A man travels through time and becomes a widow, only wanting to pursue a career

I saw sketches of rattan baskets drawn on the paper, some of which were flip-top and could have a mirror embedded in them. There are also drawer-type ones, and the painter carefully painted the handles on the rattan basket.

I flipped through another page, which showed the size requirements for rattan baskets in each room. The size was marked next to each style. Liang Shiqiu looked at the calligraphy on the paper. The handwriting was ordinary, but the data was recorded row by row and column by column very neatly and clearly.

I flipped through another page and saw a triangular nest drawn on the paper, with a dog lying in the nest. The width and height of the triangle are labeled with some data respectively, and there is a line of small words next to the longest side, which looks like some kind of symbol.

Liang Shiqiu couldn't understand the string of symbols.

"Mrs. Chen, is this the record you made?" Liang Shiqiu asked while looking at it.

"Master, this is the record made by Mrs. Chen. The old slave and Mrs. Chen went to the inner courtyard to inquire about the needs of each room.

This is Ah Huang in the old lady's courtyard. The old lady said that the weather was getting hotter and she wanted to make a nest made of rattan baskets for Ah Huang. She only briefly stated her request. After Mrs. Chen asked her servants to measure Ah Huang's body size, I drew a nest like this. The old lady was satisfied with the style and said she would make it as Mrs. Chen drew. "

At that time, Shen's mother only saw Chen Changsheng's drawings and did not notice the numbers Chen Changsheng marked on the side of the triangle. She could not understand them and thought they were some kind of weaving technique for making rattan baskets.

Mother Shen said it simply, but Liang Shiqiu was a little surprised.

Liang Shiqiu knew the words 1, 2 and 6, but the that looked like a stick, the that looked like a chicken, and the that looked like Ah Huang's tail were all nothing.

Could it be words from the Western Regions?

Chen Changsheng quickly snatched the paper away, thinking that no one would find out.

Each room in the Liang family has different needs. Some want jewelry boxes, which are small in size. Some require cosmetic cases, which are slightly larger in size. Others have baskets for cloth and clothing, which are larger in size.

Each room has a different style and size. In order to record it conveniently and quickly, she could only draw a rough outline while recording it.

Mrs. Liang wanted to make a strong kennel, but Chen Changsheng could only think of a triangular kennel, because the triangle was the most stable, so he simply drew a structure for the old lady. Unexpectedly, the other party was quite satisfied.

She conveniently recorded some data again, but it was troublesome to write 1, 2, 3, 4, 5, so Chen Changsheng simply recorded it in Arabic numerals, and calculated the length of the hypotenuse of the kennel's triangle with a few clicks.

Thinking that there should be no Pythagorean theorem and Arabic numerals at this time, Chen Changsheng gradually regained his composure.

Liang Shiqiu was no longer calm, this... wasn't this the method in the Nine Chapters of Arithmetic.

Calculation is indispensable in doing business, but all calculations require the help of an abacus. Not many people know how to calculate an abacus. He also learned the abacus when he was young and traveled around, following some seniors.

Later, when I became rich and started to purchase land, I had to measure and calculate the paddy fields and dry land. When I encountered some irregular fields, the calculation was even more troublesome. Liang Shiqiu found many teachers and learned many methods before he understood it.

Unexpectedly, this seemingly ordinary and unremarkable country peasant woman in front of me could actually know the methods in the Nine Chapters of arithmetic.

What's even more frightening is that she doesn't even need an abacus and can calculate the data just by mental arithmetic.

Is it possible that Mrs. Chen is an expert who lives in the countryside?

Chen Changsheng really opened Liang Shiqiu's eyes.

Liang Shaoqin wanted to continue to act arrogantly, but Liang Shiqiu sternly stopped him, "You will make people laugh if you don't back down."

Liang Shaoqin's face turned red. His father had always doted on him, but today he treated him like this in front of outsiders. Liang Shaoqin didn't understand and left in shame and anger.

Chen Changsheng didn't want to expose herself too much, and she still had work to do at home. After she took the recording paper and put it away, she said goodbye to Liang Shiqiu and hurried out of Liang's house.

After leaving Liang's house, there was still some time before lunch. Chen Changsheng led Chen Erlu straight to the pork shop where he had been the day before. The butcher shop owner had a good memory and recognized Chen Changsheng and greeted him familiarly.

"Sister-in-law, should I buy pork or pig offal today? Lean pork is twenty cents per catty, and ribs are thirty cents per catty. The prices are the same as the day before. There are still thirty catties of pig offal, and the price is eight cents per catty. What do you want to buy, sister-in-law? ?”

