Spring came unconsciously, and in February, rapeseed bloomed outside Zhengzhou City.

It was still warm winter, and the winter wheat planting range was expanded to the north of the Changchun River, which could extend northward for hundreds of miles than the thickest winter wheat planting area in Zheng Lang's later generations. Rice also once reached the junction of Song and Liao, which was not the cold-resistant rice species introduced from Japan. However, rice planting in the north is most afraid of autumn cold. Rain is rain before white dew. Good thing, rain before white dew will make the rice fuller. Behind white dew is a ghost, one autumn rain and one cold, and the next rain will be cold. If it falls too much, it proves that the cold and hot air confronts faster, and the cold air will come down, especially on the harvest of northern rice.

Overall, the temperature in winter is still higher than in later generations in these decades. Kaifeng is the greenhouse effect in later generations. It is rare to not freeze in winter, but this era has happened many times.

The climate of Kaifeng has been warm winter in recent years. It will either be a little colder next winter, but it will quickly turn into a warm winter. You can see records of ice-free and snowless many times.

In February, the outskirts of Zhengzhou actually looked like Jiangnan.

The peach blossoms in early spring are blooming, the pear blossoms are blooming, and the rape flowers are yellow.

Not far away were a few casual guards. Zheng Lang had an incident. Although he was wearing casual clothes, he was wearing swords around his waist and looked around nervously.

Liang Huaiji followed the four children with a small yellow door, and shouted from time to time: "Run slowly, my little ancestor."

Li Gui and his third aunt giggled on the road.

But after a while, Baoshou started crying loudly.

She was the youngest and could barely walk or run. She didn't know anything. She applied some balm on her body. A bee didn't know it. She crawled along her cheek and stretched out her hand to pat it. It was slapped hard by it. Liang Huaiji quickly ordered another eunuch to go back to get the medicine and kept comforting Baoshou.

Zheng Lang, Zhao Niannu and Cui Xian also ran over.

Several children surrounded her nervously, and a small bag was swollen on their faces. Zheng Lang comforted: "Your Highness, you can't cry anymore, that little bee is pitiful. After it bites you, it will die soon."

Li Gui took his two little aunts and looked around and asked, "Duke Zheng, why did it die?"

"The bee's nail is connected to the internal organs and cannot be snatched out. But the bee will fly away after stinging, but the internal organs will be broken and can even fall off. It will die after just a short time of flying."

After saying this, Baoshou never cried again. He looked at Zheng Lang with his clear big eyes.

Qingshou asked, "Duke Zheng, why did it do that?"

"Because. They are very weak and sweet, they will attract the covetousness of many animals. Not only do they want to eat their honey, but they will also destroy their hives. So we need this poisonous nail to defend their homes." The three little princesses in the name are Zhao Zhen's daughters. In fact, Zheng Lang also treats them as his daughters and teaches them, but because of Zhao Niannu, the relationship is a little messy.

"Mr. Zheng, I have to defend a few aunts when I grow up."

"How did this child say?" Zhao Niannu hit his son hard on his head, which was so unlucky.

"I'll go find it and bury it," Baoshou said, covering his swollen face.

"Okay. Look for it slowly." Zheng Lang said.

"The medicine has not been applied yet," Cui Xian said.

"Don't be afraid, bee venom is also beneficial. If you let it bite it appropriately, you will not get asthma, rheumatism and other diseases. Of course, you should not let it bite too much. If it is toxic, people will be dangerous." Zheng Lang said lightly.

Hearing that it was okay, Zhao Niannu let the children go away again, looked at their backs, and said, "I feel very relieved when I see them growing up."

Worry, Gao Taotao raised eight children for Zhao Shu, the second son and the youngest daughter were born early, and the other six grew up safely, but Zhao Zhen's child survival rate was less than 20%.

"They will grow up safely," said Zheng Lang.

Zhao Niannu was afraid that he would be sad, so he could only smile when he spoke, and Zheng Lang was also afraid that she would be sad, and he also smiled gently when he spoke.

Cui Xian looked at them with a speechless heart. In fact, he could see some of the figures of the late emperor from Zhao Niannu, but he just didn't mind. Can he take Zhao Niannu into the Zheng family?

The people in the distance also looked at several people.

