In June 633, Xia Xue gave birth to a second son, and Li Shimin was extremely happy and named his second son: Li Zhen. Why did Xia Xue always choose to give birth to a boy, because she felt that the ancient emperors could only choose from a few princes, and they needed to choose the best, and only one had no choice, and once there was any accident, the royal inheritance would be broken. Therefore, she decided to continue to give birth to boys, although she also liked girls, but the concept of the ancients was like that, the emperor could only do it with men, so she had to temporarily follow the customs.

In the children's education, Xia Xue of course tutored them herself, and she would teach them cultural knowledge and concepts that no teacher knew in this era, such as mathematics, physics, chemistry, etc.; For example, the concept of attaching importance to the ocean, the concept of attaching importance to industry and commerce, the concept of attaching importance to science and technology, etc., are very inconsistent with the traditional concepts of ancient times, but Xia Xue wants to let her children have a concept ahead. For educating children, Li Shimin certainly supports Xia Xue's idea, because he knows that Xia Xue's profound knowledge is unparalleled, but he will appropriately invite some erudite masters to tell children about history and teach them to write calligraphy, this Xia Xue also agrees, because his level of calligraphy characters, traditional Chinese characters, and ancient Chinese is indeed not good. After their children are 6 years old, regardless of boys and girls, Xia Xue will specially hire martial arts masters for martial arts training, including ancient horseback riding, archery, spearmanship, knife skills, sanda, grappling, etc., Xia Xue deeply knows how important a strong physique is to life, and when the age reaches the age of 12, Xia Xue will personally train them to climb mountains, swimming, diving, wild survival and other skills, these skills have saved Xia Xue many times, Xia Xue must also let her children learn, must not let children be a helpless chicken" nerds". These physical exercises can cultivate children's resolute and resolute character, and Xia Xue knows that the courageous and resolute character of no matter whether it is male or female, whoever has it will benefit in his life. The body, mind, and will must be strong in order to be truly strong and successful in education, which is Xia Xue's educational philosophy.

For the education of the citizens of the former Angel Country, Xia Xue is only for children or adults who voluntarily learn, and they can study for free for 1-2 years in the schools built by the state, mainly teaching the reading and writing of 2,500 commonly used Chinese characters and simple arithmetic learning, and there is no high ambition to implement 9 or even 12 years of compulsory education like later generations. First, the country's financial resources are insufficient, and there are not enough teachers; Second, the learning atmosphere at that time was not high, and many people were unwilling to read, and they were not willing to let their children study, and if they were forced to study and study, it would be counterproductive. She didn't teach chemistry and physics, firstly, because there was a lack of teachers, and secondly, she didn't want to spread these advanced knowledge of later generations too early, if people from other countries learned it, it would pose a threat to the angelic kingdom. These advanced knowledge of physics and chemistry are as confidential as glass production at present.

For qualified workers recruited to work in Tianshi Company, Xia Xue will only teach them the operational knowledge related to their work according to the needs of their work; For technicians, only teach the experimental operations related to their work, and do not teach them why this is the case, that is, do not teach them advanced theoretical knowledge, she feels that the current theoretical knowledge does not need to be developed, and what she has mastered is the most advanced scientific theory that has been accumulated and verified by human beings for more than 3,000 years, so there is no lack of theory now, but there is a lack of practical manufacturing to turn theory into physical products. At present, what is most needed is to manufacture physical objects, machines, and products according to the needs of oneself and society, and turn Datang into a world factory that produces high-tech products.

Therefore, many workers in Xia Xue's angel company are actually not very literate, and Xia Xue does not need them to be highly educated, as long as they can master the skills and related knowledge required by their factories and workshops, such as: length measurement units, she uses the meters, centimeters, decimeters, millimeters, etc. of later generations, and does not use ancient zhang, ruler, and inch, because she feels that the measurement units of later generations are more accurate. Therefore, the workers who enter the angel company must learn to use the meters, centimeters, decimeters, and millimeters made by Xia Xue, as long as they learn these, and other advanced theories do not need to be learned. For example, fitters only need to be proficient in chiseling, filing, sawing, scribing, drilling, reaming, tapping and threading, scraping, grinding, straightening, bending and riveting, etc., even if you are not literate.

In Datang, she still implements the same education policy as the Angel Kingdom, voluntarily learning, only learning the most basic literacy and arithmetic knowledge, and the schools are mainly concentrated in towns and cities, because at present, Datang is in ruins, and there are many places that need to use "people, money, and materials", and literacy education can only be done within its means.

