In the end, Wang Xuan saw that the two little guys learned so quickly, and after lunch, he taught them the unit of measurement after a thousand and the addition and subtraction within a hundred.

After teaching, Wang Xuan let them practice there by themselves, while he himself ran back to the East Chamber to see his daughter.

It's just that Wang Xuan hasn't played with Xiao Zimeng for a while, Li Fu ran to say that he had something to report, and Wang Xuan could only hand over Xiao Zimeng to Zheng Guanyin and deal with things by himself.

"Say it! What's going on again" Coming to the front yard hall, Wang Xuan saw Li Fu standing aside and waiting respectfully, so he asked.

"Back to the master, here's the thing, didn't the old man teach a group of servants the skills of roasting tea a few years ago, and arranged for them to fry a large number of tea, now the new tea in the fiefdom warehouse has piled up, plus the new tea from the tea garden outside Chang'an is also arriving in Chang'an one after another, the old slave just wants to ask the master, how to deal with these teas" Li Fu respectfully explained the ins and outs of the matter to Wang Xuan.

"Oh, there's already a lot of tea? That's a good feeling, this should be our palace to make a lot of money, in this way, Li Fu, you will go to the east and west cities today to set up a shop, and then according to the previous ministers of the court and the central government on the preference for tea eggs, as well as the quality of the tea, picking time, spring tea, or autumn tea, old tree tea or new tree tea, divide the tea into numbers, forget it, you don't understand this, you go to the plate shop first, and then find someone, pack all the tea and send it to me, and after I set the grade, I will hand it over to you to classify, and then sell" Wang Xuan heard Li Fu say that a lot of tea had been stored, and new tea from tea gardens from other places had also been sent, Wang Xuan was overjoyed and instructed Li Fu, but when Wang Xuan saw Li Fu's bewilderment, he didn't let Li Fu do it himself, but planned to do it himself, so he turned to Li Fu and instructed him.

"The old slave understands, the old slave will arrange it" After getting Wang Xuan's order, Li Fu also knew his shortcomings in this regard, and he didn't dare to take care of everything, so he hurriedly did what Wang Xuan ordered.

As soon as Li Fu left, Wang Xuan returned to the East Chamber, called Li Xin and the others who were sewing clothes there, and let Lianzhi look at Xiao Zimeng, while Wang Xuan took Li Xin, Zheng Guanyin and Yang Yun to start the formulation of the first tea grade in the Tang Dynasty.

Although in terms of drinking tea, whether it is in the past life or now, Wang Xuan does not necessarily understand much, but the simple old tree tea is better than the new tree tea, and the first spring tea is better than that produced at other times.

And because of the different varieties of tea trees, as well as the different origins, some teas, autumn tea is better than spring tea.

Even Wang Xuan's goods are not necessarily clear to later generations, such as the more famous black tea, green tea, etc.

But such a person was stunned and pulled his daughter-in-law to formulate a grading standard for tea there, which is really a bit ridiculous.

But there is something ridiculous like this, in the eyes of his daughter-in-law, it is so reasonable, just because the skill of roasting tea was passed down by Wang Xuan, and making tea also came from Wang Xuan, just because of this, Wang Xuan's tea grade grading standard may be a standard for tea merchants to buy tea and sell tea in the next few decades or even hundreds of years.

Of course, Wang Xuan himself doesn't know much about tea, but he knows how to set standards according to consumer preferences!

Otherwise, what do you think Wang Xuan asked Li Fu to use the records of those officials who came to ask for tea.

You must know that since he set up wine for Xiao Zimeng's birth and gave free tea to those officials, those officials knew that Wang Xuan had fried tea, so they often came to buy it.

And Wang Xuan of the chicken thief never gave them the same tea, every time someone came to buy fried tea, Wang Xuan asked Li Fu to take different tea leaves to these people.

After they drank it, they thought it was delicious, and when they came over again, they would ask if there was any tea from last time, and Wang Xuan didn't know that that kind of tea was more popular.

Therefore, if you don't understand it, it doesn't mean that you can't make standards well, as long as you find the right method, the result will be the same.

And that result was that the good tea that they had selected would eventually be sold to them by Wang Xuan at a high price.

I don't know if they will beat Wang Xuan to death together if they know such an inside story.

However, it is precisely because of this method that Wang Xuan's formulation of the tea grade grading standard was finally completed in less than two days.

With Wang Xuan's grading standard as a guide, soon the tea estates opened according to different groups of people in the east and west cities of Chang'an.

On the opening day, according to the report of the people arranged by Li Fu, it was really crowded, and even the tea sets in the furniture workshop were also booming.

It's just that within two days of the opening of the tea house, in Chang'an City, restaurants of various consumption grades have also opened ten in a row under the instruction of Wang Xuan, almost including Chang'an City, so the prosperous area.

And because these restaurants are aimed at people of different consumption grades, this opening instantly squeezed out nearly half of the market of the entire Chang'an restaurant industry.

This is still because Wang Xuan does not have enough funds in his hands, if the funds are enough, he can make the entire middle and high-end restaurant business in Chang'an surnamed Wang.

But this is the case, which also makes many businessmen who run restaurants miserable, when they used to be in a restaurant, they could still make a lot of money, but now that Wang Xuan is like this, their small life is not so good.

Now because there is no stir-fry technology, a large number of customers have been lost, and many people are already preparing to transfer the restaurant, so taking advantage of such an opportunity, coupled with the return of funds, Wang Xuan let Li Fu next nearly 20 restaurants, realizing the scale of a royal restaurant in almost a few large squares.

And to this extent, it only took less than two months.

Even after the large-scale restaurant industry in Chang'an became saturated, Wang Xuan instructed Li Fu to take Ruping and directly open a breakfast shop and braised meat shop in every square in Chang'an.

When these layouts were completed, Wang Xuan continued to expand the restaurant business, and at the same time cleaned up the restaurants in Chang'an City, which were not doing well.

As for why it was cleaned up, it was because the positioning of some restaurants was not good, or there was a conflict with the neighboring restaurants, so Wang Xuan wanted to clean it up.

But that's it, in just the past few months, Wang Xuan's restaurant, breakfast shop and braised meat shop have also brought countless jobs to the entire Chang'an, as well as a large amount of taxes, which made Li Shimin, as well as Changsun Wuji and others have an incredible expression on their faces when they get the news.

Especially Li Shimin, he was originally benefited by Wang Xuan's well-developed business, but now seeing such a result, it is even more impressed by Wang Xuan.