It’s not just to be curious, that’s a kind of sadness.

The sadness is getting stronger and stronger.

It is because of the country's finances.

Whether Han Qi and Ouyang Xiu are good at managing or not, they are not meant to be harsh on the people. The national finances have left dark holes, causing a series of major events. However, historical books do not hate them. This is why, coupled with their articles and the tampering of gentlemen in later generations, they rarely see the connection between Wang Anshi and Han Ouyang.

But now the Song Dynasty is definitely different from the Song Dynasty in history.

First, it is about deficits. Two words often appeared in the Ming and Song dynasties, to repay the world's debts, or to sack (removal) the world's debts. Two types of debts mean two. The latter means that households below the fifth grade pay taxes. If they pay internal governance, they cannot be locked in a cell and beaten to death because of taxes, so they owe it year by year. In the case of economic improvement, they moderately lose these debts and give the poor people a chance. However, some officials want political achievements and will do some bad things, and they will capture people to force their families to sell houses, land or repay the benefits with high loans. Bao Zheng once stopped the officials from arresting them, which was to stop such behavior.

The former is because the court cannot turn over the fiscal turnover, especially in the Ming Dynasty, where there is no provident fund or bank funds to be misappropriated, but the country must operate. Therefore, it borrows from wealthy households, but cannot continue to borrow, and repays it when the finances improve. Or demolish the east wall and repairs the west wall to repay, maintaining the operation of the country.

This borrowing is just borrowing from some wealthy families without power, but the real powerful families dare not move. If they move, there will be a high price.

Even if you repay, you may not be able to repay it.

Therefore, Zheng Lang did not think that capitalism could emerge now. The official-oriented thinking was too serious. Even without borrowing, he could use the imperfect tax system and laws to destroy some wealthy families who were powerless and powerless. Then there was a series of farces that occurred below the list. Some wealthy families captured some old Jinshi with white hair, not only paid for money to marry their daughters, but also married a yellow-flowered daughter who was as beautiful as a flower. There was no way, and they were involved in officials and powerful people. The capital they had was very unsafe and they collapsed.

Under the joint management of Zhao Zhen and Zheng Lang, the reputation of the Song Dynasty improved.

However, some bad things happened. The two of them had the same virtue and were too soft-hearted to the people. For example, the Yellow River River was just digging. Zheng Lang was so annoyed that he sent officials to persuade them to compensate. The people were treated preferentially and got used to it.

In the past, rich families in the Song Dynasty had nowhere to go to capital, so they had to pay interest and deposit insurance money in the cash counter. They either used usury loans, but there were not many good people in this industry, and not all wealthy families were willing to use the remaining money to provide usury loans.

The emergence of banks gave these capitals a place to go and could still obtain interest. Although the interest was not very high, there was interest. Before the bank came out, even if the court had to pay ten or twenty years, everyone did not care. Moreover, the economy of the Song Dynasty was much better than that of the Ming Dynasty. It would have to be returned one day. However, the emergence of banks, officials from all over the country wanted to ensure the operation of the country and borrowed money from wealthy households without paying interest. This would cause many complaints.

The powerful and powerful families dare not move, so they can only transfer to ordinary wealthy families, or even eventually transfer to the people. Last year, Sima Guang had already written a letter to mention this matter, and the country still found ways to operate it, and borrowing would cause a lot of turmoil.

But what should Han Qi do if he doesn't use this method?

Either the people were fishing and didn't want to. Or they used the bank's money and Yan Rong watched it tightly. But looking at the expenses last year, the money from Shanling was blocked by the bank, but it cost nearly two thousand yuan to reward soldiers alone. There were also rewards from foreign relatives of officials and powerful clans, as well as the additional expenses brought by promotion. This was a huge sum of money.

The bank did owed a large amount of money, and Ouyang Xiu hurriedly took over without making any big mistakes, but because of waste, he also generated an additional amount of millions of yuan in debt. Once, the bank owed a huge debt of 95 million yuan. Could it be that it would not be repaid?

Therefore, we took the old path and asked officials to borrow money from wealthy families, but borrowing at this time is different from borrowing at that time.

They don’t want to be harsh on the people. They even relax their taxes, but if they continue to promote them, the pressure will eventually be spread to the common people.