In 634 A.D., after more than 5 years of construction, the southern capital of Haijing was preliminarily completed according to Xia Xue's plan, which was the world's first relatively advanced world metropolis built according to the urban model of later generations.

The wide road, which can pass side by side with 10 horse-drawn carriages, is hardened with concrete, and the road is lined with green trees such as plane trees, camphor, zelkova, ginkgo, and acacia trees.

Drainage facilities such as very tall sewers have been built under the city, and a truck can drive into the next generation, so no matter how heavy the rainstorm is, it is not afraid of clogging up the waterlogging. Moreover, the rainwater and sewage separation and drainage mode of later cities was implemented. That is, the water discharged from domestic sewage such as kitchens and toilets goes through one sewer, and the rainwater goes through another sewer alone, which relieves the pressure of the rainwater channel to a certain extent and reduces the probability that the rainwater channel is blocked. In order to prevent domestic and industrial sewage from polluting the water of the Yangtze River and Huangpu River, Xia Xue designed several sewage treatment plants in advance, and the water from Haijing's sewage pipes first flowed into the sewage treatment plant, and then discharged into the Yangtze River and Huangpu River after physical and chemical treatment and purification.

In order to ensure the cleanliness and hygiene of Haijing, Xia Xue has set up a sanitation department, employing personnel to clean urban roads and parks, collect and transport garbage, etc., and also set up several garbage treatment plants in the suburbs to recycle and process the garbage generated by industry, life and production, medical and health care, etc., so as to reduce environmental pollution. At present, Xia Xue's commonly used waste disposal methods include: sanitary landfill method, composting method and direct incineration method.

She is also building a large thermal power plant on the outskirts of Haijing City, which can provide electricity to this emerging metropolis of Datang, so that many shops, hotels, and street lamps can be lit up at night, highlighting the advanced technology and bustle of Haijing metropolis.

In addition, she chose to build several urban water supply sources in Haijing in the upper reaches of the Huangpu River, the Yangtze River estuary, Qingcaosha and other places, which can supply enough water for the daily life of more than 10 million urban people.

And the construction of several waterworks, the water from these water sources to further purify, through the erection of water pipelines into the company, hotels, shops, households, due to Australia's rich copper resources, Xia Xue simply in Haijing all use copper pipes as tap water pipelines, because copper pipes have a natural sterilization effect, in addition to long life, no rust, is the best urban water pipeline, is expensive. As for the faucet, it is also made of all copper, and the luxury is luxurious to the end.

The toilets in Haijing are also all clean and hygienic water-flushing toilets, unlike the dirty dry toilets used in other cities in Datang. In the superior rooms of the Angel Hotel and Angel Hotel built by Xia Xue, even more advanced siphon flush toilets are used. Due to the improvement of petroleum refining technology, plastic products such as synthetic resins have also been successfully developed, but the current output is not large. Rubber processing, ceramic product production, these are not a problem, so, Xia Xue set up a company to produce siphon flush toilets, specially for high-end hotels, guesthouses, wealthy families, royal bedrooms in other countries to provide, the price is very expensive, the profit is very high, but the sales objects are rich owners, do not worry about not selling.

Xia Xue also built a large public square in Haijing that can accommodate 100,000 people, named Haijing Square. In the center of the square there is a 320-square-meter circular fountain and a large green area of 80,000 square meters. The green meadows, numerous trees, and flowerbeds of large and small flowers are dotted with fountains, sculptures, art lampposts and stone chairs and stone benches, giving people a peaceful and casual atmosphere. In the western part of the square, thousands of doves of peace with white feathers rise and fall and hover, and the scene is quite spectacular. Haijing Square has become the geographical center, cultural and artistic center, transportation center and recreation center of Haijing City.

Also built Haijing Park, planted a large number of precious trees and flowers in the park, tens of thousands of begonias, magnolias, lilacs, bauhinia, snowflakes, mountain hemp poles, cherry blossoms, red maples, tulips, etc., the fragrance of flowers is pleasant, there are a large area of green lawn, full of greenery, fresh air, beautiful scenery, there is also built 140,000 square meters of artificial lake inside, the blue waves ripple, sparkling, the park is a group of birds and flowers, so that the people who come in are relaxed and happy.