Chen Changsheng remembered that the day before yesterday, he came to buy pig guinea pigs for only seven cents per catty, but today it had gone up to 8 cents. He couldn't help but ask, "Boss, you sold me pig guinea pigs for not more than eight cents the other day. What happened today?" Has it increased a lot?"

The butcher shop owner is also a down-to-earth person, and he said quickly, "If my sister-in-law comes here around the time, we can sell it to you cheaper."

"Why is this?"

"Sister-in-law may not know that I am not the only pork shop in Baishui County, and the prices are set by each shop. If I lower the price privately, I will be punished by the city secretary."

Chen Changsheng understood that the city department should be similar to the modern market supervision and administration bureau to prevent merchants from disrupting the market by raising prices randomly. It’s just that throughout the ages, there have always been policies from above and countermeasures from below.

"Then if I buy too much and need to be in a hurry, is there any other way?" Chen Changsheng asked tentatively.

The butcher shop owner understood the implication of Chen Changsheng's words, moved closer and lowered his voice, "If my sister-in-law wants more, I can ask my apprentice to deliver the things directly to the house, and the transaction can be done privately without letting others know."

Chen Changsheng understood, patted Chen Erlu on the shoulder and said to the butcher shop owner, "This is my son. If I am determined, I will let my son deliver the message."

After the conversation, Chen Changsheng bought a pound of ribs and two pounds of pig meat. Everyone had worked hard these days, so he took them back to cook a delicious meal for the children to satisfy their cravings. She asked for another ten pounds of fat meat, which she wanted to take back for refining.

Because there was a shortage of oil and water in ancient times, everyone would buy fat and thin ones. The thin ones were fried and eaten, and the fat ones were refined into oil. You can also eat the lard residue after refining the oil.

Chen Changsheng went to his usual noodle stall again. Today, the boss and his wife also took care of the stall together.

The noodle stall owner saw that Chen Changsheng, a regular customer, had come and received yesterday's errand fee. He was even more enthusiastic today, "Sister-in-law, I still want two bowls of plain noodles as usual, right?"

Chen Changsheng smiled and nodded, and the noodle stall owner quickly got to work kneading the dough. He also asked his mother-in-law to finish pouring the tea to relieve the heat of the two guests.

The noodles were ready in a short time. Chen Erlu only felt that there was more pickled cabbage in the noodles in his bowl. The boss smiled and said that he had made some new ones for the guests to try today.

Chen Changsheng guessed that it was because he had been patronizing the noodle stall in the past few days and paid the boss yesterday for running errands, so he bought more noodles and side dishes today.

She knew in her heart that this boss really knew how to do business, he was honest and smart. It's just that I plan to do the shopping by myself today, and I don't need a boss for the time being.

The noodle stall owner still smiled and said, "It doesn't matter, customers won't buy it every day, so don't worry about eating noodles." He also introduced the grain and oil store where he bought the last time to Chen Changsheng, who has been doing business in the city for many years. , it is clear which store is affordable and which store is not.

Chen Changsheng paid the fare and left.

Stir-frying ground vegetables every day consumes a lot of seasonings. Although the food gift package rewarded by the system is quite rich, Chen Changsheng decided to purchase it regularly. The shelf life of the system rewards is longer, so he should save those for critical times.

She counted the days, and she still had to wait three more days before the bracelet would give her a random gift package. She didn't know if it would be a food gift package. It would be nice to give her some oil, salt, sauce, and vinegar.

Chen Changsheng and Chen Erlu were divided into two groups. Erlu was not young anymore, so it was time to take on some responsibilities. Chen Changsheng took out half a tael of silver and asked Erlu to buy seasonings, while he went to buy other things. The two agreed to meet at the city gate an hour later.

She remembered that when she went to the village in her previous life, every household would raise some chickens, ducks, geese, pigs, cattle and sheep, firstly to sell them for money, and secondly for their own consumption. Now that the land in the front yard of my house is almost ready, I can buy some and keep it.

The pigs, cows and sheep are too big, and there is no room to build a shed for the time being. It is better to buy a few chickens and ducks, which can lay eggs and eat insects in the fields. Building a nest is not that troublesome, and the family has plenty of labor force.

Having decided like this, Chen Changsheng was looking for someone to sell chickens and ducks on the street. There happened to be a country man selling chickens and ducks with a dustpan on the roadside not far away. She stepped forward and asked in detail.

When the man saw the guests coming, he started shouting loudly, "We're selling chickens, we're selling ducks, local chickens and ducks, we'll keep you alive."
