In an extremely private room, Du Zi walked in front of Lin Sen with a thick account book in his hand.

This account book is quite detailed, every income and every expenditure are recorded in the book, one by one can be said to be no matter how small, the only bad point is that it is still used in the way of running accounts, and it is a bit troublesome to really take inventory.

Lin Sen simply asked the big shopkeeper to find some paper and pencils, so he did it himself, and according to the loan bookkeeping method, he did a double-entry bookkeeping again.

In this way, the relationship between income and expenditure can become much clearer, and it is convenient to know the income situation at the same time, but also to see the changes in a certain period of time, which is also a good way to kill multiple birds with one stone.

And Du Zikuan watched from the side, and couldn't help but feel a little scared in his heart, thanks to him not doing anything from it, otherwise under this new method, there would definitely be nothing to hide, so that the recognition he had worked hard for so many years would not be ruined.

In fact, this is also an important reason why Cheng Yanjin asked Lin Sen to come over to check the accounts by himself, since he knew that Lin Sen was involved in one of the roads, he happened to come from a restaurant.

can not only try his Lin Sen's quality, but also give his own shopkeeper Du Zikuan a wake-up call and supervision, after all, his own family sent someone to check the accounts, there is a feeling of distrusting his subordinates, I am afraid that it will cool the heart of the big shopkeeper, Lin Sen will not have such worries when he comes to do it.

And Du Zikuan was afraid, but he also had a little more expectations for this easy-to-use bookkeeping method, and the more he watched Lin Sen use it, the more he felt enlightened.

As for the Arabic numerals Lin Sen used, although he seemed to be a little struggling, he could easily figure out the correspondence between the numbers by comparing his account books, so he understood them very quickly.

And Lin Sen is quite satisfied with Du Zikuan's ability and loyalty, except for a few small mistakes and omissions in the entire account, which can be regarded as a careless miscalculation, the other accounts are very clear, and they seem to be more reasonable, not like a serious one.

"Has the price of raw materials increased recently? The cost of this piece is so much more. Lin Sen asked casually.

This is also the most obvious change in the ledger, the expenditure since the beginning of winter has increased significantly, and his eyes have actually been paying attention to Du Zikuan's performance.

"Isn't this winter, not only the price of vegetables has risen, but the price of meat has also risen a lot." Du Zikuan also sighed helplessly.

"But it's not these things that hate people the most, these things go up so much every year that everyone is used to it.

But in previous years, the price of lard did not rise so sharply, and it was not those bastards who actually learned from us to start stir-frying, although the taste was far worse than ours, but they also attracted some business.

There are more and more such bastards, and the oil in Chang'an City is not enough, so the price has risen so hard. If it weren't for the fact that we have a lot of pigs in Zhuangzi, the cost of this raw material would be even higher.

These are all bastards who should have their eyes off their eyes. Du Zikuan couldn't help but be a little indignant when he talked about this, it wasn't that he was jealous of the benefits brought by his own stir-frying, but they all came to follow suit, and they were simply robbing their own business.

"Fortunately, our stir-fry here has always been recognized as this," Du Zikuan gave a thumbs up proudly, "So there is never a shortage of guests, and later there is the hot pot that Lang Jun you made, we have made a lot of money this winter." Du Zikuan felt a little jubilant when he said this, and of course he praised Lin Sen a lot.

"Lard?" Lin Sen dragged his chin and said thoughtfully.

"I'll figure out how to go back and see." Lin Sen felt that it should be possible to find a replacement, but he still needed to test it well, and he never easily promised that he was not sure that he would be able to do it.

And if the method he thought of was successful, maybe he could open up an extra way for his own dealers.

"Then count on Lang Jun's magic method." Du Zikuan is full of confidence in Lin Sen, this master can always give him a lot of surprises.

"Uh...... Can this bookkeeping method used by Lang Jun be used? Du Zikuan asked with some apprehension.

"Of course, what's not to do." Lin Sen smiled and affirmed.

"Come, let me tell you in detail what numbers each symbol corresponds to." It's rare to meet a person who knows the goods, and he can be regarded as half of his own subordinates, and Lin Sen is not distressed at all when he teaches him such a method.

"But it's good for you to use this method yourself, and don't let outsiders learn it." Lin Sen thought that there was also a saying in the novel that this method was amazing, and it also had the effect of investigating corrupt officials and corrupt officials, and even stirring up the situation in the court, so he was afraid that it would be a lot of trouble, so he hurriedly told Du Zikuan.

Maybe you can consider offering this method when you go back, and then change some land to come back, it's really a shortage of land recently, and it's useless to hide it in your hands anyway.

After figuring out how much money he could share, he had a new idea, and by the way, he also got a strong hand with Ma Zhou, a cowman, and he was also full of wine and food, and Lin Sen could be regarded as having gained a lot, so he planned to simply go to say goodbye and go back to the Lin family Zhuangzi. The tulou over there was finally about to be completed, and he didn't want to miss the final inauguration celebration.

As for the money that belongs to him, naturally the Cheng family's guards will help send it to the Lin family's Zhuangzi, after all, there are so many, and it is unrealistic to expect him to want to transport it back with a leg.

waved his hand to signal that Du Zikuan didn't need to send it, and walked outside the hotel, but Lin Sen unexpectedly saw one of his few old people in Chang'an City, in fact, it was only a one-sided relationship, but the old beggar who impressed him very deeply.

This person who lives a bad life by himself, and can raise a lot of little beggars to grow up, is also a rare good person.

And Lin Sen met him twice, both when he made a lot of money, how to say it was also a good fate, so Lin Sen walked over again and put some copper coins into the bowl in front of the old beggar.

Lin Sen, who felt a little more comfortable, turned around and left very chicly, but he couldn't help but want to complain in his heart, this old beggar is really unprofessional, and he doesn't sell miserably, and he doesn't know how to shout "Pity me", he doesn't have any consciousness as a beggar.

If it weren't for the fact that there seems to be no shortage of kind-hearted people in Chang'an City, with this person's work attitude, I am afraid that I would not even be able to survive myself, let alone take care of those little beggars and raise them.

However, Lin Sen didn't see it, and when he turned around, the old beggar showed a rare smile, but immediately returned to his original cold, or indifferent, state.