Haijing's ports and wharves have all been built, with a total of 6: Yangshan Port, Waigaoqiao, Zhanghuabang Wharf, Yangpu Military Road Wharf, Longwu Wharf, and Baoshan Wharf. It can dock cargo ships of various tonnages, among which Yangshan Port can dock large ships of more than 50,000 tons, which can be said to be the only one in the world during the Sui and Tang dynasties.

After the city's public infrastructure was built, in order to make back the money from these investments as soon as possible, Xia Xue suggested that Li Shimin auction the land on both sides of the road at a high price according to the lot. In order to absorb the wealth of the world and reassure buyers, Xia Xue has specially formulated corresponding laws on fixed assets such as land and real estate in Haijing to ensure the legitimate rights and interests of buyers. Bidders who purchase the land at the highest price, regardless of nationality, will become their permanent private property, protected by Datang law, and the Datang government will issue a Datang land certificate to the buyer after the successful purchase. For the purchased land, the buyer also has the right to dispose of it freely, which can be leased, resold or inherited.

Although the auction price of land in Haijing is currently outrageously high, Xia Xue knows that in a few years, when Haijing becomes the largest and most prosperous international metropolis in the world and becomes the Pearl of the Orient, it will be a place where every inch of land is valuable.

Xia Xue calculated the account, if these lands are sold at a high price, then the money for the construction of Haijing will be earned, and there will be a lot of surplus, which is really a good deal. Li Shimin saw that Xia Xue auctioned the land prices of those Haijing at such high prices, and suspected that he could not sell them.

Xia Xuewan smiled: "Husband, wait and see, all of them will definitely be sold, and the auction price will only increase in the future, not decrease." ”

Xia Xue first drove her angel company into Haijing, bought land in many prime locations in Haijing, of course, her own is a private company, she also paid the money to buy land to the Datang government at the market price, and has a permanent land certificate issued by Datang, and the purchased land will become privately owned and can be passed on to future generations.

Xia Xue used his newly established angel construction company to build a 30-storey building using reinforced concrete and concrete near Haijing Plaza, the most prime location in Haijing, and the technology at that time could only be built so high, if there was a later technology, Xia Xue really wanted to build a skyscraper with hundreds of floors and a height of four or five hundred meters in the future, so that it would be more eye-catching and spectacular. And the building is specially equipped with an elevator, of course, the elevator is not as automated as in later generations, and each floor needs to be manned to open and close the elevator door.

The 30-story building of Xia Xue's angel company's Haijing headquarters was nearly 100 meters high, which could be said to be the tallest building in the world at that time. Glass doors, glass windows, electric lights, neon lights, elevators, Xia Xue dressed her angel company Haijing headquarters very trendy and beautiful, eye-catching, highlighting the company's strength, so that it can attract more business, merchants and partners in the future.

On both sides of the headquarters, several 20-storey angel hotels, angel hotels, large shopping malls, and magnificent decorations have been built. And Angel Headquarters has become the most eye-catching building complex in Haijing.

Near the headquarters of the angel company in Haijing Plaza, Xia Xue specially purchased a large piece of land and built a 25-story building ahead of time, which is lower than the headquarters, but higher than hotels, guesthouses, and shopping malls, and the decoration is super luxurious.

In ancient times, there were no banks, and credit institutions were mainly "money banks", which were mainly used for silver money exchange. But because Xia Xue came from later generations, she knew the huge power of capital, and knew the huge energy and rolling wealth of the bank, so she must be the first to eat this piece of fat. With the great prestige of the angel company, huge financial resources, strong background and unparalleled prestige and reputation, she soon launched a lot of new financial credit business to the business community and the public, in addition to the traditional "silver money exchange", but also for deposits, withdrawals, loans, transfers, savings and other businesses, angel bank's "ticket number", "silver ticket", "golden ticket" and so on are universal, because many foreign countries know the name of the angel company, Moreover, Xia Xue has opened branches of angel banks in major cities in various countries around the world, which are used for silver money exchange, etc., and the credit is very good, which also greatly facilitates the merchants and people of various countries, after all, most of the ancient currencies are gold, silver and copper coins, and the weight and volume are relatively large, and it is very inconvenient to carry. With an angel company with a thin paper made of special paper, with special anti-counterfeiting technology and seal of the "silver ticket", "gold ticket", etc., you can withdraw gold and silver coins in angel banks all over the world, how safe and convenient it is, and the money is stored in a 24-hour guarded, specially made ultra-strong anti-theft vault, than the gold and silver at home is safer, and deposited in the angel bank, it will also pay a certain interest according to the length of storage, safe and advantageous, can be described as killing two birds with one stone.

