Take Taobao to ancient times

A string of copper coins looks like a large amount, but in fact it is only two hundred Wen, but this is also the way the ancients used copper coins.

The copper coins are round on the outside and square on the inside, with a small hole in the middle, so even if you have more money on your body, you can string all the copper coins together with a string, and hang them on your waist to show off.

The most commonly heard is the Yiguan copper coin, which is a thousand copper coins, which add up to one tael of silver.

A string of two hundred coins is certainly not as much as usual, but it is eye-catching enough.

"Hey, that's a lot of money," the second aunt held the pile of copper coins like a treasure. Although she made a lot of money selling charcoal before, the money was never too much, "Do the math." , How much money did we make this time?"

"I made it..." The second uncle was confused for a while, and suddenly his eyes lit up, but he looked at Lu Siyu, "Xiaoyu, tell me, how much money did I make this time?"

"That's right, that's right, let Xiaoyu do the job for the money." The second aunt also set her eyes on Lu Siyu.

This question is very simple, Lu Siyu did a simple mental calculation, and quickly came up with the answer: "A total of 140 coins have been earned."

"That's a lot." The second aunt couldn't help but said, "It would be even better if I could do it for a long time."

"It won't be long. Although the tofu business is a daily food, most people still can't afford it. The most we can do is to make a little money before the Chinese New Year. After the Chinese New Year, we won't be able to make much money." Lu Siyu said truthfully. , This is also his embarrassment. The consumption power in ancient times is too low, and he can only go through it once and for all, unless when the living consumption power of Lujia Village and other surrounding villages can be improved.

Hearing about Lu Siyu's people, the eldest aunt, the second aunt, and the second uncle all looked a little regretful. A good business suddenly disappeared, and they felt somewhat unbalanced.

Lu Siyu looked at the faces of the three of them, and said with a smile: "Actually, it's not all bad things. At least the tofu business can last a few days longer than the charcoal business. If you can earn a little, it's worth it."

"That's the only way," the aunt nodded, and looked at the second uncle and the second aunt, "Don't be unhappy, we haven't been able to do these two businesses in previous years, and we are not happy that we have earned so much this year, and we are not happy." You can't be too greedy, can you?"

"Sister-in-law is right, we can't be too greedy," the second uncle said hastily, and handed over all the money in his hand to Lu Siyu, "Xiao Yu, the second uncle doesn't know how to count money, so you keep the money first, and when the elder brother comes back, put it in the Let’s count it together.”

Lu Siyu looked at the second uncle, with a smile on his face, nodded and said: "Okay."

When Lu Siyu allocated them before, he didn't make it clear whether they should be calculated separately or together, but if two people sell separately, and there is the rule of two pennies per catty, three pennies per catty, it is definitely impossible to sell them at exactly the same price. Now the second uncle Here, one catty of tofu is sold for [-] Wen, and the uncle's income must be less than or equal to his. In this case, he is willing to share it together. It can be seen that the second uncle really values ​​friendship.

Lu Siyu nodded, which can be regarded as fulfilling the friendship between the two families. Anyway, they have come here, and he has basically determined the temperament of the two families. With such a good partner, he will not easily let this relationship collapse.

The second uncle here sold out early because of his luck, but the uncle over there was not so lucky, and he didn't come back until evening.

At this time, Lu Youdi had already returned with an ox cart, and at the same time brought back Zhuang Jinhan who had been reporting for three consecutive days.

Regarding Zhuang Jinhan's appearance, Lu Siyu was already very calm. Regardless of whether the young master wanted to experience life or had other ideas, it had nothing to do with him anyway, and he was not at a loss this time.

"Why did you buy meat again at night?" Lu Siyu looked at the meat in Zhuang Jinhan's hand.

This time it's not pork ribs, but pork belly with even fat and thinness. The price of this piece of meat is much more expensive than ribs.

"Greedy." Zhuang Jinhan said.

Lu Siyu glanced at him: "Didn't you say yesterday that you like light food?"

"Hungry today." Zhuang Jinhan said without changing his face.

Lu Siyu had no choice but to take the meat in his hand. This person was much more careful than he imagined. Of course, this piece of meat appeared not because of his own greed, but for the consideration of Lu Siyu and the others.

"The ingredients at home are limited, so I can only stir-fry briefly, are you okay?" Lu Siyu asked.

"No problem, I'll eat whatever you do." Zhuang Jinhan said casually, still not paying attention to the issue of eating.

Not long after the two chatted, Uncle Lu came back with a load on his shoulders.

Lu Siyu looked over, and could see that Uncle Lu's burden seemed a bit heavy. Could it be that they were not sold out? If so, the amount of tofu tomorrow would probably have to be re-estimated.

Although Uncle Lu was carrying a heavy burden, his speed did not slow down at all, and he quickly walked to the door.

"It's just right, Xiaoyu, you are here, come and see what I picked back."

Hey, isn't it the unsold tofu?

Lu Siyu walked over, just as Uncle Lu opened the burden and took out the contents.

"Uncle, did you come back with soybeans?"

