Shu An's eyes flickered, because Li Shimin came to the door again as he expected, and he had a lot of reservations last time.

It's just that last time Li Shimin was disturbed by a word, so he didn't get to the bottom of it.

Of course, even if he knew about Li Shimin, he would only make some observations at most, and it would not be so easy to prepare.

In fact, the easiest way is to mobilize a large amount of food, but unfortunately Li Shimin can't do it, and the manpower and material resources in this era are much slower than imagined.

And Li Shimin, who was sitting opposite Shu An, also had some emotion on his face, and now when he saw his own father, he felt more and more mysterious.

I can't see the slightest thought, even if it is above the prediction of the heavenly machine, even Li Shimin has some awe.

For the awe of ghosts and gods, of course, after Li Shimin's thoughts were flying, he had not forgotten the business of coming to the door today.

"The last time I talked to my father, the people of the world had a lot of doubts, and I asked my father to teach me."

Li Shimin said slowly, at this moment, he is not a high emperor, as if he is a tireless student.

Shu An nodded, Li Shimin's attitude was already very difficult, if it weren't for his identity and fame, presumably Li Shimin would not be like this.

Of course, there is another point that Li Shimin is not a destined emperor from birth, although he is not the founding emperor, but he is better.

"Yafu should know that this natural disaster in the customs has a wide impact."

"Although the people of the world also want to help the victims, the treasury is not able to sustain itself."

"However, the number of refugees in Chang'an is likely to exceed 100,000, so we can't see the refugees starving to death in Chang'an?"

......

Li Shimin's voice sounded slowly, with a hint of helplessness in his words.

Shu on the side listened to Li Shimin's words quietly, but there was some laughter in his heart, it was obvious that the emperor was moved by the original proposal.

With the help of these refugees, building a straight road to the steppe can not only facilitate the dispatch of troops to the Turks, but also strengthen the control of the steppe.

You must know that since ancient times, the grassland has always been a hidden danger in the Central Plains, the Xiongnu Xianbei in the Qin and Han dynasties, etc., the Wuhu Chaohua in the past, and the current Turks.

It was not until the rise of nomads later, in Shu An's view, that the alien races on the steppe in the Sui and Tang dynasties actually reached the weakest period.

Otherwise, there would be no such thing as the Heavenly Khan, so in Shu An's opinion, if he could control the entire grassland during this period.

If it becomes the ranch of the entire Datang, then it can be said that the merit is in the future, but it is very difficult to achieve this.

Shu An is just thinking about it, and Li Shimin has to do it himself, and he will provide a suggestion at most.

Although Li Shimin said so much, Shu An had already understood the meaning, that is, he was short of money.

It's not just that Shu An is short of money, even Li Shimin is also short of money, and it's not a little bit lacking.

Of course, in Shu An's view, Li Shimin is sitting on Baoshan and does not know how to develop it, after all, the potential of the entire Datang is more than that.

"I don't know what the people of the world think about the city tax?"

After thinking for a long time, Shu An's eyes flashed and he said softly, you must know that now the tax mainly comes from land, and the city tax is for the merchants.

But Shu An, who came through the country, will not forget that before he crossed over, the country's main tax revenue was a lot of sources of businessmen.

Of course, the status of merchants in this era was not high, and there were even some low, such as the rule that merchants could not participate in the imperial examination.

"City tax?"

Li Shimin's eyes flashed with a hint of doubt, and after a long time, he finally remembered what kind of tax this type was.

It's not just the tax of the vendors, but it seems that the city tax is not much, and it is less than a fraction of the other taxes every year.

Seeing the expression on Li Shimin's face, even Shu An couldn't help but smile slightly in his heart, presumably Li Shimin didn't know anything about this city tax.

It is not surprising to say, because this city tax, that is, the commercial tax, does not seem to be much at all, and it can even be said that there is only a little.

As for why this is the case, it is because I don't know how much this shop sells and how much profit it receives.

It is up to the individual to decide how much to pay taxes, and it is much easier to make false accounts than you think.

"Have Shimin seen the account book of the teahouse?"

Shu An was not in a hurry to speak out, with a hint of unhurriedness in his words.

Li Shimin nodded, his face was even more puzzled, he didn't understand what the relationship between this city tax and the teahouse was.

"So how much city tax do the people think the teahouse should pay, so how much should the whole world pay?"

Shu An's voice sounded slowly, and from Xiao Tui, Li Shimin must be able to see the clues.

At this time, Li Shimin also began to think, if there is nothing wrong, the teahouse should be a lot according to the city tax.

There are several teahouses in Chang'an, although the business is not as hot as Yafu's teahouse, there should be a lot.

In addition to the tea house, there are restaurants, other shops, etc., so how can the city tax be insignificant.

Li Shimin's face couldn't help but darken, this is considered dark under the lamp, even if he didn't expect that there would be such a situation in this city tax.

"No business, no treachery!"

In the end, Li Shimin couldn't help but say quietly, with a hint of anger in his words, but how to make these people pay taxes normally is also a problem.

After thinking about it, Li Shimin still has no clue, the whole world is so big, and the number of shops is unknown, and it is not so easy to verify the meaning.

"Follow Yang Jian's example."

"It's better to take Chang'an as a pilot and give these businessmen a deadline to make up the listing tax."

"If you don't make up for it, it doesn't matter, let the people report it, and if it is verified, the people can get one-tenth of the city tax."

Shu An's voice sounded slowly, it is unrealistic to rely on the supervision of the imperial court, and the best way is to let the people supervise.

In the past, in order to count the population, Yang Jian asked the people to report and was exempted from servitude, while Shu An directly gave money.

Once it is found that there are interests in this, then even if the court does not need to launch it, these people will go to help the court supervise it themselves.

You must know that before the crossing, there was still a professional anti-counterfeiting industry, which is similar to the supervision of municipal tax.

After the words fell, Li Shimin nodded, his eyes lit up slightly, and he seemed to think that this method was feasible.

On the other side, Shu An's eyes flickered, knowing that the city tax was not heavy in the early Tang Dynasty, and it could even be described as very light.

It's just that even so, under the investigation of Shu'an, there are still many businessmen who have learned to be greedy for these small gains.

It can be said that this has become a habitual thing, which is the so-called lack of people's hearts, not to mention giving a period of time to pay taxes first, which can be regarded as a buffer time.
