One year passed by the sound of firecrackers, and it was the New Year again in a blink of an eye. The new peach was replaced with the old talisman, and the fifth year of Zhenguan was the blink of an eye.

After Xiaoyun got married, her family became more deserted. Qin Hao asked all the servants in the family to organize themselves, and all the sets were changed into bright red, but she still couldn't feel the warmth brought by the spring breeze.

Perhaps, it’s really worth adding someone to the family.

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

Qin Hao couldn't help but wonder. He usually worked hard and planted a lot of seeds, so why didn't he get any harvest?

Could it be that there is a problem with traveling through time?

In order to create villains wholeheartedly, Qin Hao did not even hold a formal position. Now he only talks about advanced mathematics from time to time in the Ministry of Civil Affairs and the Tang Federal Reserve. He almost ignored anything else. Even the operation of the Qing Gang, except for occasionally caring about the construction of Xining City, was left to Zhatianshi to be fully responsible.

For this reason, Li Xin tried to worship Buddha and burn incense. Whether it was Hongren or Yuan Tiangang, she was a regular visitor, leaving a lot of money for incense, but it was useless.

Sometimes Qin Hao would eat more leeks and oysters intentionally or unintentionally. As a result, he was indeed much more fierce when fighting, but he still seemed to be the same as before when sowing.

Qin Hao even felt worried. It would be so embarrassing if Pei Xingjian, that brat, grabbed him in front of him.

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

"Master, this is the New Year, and even the yamen is on holiday. Why do you have to work hard? 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 for a while. The problem is that your father won't let me go. I'll go to the Tang Federal Reserve. After the Zhengyuan Festival, I will launch deposit and loan business. The algorithm involves a little more complicated. They have to learn it. Besides, I don't feel at ease if I don't look at myself."

The Tang Fed was founded based on the huge profits that the princes made in real estate and aimed at the Federal Reserve. For him, wages were just a trivial test, and deposits and loans were the main business. Now the time has come, and it is time to test its quality.

After entering the Tai Chi Palace and coming to the lecture place, officials from the Tang Federal Reserve and the Ministry of Civil Affairs had already taken the banknotes and waited. Now Qin Hao's lecture was famous for the Tang Dynasty, but it was also famous for its usefulness. Even if only one move and half a gesture is learned, it will be enough to benefit endlessly in the future.

Therefore, Qin Hao's classroom not only included officials from the Ministry of Civil Affairs and the Tang Federal Reserve, but also from the Ministry of Works, the Imperial Academy, the Dajiangjian and other places.

The benefit of traveling through the early Tang Dynasty was that Confucian culture was not elevated to the point of being almost mythical. Mathematics is still one of the most valued disciplines, which saved him a lot of trouble. He did not have to worry about popularizing the importance of mathematics. The departments in need came by themselves.

Walking onto the podium, Qin Hao taught in a decent manner: "Thank you for taking the rare holiday to listen to the junior class show off. Today's course is mainly for the deposit and loan business launched by the Tang Federal Reserve after the Yuan Festival. Therefore, it is not so much a math course as an economics course."

"Disclaimers and loans are the source of profits of the Tang Federal Reserve, laying a solid foundation for future banknote printing, and on the other hand, it is also the mediation leverage of our Tang national economy. If we just aim for profit, the basic mathematical knowledge will be enough to support his business, but if we want to play leverage, we need a very advanced mathematics and economic foundation."

"Simply put, when the money on the market is scarce and the market is not active enough, we should lower deposit interest, raise loan interest, and make the money on the market active. When the amount of money on the market is too much and prices rise, we should increase deposit interest and loan interest to reduce the money on the market."

Then, Qin Hao explained in detail what inflation and deflation meant. He taught the basic economics of a whole class, which amazed everyone who attended the class, especially Xiao Yu, Chen Shuda and others. They had been governing the country for a lifetime in the Sui Dynasty, but today they realized that there were so many tricks here.

Everyone thought that if these knowledge could be popularized in the court, it would be much easier to govern the country in the future. At least it would be more useful than poetry and verses.

There are even many people who are thinking about giving advice to the emperor, taking economics courses in the clear calculation and increasing the admission rate for arithmetics.

In fact, Qin Hao is just a stolen bricks and a sensation. He is not a professional economic management. These things are just a superficial ones. He is only responsible for pointing out the way to the tycoons of the Tang Dynasty. The real economics still needs to be continuously improved through their future practice.

Of course, these big guys are old and cannot keep up with the level of receiving new things. Qin Hao can only understand at most two or three out of ten. On the contrary, Li Tai, who just returned from Yangzhou, learned very quickly and even learned from others. Qin Hao couldn't help but admire him. He really deserves his name as intelligence.

After the class was finished in the evening, because of the Chinese New Year, most officials went home for a reunion dinner. However, Li Yuan politely welcomed Qin Hao to have dinner in the palace and asked him to bring Li Xin along. After all, he is a royal relative now. Although it is far-fetched, he 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 Lao Li's family, Qin Hao seemed to have no reason to refuse, so he had no choice but to agree.

After a while, Li Shimin and Changsun Wuji came with Li Chengqian and Li Zhi. During the Chinese New Year, their Li family had to have a family dinner. No matter what the relationship between the two of them was, Li Shimin had to call Li Yuan’s father at the family dinner, so Li Shimin could only come to Li Yuan for dinner, pay birthday wishes, and send blessings.

Well, Qin Hao could have imagined how uncomfortable he would be for the meal in a while.

When Li Shimin saw Qin Hao here, he was instinctively stunned. Although Qin Hao is now considered the country's humerus, his family banquet was that he only brought the three of them born by Empress Changsun. Why did this guy sit here?

However, today's home is Li Yuan's home court. Since Li Yuan left him, he had his own intentions. Li Shimin didn't say anything. He just smiled and said hello to him. Instead, Qin Hao had to give him a gift like he was. After all, he was the emperor.

"Second, Mr. Qin has been teaching a whole day of class today. It is extremely useful for governing the country. Do you know?"

"Yes, father, a minister has already told his son just now, and his son plans to wait for the New Year to send more people to the various departments and yamen to listen to it."

Li Yuan said: "His stuff is most useful to the Federal Reserve Bank of Tang, but to put it bluntly, how big can we live? This new thing is not something I can learn. I asked him to stay today just to discuss something with you."

"Sir, you said, "

"I want Qingque to enter the Tang Federal Reserve."
