The delicacy of sweet potatoes made everyone have a great confidence in the sales of sweet potatoes, Cui Yingying began to plan the sale of sweet potatoes, Shangguan Yi and other officials also cooperated with the establishment of the exhibition, the businessmen in Yizhou keenly smelled a trace of unusualness, and began to listen to the news, and soon the new sweet potatoes were eaten, and these businessmen immediately took action to allocate funds.

Since the opening of the Tang Dynasty Bank, and the Tang Chamber of Commerce has preferential policies for merchants who use money tickets, the merchants of Datang have deposited copper coins and gold in various states, exchanged them for money tickets, and then took them out in Yizhou, or directly traded with money tickets.

Because in addition to the money ticket used to save money, the Tang Dynasty has a special money ticket, this kind of money ticket is called cash by the Tang Dynasty Chamber of Commerce, which is a kind of money ticket that Li Su can directly use as a commodity transaction after saving money tickets, different from savings money tickets, this kind of money tickets can be exchanged for huàn copper coins by anyone who gets the Tang Dynasty money bank, which is very convenient, although it is conducive to large-scale transactions, but at the same time, you have to bear the risk of losing this money ticket.

But even so, there are still many businessmen who are willing to exchange huàn money tickets, because it is really very convenient, but this kind of transaction is only popular among businessmen at present, and the people still do not agree with money tickets, which is also expected by Li Su, this kind of thing can only be done slowly.

Li Suxing's money ticket is just to promote commercial exhibitions, behind each money ticket is real money, one to one, he will not print this kind of banknote, at least he still has a conscience.

Tong Yu's drilling rig team arrived in Yizhou City the day after Li Su's return to Yizhou, and Li Su asked them to first go to the government affairs college, the military academy and the medical school to drill wells, and finally to dig wells here in the palace.

Taking advantage of this time, Li Su returned to Hyundai and purchased a hundred digital cameras and thirty color photo printers, and the matter of this pass could not be delayed. In the future, not only the research institute, but all industries of Li Su will implement the pass and identity card system, one is to enhance management, and the other is to avoid some fine work mixed into various industries.

Moreover, Li Su was preparing to conduct a census, the household registration system in the Tang Dynasty was relaxed, and the census was only to households. It is not clear how many people are in each household, the population of Chengdu Prefecture is 1.7 million on the surface, but in fact, it is only an estimate of the number of households, and there are still so many black households in modern society, not to mention the Tang Dynasty, after the census, Li Su will be transformed into the household registration system of the capital. Learning about contemporary hukou management and printing ID cards will be beneficial to all walks of life and will also benefit the overall management.

To this end, Li Su specially summoned Shangguanyi and other officials, studied the experience of modern household registration management with them, and asked them to carry out the census and household registration reform in the following time. As for the printing of the ID card, the Shengtang Chamber of Commerce will be responsible for it, and after the household registration is counted, it will be issued to everyone who has a household registration.

"Nowadays, the household registration of Datang is only counted to each household, and how many people are in each household is not very clear, and when you conduct a census next, you must check how many people in each household are clear, which is very important for the future division of land and taxation. Don't be sloppy. Li Su said sharply, he can joke about it on weekdays, but in the face of business, Li Su is absolutely meticulous.

Everyone nodded, and Dou Xiande said, "Your Highness, how do you count the slaves and maids?" ”

"The slaves and maids are also counted, and they are still recorded as slaves." Li Su did not intend to abolish the slave system.

The basic things have been explained clearly. After the meeting, Li sent people to transport digital cameras and printers to Taoyuan, where he stayed for a few days to train twenty slaves and maids, and then let them start making Zuò passes and identity cards.

"Raise your head a little higher. Don't squint, go a little to the left. ”

In front of a blue square cloth, Qin Huaiyu was listening to Li Su's command and constantly adjusting his posture, Li Su was holding a camera in his hand, and there were many people around him, all of whom were people who came to apply for passes and identity cards.

"That's it!" Pressing the shutter, Li Su shouted.

This room is specially used for taking photos and printing photos, and today Li Su was just about to go back when he was hit by Qin Huaiyu, and when he learned that Li Su was here to apply for a pass, he had to pull Li Su to get him one.

Printing out the photo, Li Su pasted Qin Huaiyu's portrait on a palm-sized hard card, and then wrote Qin Huaiyu's name, position, and function below, and then took a plastic sleeve and sealed it with a plastic laminator and handed it to him.

Qin Huaiyu was watching the whole time, as if he had seen a ghost, took the identity card, Qin Huaiyu looked at the avatar for a long time, and said with emotion: "Your Highness, what is this?" It's exactly the same as me. ”

When he said this, the people in the research institute laughed, they had long understood the principle of the camera, so it was not surprising.

