For the time being, the cement test can not be done, the first-class clay, the second-class craftsmen, the imperial court transferred dozens of craftsmen to assist, this is necessary, not for Song Jiu's profit, but for the profit of the imperial court, the kind of rough cement at the beginning of the actual beginning in addition to Hezhou in use, also began to be sold to the outside world, making tens of thousands of dollars for the imperial court, and there are clear accounts in the three divisions. But in the past, these craftsmen had to build houses, even straw sheds, and it took a while. Without them, the test would still not work.

Song Jiu continued to wait for news, teaching while continuing other tests and supervising the construction of the opera house. In addition, there will be a big thing, that is, the root number table and the trigonometric function table, the density table, of course, people in this era may not pay attention to it, these will be compiled into a book, and there are various formulas for calculating the volume density pressure in the back of the book, which may be very important for this era, and all aspects are inseparable from measurement, including volumetric weight area.

If there is no such formula, it is estimated that this book will not be able to sell a single copy if it is compiled.

The most difficult thing in the middle is the trigonometric function, you can't get a degree angle with a ruler gauge, so you have to use the folding method, slowly correct it bit by bit, and forcibly make a degree angle, with a degree angle, you can use a ruler to draw a half-degree angle, a two-degree angle, a three-degree angle, and even all angles.

Then slowly measure the size of each side, divide with the abacus, the first one should be accurate in angle, the second should be measured accurately, not to a single digit, but four digits after the decimal point, this requirement makes the students hard.

That's it, it took a whole year.

The basic measurement is out, and the four digits after the decimal point are impossible to be exact, but it can be done to two decimal places without error, and it will be the third digit. Song Jiu didn't dare to pack tickets. But this is the world's first standard trigonometric table. With it, mathematics gradually systematized. It's not empirical, as it used to be.

It's coming out soon, and this is the last check.

Song Jiu was taking the students one by one at home. Count one by one, countless drawings, each with a large triangle on it. If it's not big, it can't be precise. At the very least, these triangles do not have an error of more than one degree of zero.

In fact, it is 005 degrees, which is also terrible, and the error of the angle will be greater.

Song Jiu drilled his head out of the vast drawings and kept rubbing his temples. The brothers and sisters of the Pan family walked in from outside, and Pan Weide was instructed by the Tian family. Pan Li'er sneaked out, stopped Pan Wei in the back, and dragged the students to the school to start practical classes together, not many students were in the school house, and the brother and sister came together. The Song family was relatively easy to enter, with the main gate, but there was no porter to guard the door, so they quickly slipped into the backyard, and Pan Li'er went to find Yuping. Pan Weide went upstairs to find Song Jiu.

Pan Weide beckoned to Song Jiu, Song Jiu came out, and Pan Liande pulled him into the living room below, where Yuping was making tea. Pan Weide said: "Jiulang, my mother asked me to ask you something. ”

"What's the matter?"

"Your house is not large, where is the dowry going?"

It cannot be said that the area is not large. The area is not small, although it is not as good as the Pan family. Ten large classrooms occupy it, which is a problem. When Song Jiu was thinking of a way, Yuping said: "That's it, there is an empty classroom in front, let them squeeze it and make room for the sundries in front, I will sleep in Shundian with Li's mother and Cui'er first, it's really not good, the inn's business is off-season during this time, there are many empty rooms, it is also under my control, and I don't break the rules by sleeping in it." Then twelve houses can be moved. ”

But it's not much, if the Pan family has a lot of dowry, the Tian family wants to save face, talk about pomp, turn simplicity into complexity, come to a thousand-person brigade, and twenty-two empty houses can't fit down.

Pan Weide said: "Jade lady, take me to take a look." ”

It must be seen, otherwise there is really no bottom in my heart, the two families are outrageous this time, Yuping got up and took Pan Weide to see the room. She has a good temper, is intelligent, and has a wide range of knowledge, and she taught herself accounting and arithmetic with Song Jiu, and the inn and Shundian let her manage it in an orderly manner, which makes many people in the government very respectful. If it weren't for the fact that the matter between the two of them had settled down earlier, some Yanai would have been able to really marry her back as a wife. And after consultation within the government, including the future opera house, it was also unanimously agreed to let Yuping manage it. It's really not easy for others to care.

When they left, Pan Li'er whispered, "Bad person, my mother is sad to death at home. ”

"Why?"

"She's worried about the dowry."