Reputable merchants who are in urgent need of money for the time being can go to the angel bank for loans, which also solves the urgent needs of many merchants, although they have to pay a certain amount of interest, but in fact the interest rate is lower than that of private loans, so soon after the opening of the angel bank, the business is booming, and the day is making money.

Xia Xue also bought a few plots of land in the suburbs of Haijing and built several very large freight warehouses, and she believes that her company's business will be very prosperous and busy in the future.

In the city center of some hotels and shopping malls and so on after the purchase of a large amount of land, built a lot of 6-8 floors without elevators of residential buildings, apartments, she believes that in the future there will be more people settled in Haijing, in Haijing, there are many workers, office workers, need to buy a house, rent a house, she advanced in Haijing first in Haijing to develop real estate commodity buildings, she believes that in the future, these not high-end houses will also be sold very expensive, because the location is good. She's going to make a lot of money.

Xia Xue knew that with the land she bought, she would be super-rich in the world in a few years. "Hey, hey!" Xia Xue couldn't help but smile, being a superrich has always been her ideal.

She also built a printing house and newspaper in advance, named Angel Newspaper, and published the first newspaper since ancient times, "Haijing Daily". She knows the importance and commercial value of newspapers. Papermaking and printing are now very common industries, and the use of steam engines, electric motors, etc., is also a great improvement in the efficiency of papermaking and printing, and the cost is also greatly reduced. The Angel Newspaper adopts a folio with eight pages and is a large newspaper. There is a lot of content, including news, news, economy, current affairs, poetry, and even some novels, songs, advertisements, etc. Newspapers are a tool for propaganda and control of public opinion, and the potential for commercial value is huge, so Xia Xue will certainly not let it go.

Since the whole city of Haijing has electricity, Xia Xue set up a branch in advance to specialize in the research and development of various household appliances, named Angel Household Appliances Company. Its production: electric lights, refrigerators, air conditioners, washing machines, electric ovens, microwave ovens, induction cookers, electric water heaters, cameras, tape recorders, radios, records, audio, video cameras, movie players, televisions and other household appliances, due to the wonderful and unique efficacy and efficiency and convenience of the products, for many rich businessmen and wealthy people stationed in Haijing are very attractive, they have spent huge sums of money to buy, many other countries of the giant businessmen or the royal family, after the royal family heard the news, Also specially sent people to spend a huge amount of money to invite angel companies to build power plants in their country's big cities, and at the same time buy a large number of these wonderful household appliances, because Xia Xue has always insisted on strict secrecy and monopoly of the core technology, these can only be produced by angel companies of unique household appliances, and later brought a steady stream of huge profits and wealth to angel companies.

The headquarters of Angel Company settled in Haijing, which immediately caused a sensation in the business and corporate circles, because Angel Company is the first super enterprise in Datang, and no one knows its name and strength. So the rich businessmen from all over the Tang Dynasty have invested in Haijing, bought a large amount of land in Haijing, built shops, hotels, restaurants, and guesthouses, they saw that the headquarters of the Tianshi Company was so tall and majestic, and they also wanted to build, but they couldn't build it, so they had to come to Xia Xue to discuss and let Xia Xue's newly established construction company help build it, but Xia Xue excused himself that it was too dangerous to build a 30-story building and was prone to accidents, and scared them, it was too high and unsafe, and it was inconvenient to go up and down the stairs, saying that they could only help them build the safest building below 10 floors. These rich people had no choice but to agree, and they found that the building built by Xia Xue was not made of wood, but reinforced concrete, which could be very good for fire prevention, and they were not afraid of accidentally breaking out in a fire and burning the house. Therefore, there is an endless stream of wealthy businessmen who come to Xia Xue Construction Company, and the orders are scheduled for three years. Xia Xue doesn't want to build high-rise buildings for them, of course, she doesn't want their houses to surpass herself, and she must show the tall image of the angel company that stands out from the crowd and is the first in the world.

In order to speed up the construction progress, Xia Xue had to expand her construction team and set up several branches, of course, she must review the architectural drawings, some key technologies and precautions, she needs to train relevant engineers to ensure the quality and safety of the building.