It is not serious at the moment, and the people cannot see this change. They just feel that the late emperor has just died for half a year, and it seems that all aspects are not as good as before.

This four-sized family is all the descendants of the late emperor. Therefore, when they look at them, the common people's eyes are full of sympathy and a different kind of sadness.

Zheng Lang doesn't think so, and Cui Xian doesn't think so.

The husband regressed, and many ministers believed that his husband was weak. In reality, there were three ways to fight. The first was the lowest, like Fan Zhongyan, Kong Daofu, slapped the palace gate, and even kidnapped the teenage Zheng Lang. Although this kind of fight seemed hard, the actual success rate was often low, it would also arouse hatred. The second fight was to use interests to induce and force, such as Gao Taotao treated Zheng Lang with preferential treatment, rewarded officials and titles, promised to let Li Gui's son's surname be Zheng in the future, and that

The prince's tutor is the most expensive, but it is sent to the fire pit. The prince's tutor is not very serious. He is full of sincerity and forces his husband to compromise. Zheng Lang's balance of interests between various parties when he was the prime minister in the Secretariat. This is also the category. The third type is a higher struggle, such as the "rule by inaction" in the late emperor's rule, such as the husband's transfer of his own, such as Ju Jian's sleeping on firewood and tasting gall. The former is a kind of clever regulation, the latter is a kind of clever grasp of advance and retreat, and both are available.

He neither became enemies with the royal family nor rescued Zhao Zhen and his daughters from the fire pit.

What can I have in the palace? A noble golden-wire bird locked in a cage. When the late emperor died, there was nothing except the gorgeous palace. Although he lived in Jining Temple after leaving the palace, his residence was not as noble as before, and there was no shortage of other things. Do you dare not give it to the servants, eunuchs, palace maids, Zhao Shu? But he will not be discriminated against by the harem because of Zhao Shu's suppression. There is still freedom...

"Let's go to the workshop to have a look." Zheng Lang said.

Zheng Lang said it was just daily necessities, it didn't matter, but it was not.

This will be another huge Thomas. Zheng Lang originally wanted to hand it over to the court. Zhao Zhen passed away and felt sad and uncomfortable. He felt guilty and changed his mind.

That's soap.

Before soap appeared, detergent products appeared very early in ancient times. The main ingredients were sodium carbonate and potassium carbonate. The former was a lake mineral product, and the latter was a washing ingredient mainly composed of wood ash. Western inspiration was that a Mediterranean chef accidentally knocked over the oil on the wood ash and found that it was very useful for washing hands. This was the earliest record of Western soap. Later, the original soap appeared, and the effect was not good. In the seventeenth century, a chemist improved the original soap. It made a little progress, and then until Shevre invented the alkalization of butter, which took an important step in industrializing soap.

China is heading for another path, pounding animal fat and alkali, drying for a few days to use it to wash things, called pancreatic sap. In fact, these days are a chemical reaction process. Some people use clean water to soak wood ash, and the remaining substances after filtering can also be used to wash things. Or soap beans. As for bathing, there is no bath, scrub the skin with water and wood chips, and moisturize it with oil. The Zheng family also uses this method to bathe.

This is acceptable. However, Zheng Lang could not accept brushing his teeth with a ponytail, so the Song Dynasty invented a toothbrush.

It can produce better soap, but it is still the original one, and Zheng Lang did not expect it. It was not until the method of making glycerin that Zheng Lang had an idea.

If you want to produce more yellow* in large quantities, you must industrialize it. Glycerin is indispensable in the middle. Zheng Lang changed another direction. He cooked caustic soda and oil. After this chemical reaction, two substances will be produced after hydrolysis, one is high-fatty acid fat and the other is glycerin.

Alkali was widely used for a long time, but not soda ash. It was extracted from natural alkali to soda ash, and then from soda ash to caustic soda, which seemed to be all alkalis, with completely different chemical compositions. After several years, it was mainly because there were fewer people developing them. Once more, these substances appeared one by one, and a chemical era would eventually come. The industrial foundation was too backward and still very far away, but if you go step by step like this, it might take less than two hundred years to advance the Song Dynasty into the 18th and 19th century.