"What's so worrying about that...... suddenly Song Jiu laughed, I really hadn't thought about it before, Pan Mei wanted to do a big job, she wanted to be faced, one was to show the Zhang family, and the other was to show her colleagues, at least my chosen son-in-law was not bad. Song Jiu also came as he was told.

Fortunately, the Hezhou business and the glaze business were better than he imagined, and for this reason, Song Jiuyi expanded the glaze workshop again, and now there are more than 290 workers and craftsmen in it. Expansion is a good thing, you can make more money, but the expansion is fast, too hasty, not only are there many people, but there are more workshops one after another, more affairs, and all kinds of mistakes and omissions occur. This is Song Jiu's least favorite situation, and he did it precisely because of one word, money.

Song Jiuzhen didn't think about the Pan family, Pan Li'er reminded him, and Song Jiu thought of the Pan family's embarrassment. The Pan family can use nearly sixty percent of their dowry, and some can't use it to compensate for marriage. It's an exchange of courtesy. Also, the matchmaker doesn't count, those are all small money. Her family also has to hire people to carry it up, and all kinds of other manpower, which also cost money. and all kinds of waste. If the Pan family wants to be faced, the dowry is more luxurious than the dowry, and the Pan family will spend at least twenty or thirty thousand yuan.

Congratulatory gifts will solve part of the problem, but congratulatory gifts are gifts, not money, some can be turned into money, but once in and out, there will be a loss of several percent. Some can't turn out gifts, or make gifts worthless, such as some handicrafts, jewelry processing products, at least half of the loss of money and silk, are you willing to waste like this? The Pan family will not be short of money, but it may be very difficult to directly take out more than 10,000 yuan in cash.

"Don't laugh, the second brother spent a lot of money to get married in the spring, and the mother used a lot of money when she went south, and for the dowry, the mother forced out the savings in the hands of the eldest brother."

Song Jiu still smiled, laughed for a while and said, "If you want to blame your father, this money word makes me uncomfortable." ”

Tian hasn't reacted yet, Pan Li'er has already calculated a small account at home, don't think that Song Jiu is talking about fun. If you take out 50,000 yuan to study what kind of mud, the number of tables opened by the time will be large. Maybe there's going to be trouble.

Song Jiu saw her sad face, and said again, "Pity." Don't worry, I have a way to solve it for your family. ”

"My mother won't ask for your money, so what's going on?"

"It's not a ceremony, it's a courtesy, and there's a salute behind it."

That is the gift of money, goose cake, wine and tea, rich people add a few colored forging, there are not many gifts, one simple and two light. A few people lifted it and solved it. But there is one important thing, and that is money. The common people used silk as money, one or two silks, and later became one or two handkerchiefs. Those who have money are put in a box with silver, and an ingot of silver is put into it and carried to the woman's house. In fact, Song Jiu suspected that the Tian family really couldn't think of a good plan at home, and he was embarrassed to borrow it from others, who asked her husband to ask someone to hold a wedding like this. So he deliberately let out his breath in front of Pan Li'er and let Pan Li'er come to him.

Song Jiu said again: "That's it." I'll pick another auspicious day and send the gift in a few days. ”

"How's that going to work?"

"Don't worry, Li'er, it's May next year. I'm going to have a lot of money in my hands. That's a lot, enough to make you go from gold to sea pearl. ”

This pearl is a pearl, a pearl produced in the sea. Some grains are large and more expensive than jade. Often, some of the extra-large ones can reach thousands of dollars a piece. Pan Li'er lifted the little pink fist and hit Song Jiu. However, Song Jiu also rejected this way of marriage, which was too extravagant. Yes, I don't know how much silk will be used for a cement, but how meaningful will it be to study cement? A glass study also costs a lot of money, but how much money can Liuli make back? In addition, there are two types of acids that can be mass-produced and cost-effective. But this can't be said.

The fight didn't hurt, and in turn let Song Jiu take the opportunity to rub the oil a few times. Every time they meet, Song Jiu has to rub oil, and now the two of them are in a matter of course, as long as they don't touch the bottom line, Pan Li'er is also up to him. After a few moments, Pan Li'er's body softened and said, "No, there is still a month." ”

"What's the matter?" Song Jiule retracted his hand, Pan Weide was still looking at the house, he had to look carefully, how big it was, how many things could be placed, not piled up, the dowry came over, it was placed the same, and there was room to be left, so you must know it in your heart.

At this time, another guest came to the Song family, and as soon as Pan Li'er saw him, she immediately frowned, it was her uncle Wang Jixun.

Song Jiu also said coldly: "I've seen Wang Dalang, the distinguished guest has come to the door, what do you want to ask?" ”

"I'll show you something." Wang Jixun took out two things from his arms.

