officials from the Ministry of Civil Affairs and the Tang Federal Reserve, but also many officials from the Ministry of Industry, Taixue, Dajiangjian and other places.

Passing through the early Tang Dynasty is such an advantage, Confucian culture has not been elevated to the point of almost mythology, arithmetic is still one of the most valued disciplines, but it saves him a lot of things, there is no need to bother to popularize the importance of mathematics, and the departments in need will come together by themselves.

Walking on the podium, Qin Hao lectured decently: "Thank you for taking a rare vacation to listen to the younger generation's class, today's course is mainly for the deposit and loan business launched by the Tang Federal Reserve after the Yuan Festival, so it is not so much an arithmetic course as an economic course." ”

"Deposits and loans, on the one hand, are the source of profit for the Tang Federal Reserve, laying a good foundation for printing money in the future, and on the other hand, it is also the mediation lever of my Datang national economy.

"To put it simply, when the money in the market is relatively scarce and the market vitality is insufficient, we should reduce the interest on deposits, raise the interest on loans, and make the money in the market active.

Then, Qin Hao explained in detail what inflation and deflation are, and lectured on basic economics for a whole class, which amazed everyone who listened to the class, especially Xiao Yu and Chen Shuda and others, who had ruled the country all their lives since the former Sui Dynasty, and today they realized that there are so many doorways here.

Everyone pondered that if these learnings could be popularized in the court, it would be much easier to govern the country in the future, at least more useful than poetry and songs.

There are even many people who are thinking about giving advice to the Holy Lord, adding economics courses to the clear arithmetic and increasing the proportion of arithmetic admissions.

In fact, Qin Hao is just a brick-thrower, he is not studying economic management, these things are just a scratch of the surface, he is only responsible for pointing out the road to these Tang Dynasty bigwigs, and the real economics still have to rely on their continuous improvement in future practice.

Of course, these bigwigs are old after all, and they can't keep up with the speed of receiving new things, what Qin Hao said can only understand at most two or three out of ten, but Li Tai, who has just returned from Yangzhou, is learning very fast, and even has the meaning of drawing inferences from one another, so that Qin Hao can't help but admire, it really deserves the name of intelligence.

After finishing the lecture in the evening, because it was the New Year, most of the officials went home for a reunion dinner, but Li Yuan politely entertained Qin Hao to have dinner in the palace, and asked him to bring Li Xin together, after all, he is now a relative of the emperor, although it is far-fetched, but it can barely make sense.

Qin Hao realized that there was something to say.

Although he didn't want to get involved in the family affairs of the Lao Li family, Qin Hao didn't seem to have any reason to refuse, so he had no choice but to agree.

After a while, Li Shimin and the eldest grandson Wuji brought Li Chengqian and Li Zhi over, for the New Year, their old Li family also had to have a family banquet, no matter what the relationship between the two of them was, Li Shimin still had to call Li Yuan's father at the family banquet, so it could only be Li Shimin who came to Li Yuan for dinner, birthday greetings, and sent blessings.

Well, Qin Hao had already imagined how uncomfortable he would be to eat this meal in a while.

Li Shimin was instinctively stunned when he saw Qin Hao here, although Qin Hao is now considered the humerus of the country, but at the family banquet, he even brought his own son only the one born by the eldest grandson, why did this goods sit here?

But today's home is Li Yuan's home field, since Li Yuan left him and wanted to come for his own purposes, Li Shimin didn't say anything, just smiled slightly and said hello to him, but Qin Hao still had to give people a gift like a thing, after all, is it the emperor.

"Second child, Qin Boy has been teaching for a whole day today, which is extremely useful for governing the country, do you know?"

"Yes, father, the minister has already told his son just now, and the son also plans to wait for the next year to let all the ministries and yamen send more people to listen to it."

Li Yuan said: "His set of things is the most useful to the Tang Federal Reserve, but we old men, to put it ugly, how much more can we live?" This new thing, I can't learn it, I asked him to stay today, just to discuss something with you. ”

"Father, you say."

"I want Qingque to enter the Tang Fed."