It is for glycerol, but the former's high-grade fatty acid fat finally made Zheng Lang think of soap. In fact, if we can produce nearly a hundred chemical substances from the laboratory regardless of cost, it is not easy to industrialize and popularize them.

It was a long time before Shi Heng wrote to Zheng Lang until last spring that the production cost had really dropped. Zheng Lang thought of using it to make soap. Of course, it could make another thing, detergent. However, if it was used to make detergent, it was probably only Fanlou and a very small number of nobles who were noble. It was better to add a little spice to turn it into soap and commercialize it.

Zheng Lang doesn't know much about how much benefit it will produce.

The workshop is located in Zhengzhou. First, he doesn’t want to attract many people’s attention. Second, there are many people in the capital. His unclear relationship with Zhao Niannu will lead to gossip when he gets too close. Third, he is in Dingyou and will stay in Zhengzhou in recent years.

The workshop was built very quickly. I heard that it was built by the late emperor and a few princesses. Many people came spontaneously and didn't want to pay them wages. Some even cried while building them.

However, it will take a series of assembly and experiments for the official launch. The soap was not really released until March. Spices and exquisite packaging. Some high-end soaps with precious spices are not only exquisitely packaged, but also some boxes with gold and silver silk wrapped in silk. The lower ones are also priced at fifty cents, and the higher ones can reach a scoop. This is the initial price. Once glycerin can be used universally, the efficiency will be improved, and the cost will be further reduced, the price will be reduced step by step and popularized to the public.

And soap is the beginning.

In order to improve its sales and to dispel some people's unintentional intentions, Zheng Lang engraved three big characters with a mold, the emperor's heart.

This is a product made for the daughters of the late emperor, so don’t make any idea.

Of course, it is not within the scope of taxation.

The sales time and location were published in the newspaper in advance, and the first batch was selected for several major stores in Beijing during the Qingming Festival.

As a result, on the Qingming Festival, countless people came to me. I couldn't bear to spend a lot of money on daily necessities, but ordinary people could still afford it. Many people actually bought it but didn't know its function. They just wanted a few princesses to live a better life and blindly lined up to buy it.

Qingming Festival is another sentimental festival. Some people line up while burning paper lines and sobbing in a low voice.

The people who bought it finally discovered its magical use, and even used it to wash clothes. There was no incense on the clothes, but there was a natural and unique fragrance. Some people wrote an article to praise it. But not many people paid attention to it. They only noticed that after half a year, the people continued to think about the late emperor. Although the posthumous title of the court was benevolence, it might have made the people think about it for so long, and not mention martial arts, but just this kind of benevolent policy can be said to be unprecedented. They wrote articles or wrote poems to praise this matter.

Finally it was spread to the temple, and Zhang Gui wrote a letter in a vague way. Everyone agreed that the two nobles became monks and Taoists, took the three little princesses to pray for the late emperor, and even agreed that the eldest princess brought the three little princesses to Zhengzhou. The two nobles did not dare to go to Zhengzhou.

I don’t know the truth about Zhao Niannu, and I am the owner of Jining Temple and the real owner of the workshop. I have to go there. If two noble people go there, they are not as big as Zhao Niannu, and they are a bit like a little bit like a plum tree. This is the one who has no one to gossip about, Zhang Gui is talking about the sign of the emperor’s heart.

If you touch the word "Emperor", how can you let it bathe and remove dirt for the people?

Zhao Shu rarely said one word: "Accurate."

Sima Guang stood up and said, "Your Majesty, I think Zhang Qing's words are inappropriate. Why is it to take a bath to remove dirt? This is to bathe. What is the virtue of a man? Bathing in the world, spring is to revive all things. It can bring spring-like bathing to all the people. This is what the benevolent lord does. The late emperor was in power and ruled without doing anything, only remembering a little bit. Love the people. The emperor's heart is used to bathe the people, so why not do it? When Your Majesty was the emperor's heir, the people praised Your Majesty and hoped to return. If as Zhang Qing said, the emperor's heart could not be used to bathe, would you let Your Majesty be kind to the people? Please think twice."

Oppose it but more of it is fooling people, and Zhao Shu can no longer speak out. The ministers also stood up and agreed, at least in the Song Dynasty, Sima Guang's theory made sense.

This matter has been revealed and no one dares to mention it again.