"Gems?" Pan Li'er asked strangely.

Song Jiu pinched her hand and motioned her not to speak, and then looked at Wang Jixun. Wang Jixun said: "Twenty thousand yuan." ”

"Uncle Guo, where are you robbing money?" Pan Weide saw him coming, and also walked over, just hearing this number, he couldn't help asking.

"Refuse to bargain," Wang Jixun took them into his arms again, ignoring Song Jiu's opinion, he poured a cup of tea from the teapot and sipped slowly.

Song Jiu sighed and said, "Wang Dalang, you are indeed robbing money. ”

The main store dishes are expensive, but there are expensive reasons, not to mention all kinds of extravagant tableware and various activities to enjoy, the dishes themselves are also expensive, such as fried vegetables, green vegetables must be selected from the best vegetables, and then only the cabbage heart, a green vegetable selected ingredients are less than one-twentieth of it, and then the soup, it is impossible to use water to make vegetable soup in the store, and use a variety of precious ingredients, such as ginseng, dried scallops and deer antler velvet matching, and then use bones and chickens to slowly boil out the soup sweat, and use them to make vegetable soup. Whether it's a gimmick or not, the taste is indeed delicious. Just like that chicken soup, sold for five dollars a bowl, it is really more than ten chickens are killed and cooked, after boiling the thick soup in a pressure cooker, and then boiling it over high heat to thicken, dense gauze to remove the oil juice on it, and even adding high-end goods such as deer antler and ginseng to it, not only the taste is delicious to the extreme, but it will also make up for people. That's why it sells for such a high price.

Shundian is a special case, the entire Song Dynasty, and even the Southern Tang Dynasty and Wu Yue are this one.

Other stores can't imitate it if they want to, without him, is there a location scenery, and architecture? There are grades inside and out, and the dishes can be sold at a high level.

But that's the case, if you meet a stingy person, go in and order cheap dishes, the two of you eat and drink well, and twenty or thirty dollars are enough, and by the way, you can enjoy it once. Of course, it's hard to say specifically those rare and precious ingredients such as bear's paws, dragons, and even tiger meat, and they are worth a lot of money without doing them. It's not that a pot of fried vegetables can be sold for hundreds of dollars.

And these ingredients are not used after they are taken, for example, after the chicken is boiled in soup, it will not be sold again, but will be eaten by the servants in the store, and they will be packed and taken home for their families to eat. Sometimes, in order to make a name for themselves, the servants deliberately take the guests to visit, where is the price, so the guests feel worth it after coming to eat.

This is a special case.

Then there is the price of jewelry, Song Jiu's glazed products came out, and the guests bought it back as jewelry, so big, it was only more than a thousand yuan. A male tiger skin is only worth ten yuan because of its good skin and rough black and beautiful flowers, a female tiger skin is only worth 1,000 or a few hundred dollars because of the thin flowers, a large crystal the size of a large water urn that is more beautiful than a real gem is only worth eight or nine thousand yuan, and a large and rare sea pearl with a length of more than an inch is only worth two or three thousand yuan. Usually, the high-grade sea pearl in the capital is five or six hundred yuan a catty, Song Jiu said that Pan Li'er is the price of sea pearls, and when converted into the weight of sea pearls, it is still the price of sea pearls.

The total weight of the two diamonds in the hands of Wang Jixun is only 100 carats, maybe a little more, but in this era, diamonds are not valuable, and occasionally appear in the African Tianzhu, and most of the small ones are thrown away, and only the big ones are picked out and sold as inferior gems. If it weren't for Song Jiu to use it, its price would not be as high as the price of high-grade red-blue-green gemstones. That is to say, the original price of these two diamonds will never exceed 100 yuan, and even in the southern market, it is only worth 20 or 30 yuan.

I don't know where Wang Jixun got it, seeing that Song Jiu wanted it, he didn't have much use for putting it in his hands, so it was better to slaughter Song Jiu. But he slaughtered too harshly, if he said that three or four thousand yuan was about the same, he opened his mouth to say 20,000 yuan, and he did not bargain.

However, Song Jiu really needed it.

Wang Jixun drank a cup of tea and said, "Jiulang, I don't care about the 20,000 yuan, but if you don't agree, I'll throw them into the water immediately, and you can send someone to fish them out slowly." ”

This neuropathy can really be done.

Song Jiu was silent for a long time, and finally spoke: "I agreed, but you give me five days to think about it." (To be continued......)
