Although Lin Jin wanted to change the world on a whim at the beginning, if Wu Jiugong hadn't integrated the salt merchants and the Cao Gang, then she would have left this idea behind. But Wu Jiugong successfully held the salt merchant and the Cao Gang in her hands, and in the case of money and people, Lin Jin's previous idea had the possibility of being realized, so she naturally had to work hard for it.

On the road to achieving the goal, Lin Jin did not let go of the line of "cultural aggression" in addition to the benefits that could drive the chamber of commerce to work hard. She knew that mathematics was the foundation of most natural subjects, so she took out the mathematics in the library and spread it to the Chamber of Commerce.

In fact, in ancient times, in the early days, the status of mathematics was once as important as writing. During the Spring and Autumn Period and the Warring States Period, the Mohists and Confucianists, who mastered advanced mathematical knowledge and made things that were later regarded as "strange and obscene skills", were all momentarily learned; of the Western Han Dynasty

Zhang Cang of the Western Han Dynasty went from Long Liu Bang to Empress Lu, Emperor Wen, and Emperor Jing, from a small official to the prime minister of a country, because his mathematical knowledge crushed his peers, so he was named "Counting". From him, everyone saw the possibility of learning mathematics well and becoming an official, so his corrected "Nine Chapters of Arithmetic" became one of the classics that scholars must learn.

In fact, even if it was the Han Dynasty, using Dong Zhongshu to depose the hundred schools, respect Confucianism, and make the hundred schools wither, so that in later generations, the subset of the classics and the scriptures were the head, and the doctrines of the sons of the hundred schools were scattered and scattered, and the lost ones were lost, and they failed to get a good inheritance, but because mathematics is directly used in the national economy and people's livelihood, there has always been the cultivation of mathematical talents.

The Tang Dynasty's Guozijian had the setting of arithmetic, and its imperial examination system also had a special subject for mathematics, "Ming Arithmetic", but in the Song Dynasty, although the imperial examination system was greatly flourished, and "emphasizing literature and light on martial arts", but the subject of "Ming Calculation" was cut. Even if the household department and Qin Tianjian still need talents who are good at mathematics, but without a channel for promotion, under the influence of the "official standard" thinking, the people's attention to arithmetic has become lower and lower, from not paying attention to learning, to finally not learning at all.

Gradually, the vast majority of the literati in the country began to care less about mathematics. In their opinion, mathematics has nothing to do with them, and if they really want to calculate something, they can ask the staff. What they have to learn is how to seize the moral high ground to make their own reputation, and how to ensure that they will not be sunk in the ups and downs of the sea.

Merchants are the most pragmatic group in the world, and they know that poetry and poetry are of no use to them in business, but a good study of mathematics means good accounting, so they are very receptive to the math books that Lin Jin took out.

No way, with the expansion of the business territory, the chamber of commerce has an increasing demand for mathematical talents, but unfortunately, whether it is the country's national prison or the private school, whether it is large or small, the teaching is Confucian classics, and there are almost no teachers of mathematics.

Relying solely on the master to lead the apprentice, the mathematical talents taught in this way cannot meet the needs of the chamber of commerce, and in this era, the master takes the apprentice, because he is afraid that "the apprentice has been taught to starve to death to the master", so the master is very stingy when teaching the apprentice, as if squeezing toothpaste, it takes a long time, and when the apprentice learns the ability and can become a teacher, the cucumber dishes on the merchant's side are cold.

Therefore, the math book that Lin Jin took out was completely a relief to the Chamber of Commerce, and she couldn't imagine that she had other thoughts in it. Even if they perceive it, under the trend of profits, the thirst for mathematical talents makes them unable to take care of it.

In order to make the court and officials less exploit them, most salt merchants have been doing good deeds when cutting meat from them, when the butcher's knife is raised, so they have been doing good deeds, so many nursing homes, whether they are run by the state or private, have salt merchants behind them to give one or two. Therefore, these children in the nursing home have become a base for the Chamber of Commerce to cultivate reserve talents, and they have begun to receive mathematics education while reading and literacy.

In fact, according to the previous idea of the Chamber of Commerce to recruit talents, even if it is an apprentice, it is required that the background is clear and traceable, and it is not good for these children whose parents are unknown in the nursing home. But in this era, the idea of "official standard" is too strong, before the chamber of commerce cultivated children from normal families, after teaching them to read, many families felt that their children had qualifications and could fight for the imperial examination, and the private school opened by the chamber of commerce did not teach the classics of history used in the imperial examination, so they dropped out of school and transferred to other private schools that taught the imperial examination. In the end, the Chamber of Commerce had no choice but to accept the children in the nursing home.

……

After sending the newly copied seventh issue of mathematics and a copy of "Plane Geometry" to Wu Jiugong, Lin Jin chatted with him about Luzon and the Chamber of Commerce again, and went home.

Seeing Lin Jin, Yang Wan, who was buried in the accounts, hurriedly beckoned her to come closer, and pushed a stack of account books on the table in front of her, "Brother Jin, you came back just in time, hurry up and help me sort out these accounts." ”

Lin Jin smiled and sat down across from her and began to settle accounts.

Yang Wan took the gift list and began to prepare some affairs for gifts. She held a gift slip from the Jia family in her hand, shook her head and said, "I really don't know what to say." Although the eldest girl was sent to Jia's house, according to the time and itinerary, there should be no place at this time, right? However, the festival of the 'Ancestor Worship Festival' sent by the Jia family this year is also ......, "She really can't find a suitable word to describe the behavior of the Jia family."

Throwing the gift slip on the table, Yang Wan sighed: "Even if it's 'crossing the river and demolishing the bridge', it's not so fast, could it be that in the eyes of the Jia family, only the eldest girl is worthy of associating with them, and we are not worthy?" ”

The gift slip floated lightly to Aunt Lin, who was coaxing Yang Lin on the side, and she picked it up before Yang Lin reached for it, glanced at it, and showed an indescribable expression, and said: "This should be that the eldest girl went to his house anyway, so there is no need to be false with us." ”

Yang Wan sneered and said: "Hmph, just the Jia family's style, this virtue, the wife still wanted to marry the eldest girl back to her parents' family." Fortunately, the old man didn't agree, otherwise, he would have cheated the eldest girl for a lifetime. ”

Immediately remembered something and asked: "Mom, you said that the master promised to send the eldest girl to the Jia family, will it mean to marry the eldest girl back to her mother's family?" ”