Li Su ignored him and said to Tong Yu: "All the people who enter and leave Taoyuan will give them an identity card in this way, and they will apply for additional passes when they enter and exit some important places." ”

"Yes, Your Highness." Although he has learned the principle of the camera, it is the first time he has seen this kind of camera, and his psychology is still very shocking.

Qin Huaiyu interjected: "There are also those from our military camp." ”

"Yours are indispensable." Li Su stood up and planned to go back, and asked him, "Are you going back?" ”

"No, I'm going to play soccer in the afternoon." Qin Huaiyu said with a smile, with these five thousand people, he doesn't have to worry about no one playing.

In addition to the matter of the identity card, Li Su said to Tong Yu: "Also, you let the drilling rig team go to the Shengtang Chamber of Commerce to report to your father, and the matter of Yanjing should also start." ”

"Okay, I'll let them go in the afternoon." Tong Nian also came to Taoyuan to urge him a few times, and now that his son has a chance, Tong Nian is also very happy, but when work is work, he still scolded Tong Yu.

This Sichuan is a large province of well salt, and this Zigong is the main well salt production area in Sichuan, almost everywhere is well salt mines, but at this time this area is not well known, Tong Nian sent people to see, there is still a wasteland, there are no residents, it is a good time to open up, he believes that as long as the salt well is drilled, there will be a rapid development, and the cement main road in Yizhou will also extend there, but this is not a short time to do, after all, road repair is also a long-term project.

When Li Su returned to the palace, the pressurized water wells in the palace had been installed, and a total of three were built, two in the north courtyard and one in the south courtyard, which was enough for the palace.

The families gathered around the pressurized water well, Rongda was pumping water in a good way, and the people around were all praising it, this pressurized water well was not known to be many times stronger than the normal well.

"Rongda, where is the man who digs the well?" Li Su got off the horse road.

Rong Da, who was concentrating on drawing water, immediately squeezed out of the crowd when he heard this, "The person who dug the well was called by the princess to the new palace in the south."

Li Su nodded, since the construction of the new palace, Cui Yingying is very sad about the construction of the new palace, this palace is only 3,000 square meters, Cui Yingying has always disliked being too small, according to what she means Li Su is also a prince, and now he is a vassal king, and it is not majestic to live in such a palace.

Although I know that the new palace has started, but Li Su has not been there, today I just went to see how the construction is going, this new palace is Li Su asked the modern design institute to design and plan, it is definitely carefully planned, including the pre-embedding of various pipelines have been designed in advance, electric lights, air conditioning, socket reserved ports are all available, he transported eight mobile power stations four to Taoyuan, one to the Military Academy, one to the School of Government, one to the medical school, and the remaining one is left for the palace, It's really hard to have a bad time without electricity.

Before going to the new palace, Li Su slipped to Su Mo'er's yard, Su Mo'er told him that Cui Yingying asked someone to dig a well for her, Li Su thought to herself that this Nizi was really thoughtful.

"Do you miss me!" After asking about the well, Li Su became dishonest again, and his hand moved around Su Mo'er.

Su Mo'er glanced at Li Su and said, "Your Highness, let's go and do business, it's not a joke to let people see it in broad daylight." Like Cui Yingying, Su Mo'er had a hint of a housekeeper's tone in her tone.

Li Yu took advantage of it, so he left the courtyard and went to the new palace, as Cui Yingying said, the new palace is almost next to Baihuatan and occupies a square of land.

At this time, the new palace is laying the foundation, a qiē has just begun, the wood has just been transported in, the carpenter is making all kinds of various constructions, these timbers are transported from all over the Tang Dynasty, so the prosperity of Yizhou is not one-way, it is not that Li Su has been making money from other places, but a win-win situation, Yizhou also buys a lot of things from other places at the same time, wood for construction, shipbuilding, spices for perfume, coal, iron ore, although Yizhou also has these ores, but it is not enough for Li Su to mine them himself, And the more these things, the better, and he doesn't have too much.

The construction site was still relatively empty, and Li Su saw Cui Yingying at a glance, she commanded the drilling rig team to drill a well in one place, and a person standing next to her was holding a drawing.

Li Su walked over, and when she saw Li Su, Cui Yingying had a smile on her face, and waved at Li Su from a distance.

"Your Highness, this thing is really amazing." Cui Yingying pointed to the drilling rig and said.

Li Su smiled: "That's natural, this is a high-tech commodity from Luo Anguo, how many have you played?" ”

"Two have already been beaten, and there are still ten." Cui Yingying said.

Li was stunned: "So many!" ”

Cui Yingying explained: "Your Highness, this palace is not small, and after the palace is completed, the number of people in the palace will definitely increase, and there will definitely be a lot of water at that time." ”

After a pause, Cui Yingying said: "There are many separate courtyards in this new palace!" If His Royal Highness takes a concubine in the future, these courtyards must have separate wells, right? Cui Yingying glanced at Li Su meaningfully......