Uncle Lu had a smile on his face: "Some are traded, some are bought. Many people have soybeans in stock at home, but the quantity is not large, and they are too lazy to sell them in the town. I collected a lot after I left. Make an appointment to pick it up tomorrow.”

"Brother." Uncle Lu also came over, and was startled when he saw the soybeans in Uncle Lu's burden, "There are so many, brother, how did you become a soybean harvester?"

"Stinky boy, how do you talk?" Uncle Lu slapped Uncle Lu hard on the head. Although they both have sons and daughters now and are about to be grandparents, they are brothers after all. They were all good, so they started fighting straight away.

Lu Siyu smiled: "Uncle, how do you calculate the price of soybeans?"

Uncle Lu put his hips on his hips: "I pressed the price. A catty of soybeans is exchanged for a piece of tofu. If you sell it, it costs two cents per catty. Some people ask for tofu, and some people sell it for money, but the money I have with me today Not much, so we didn’t collect too many soybeans.”

Hearing Uncle Lu's words, Lu Siyu was a little amazed. He thought that Uncle Lu was very lucky, but he didn't expect Uncle Lu to be so bold. A catty of soybeans and a piece of tofu cost two cents, which sounds like the same price, but in fact Not so.

Just when Lu Siyu was amazed, Uncle Lu scratched his head: "Actually, what I don't want to suppress is that the algorithm of three renminbi and two renminbi tofu you mentioned earlier is a bit complicated, and I can't turn my head around, so I just use two renminbi." Regarding the pricing, I thought that no one would sell soybeans for two cents a catty, but I didn’t expect many people to sell them.”

Lu Siyu was a little dumbfounded, he thought that Uncle Lu suddenly had a business mind, but he didn't expect it to be such a reason.

But it's not surprising when you think about it. Although the price of two pennies is one penny lower than that in the town, the selling price in the town is already higher than the purchase price. The villagers really want to go to the town with their own soybeans If they were sold, they would definitely not be able to sell them at a high price of three pennies. Anyway, Uncle Lu took the initiative to deliver them to their door, so they were naturally willing to sell them.

"How many catties of soybeans are there in total?" Lu Siyu asked.

"I'm not very clear about this. I didn't bring a scale today, so I didn't do much calculations. I can only make a rough estimate, and there may be some more. Except for these soybeans, I only have ten cents left here." Lu The uncle took out the money on his body and handed it to Lu Siyu.

Lu Siyu took the money, and told Uncle Lu what he had said to Uncle Lu before, saying that the money returned from each transaction should be kept with him first, and then processed after calculation.

"This method is good. Your brain is smarter than ours, and you can calculate clearly. We can rest assured that you can do the calculation." Uncle Lu said firmly.

Lu Siyu was helpless, he had been told many times that he was smart during this time, if he hadn't had self-knowledge, he would even wonder if he had always underestimated himself, and he didn't even know when he became a genius.

After handing over the money to Lu Siyu, Uncle Lu went to get the scale, and finally weighed out that the weight of the soybeans was nearly one hundred catties. Obviously, the villagers gave more or less when they sold the soybeans.

"It seems that these ten coins are a net profit." Lu Siyu smiled. He currently has a total of 210 coins in his hand. After deducting the cost of today's two hundred catties of tofu of 120 coins, the profit is [-] coins. In addition, the one hundred catties of soybeans should be added.

"120 Wen, this is the investment in selling soybeans before, this time I will completely remove the investment, uncle, this time the money has to be collected." Lu Siyu smiled and handed the money to the uncle. The previous soybeans were What Lu Youdi bought back was the money from his uncle's family. Lu Siyu wanted to give it to him, but his uncle refused to accept it. He might as well take advantage of this time to pay it all together, and his uncle would not refuse again.

Sure enough, the uncle didn't say anything more, and just collected the money.

"I still have 44 coins in my hand. For the time being, the three families will not be divided. The uncle and the second uncle will each get [-] coins. It will be considered as an investment in buying soybeans. We will divide it when our profits have accumulated to a certain level. .” In order to avoid calculation errors, Lu Siyu simply gave the two an even number.

"That's good. I really don't have enough money today. With this money, I can buy more soybeans." The uncle said.

"But will it be okay for us to buy so many soybeans?" The second uncle hesitated.

"No," Lu Siyu knew what the second uncle was thinking, and interrupted directly, "Even if we can't consume it, we can still sell it to the town and county. As long as we sell all the soybeans before the next season's soybean harvest, we will definitely sell the soybeans worth two cents a catty. Can't lose."

In ancient times, there was no greenhouse technology. It is said that the plants in any season will come out in that season. Don't even think about out-of-season plants.

"Yes, that's the truth. As expected of a scholar, he is smart." The uncle praised again.

Lu Siyu was helpless again, and planned to shift positions: "Uncle, Uncle, it's almost time, let's go home first."

"Okay, then you all go back first and rest early." The uncle said with a smile, looking at him with a very warm gaze.

Lu Siyu silently wiped the sweat in his heart, turned and left.

Zhuang Jinhan followed Lu Siyu, and after walking for a while, he suddenly said, "You have a very strong calculation ability. It seems that no one I know can compare to you."

Lu Siyu: Have you been suspected?
