It has to be mentioned that the underground construction of the new city, proposed by the Mo family, established a perfect water supply system and sewage system, of course, and later generations can not be compared, most of the messy latrines in the new city have been removed, all sewage measures are unified construction, each urban area to establish five to fifteen public toilets, public toilets are open to the public free of charge, and the person in charge of each urban area is responsible for cleaning and maintaining the order of public toilets.

In fact, the water supply system is not difficult, mainly according to the idea proposed by Liu Tai, the pumping pipe in the rural areas of the future generations is used as a template to compress the air in the underground well and extract the water source (I will not explain it in detail, I will not make up the numbers), and with this water supply system, it can solve the water supply problem in most urban areas.

Of course, it is not possible to feed the millions of residents of the new city by pumping groundwater, Liu Tai ordered the construction of dozens of large reservoirs in the mountains outside the city to store water, and with the steel technology of the Mo family, the water sources in the reservoir are connected from the underground to the major urban areas of the new city to supply water sources, these clear water are collected from the mountains, the taste is very good, there is a hint of sweetness.

Regarding the material problem of residential houses and commercial buildings in the city, Liu Tai originally suggested using reinforced concrete, after all, later generations proved that this kind of reinforced concrete house is the most solid, but the Han people of this era could not accept living in stone houses at all.

According to ancient records, the stone house was inhabited by the ancients thousands of years ago, and most of the people did not agree with this proposal, even the officials under Liu Tai could not accept it, not to mention the old-fashioned people, after all, they were used to living in a fresh and elegant wooden house, and few people accepted the novel stone house, and Liu Tai had no choice but to give up.

Subsequently, in order to maintain the mountain and forest environment around the new city, Liu Tai strictly forbade the people and the government to cut down the trees in the mountains without permission, because of the emergence of coal and stone heating, this was accepted by the officials and most of the people.

However, the timber needed for the construction of the new city was too much, and there was no choice but to cut it in Jizhou in the south, but fortunately, the Yuan family did not bother with Liu Tai, who was said to be in the sky, so they ignored Liu Tai's collection team.

In the past six months, a big thing has also happened, when Liu Tai New City was built, there were unscrupulous businessmen who traded with others with privately minted five-baht money, and after Liu Tai learned about it, he severely punished the businessman and expelled him, and he was not allowed to step into Liu Taizhi's next step for life.

However, after this incident, the privately minted five-baht coins appeared more and more frequently, and some people even purchased materials in the two states on a large scale and transported them to other states and counties, but fortunately, Liu Tai found it in time and did not cause major losses.

However, because it is difficult to distinguish the authenticity of the five-baht coin, Liu Tai is also helpless on this matter, after all, the five-baht coin is a copper coin, not paper money, there is no good way to test it, but when it comes to paper money, I have to say that Liu Tai also had the idea of exchanging all the five-baht coins under his rule into paper money, and in the two states, the paper money was traded, but this article was temporarily stranded because it was too difficult to implement.

However, Liu Tai did not give up on the change of coins, and instructed the Kyushu Commercial Bank and the Momen people to conduct large-scale experiments on paper, and researched the most difficult to imitate and low-cost paper as the new currency under Liu Tai's rule.

Of course, in order to curb the circulation of inferior five-baht coins, Liu Tai stipulated that merchants must pay gold and silver to buy large quantities of transactions, and then built a large pawnshop in Xincheng, which was named Huaxia Bank by Liu Tai, and the bank was mainly responsible for keeping gold and silver valuables for merchants, and only charged a small amount of custody fees.

As long as the merchant keeps the gold and silver valuables in the bank, he can enjoy a certain percentage of the discount when trading with the government, and the bank will issue stubs to the merchant to prove the quantity of the goods and the real surname.

Of course, in order to crack down on counterfeit stubs, Liu Tai specially ordered Momen to create a batch of seals that are extremely difficult to imitate, and based on the invisible ink invented by Momen (I forgot the exact name, but there has always been this kind of thing in ancient times, and the handwriting can only be shown after trying with water and fire or other things), and the serial number of the stub is marked on each stub, and each merchant can only have one stub, of course, there is no limit to the firm, and the people also have the right to deposit.

As soon as Huaxia Bank opened to the outside world, it ushered in countless merchants' deposits, after all, there are many businessmen who traveled thousands of miles from the Central Plains, even Yangzhou and other places to come to Northern Xinjiang to do business, with a large amount of gold and silver, very unsafe, often robbed by those thieves, now with Huaxia Commercial Bank, and Liu Tai's reputation as a guarantee, of course everyone can accept and love.

In less than half a month, Huaxia Bank deposited nearly one million taels of gold, tens of millions of taels of silver and countless other valuables (the deposit of five baht coins is not accepted), because Huaxia Bank has a limited area, it is impossible to store everything in Huaxia Bank, which is not only unsafe, but also not enough space.

Therefore, most of the gold and silver were all moved into the household department and the Tianci Marquis Mansion for storage, so much gold and silver deposited, suddenly made the original poor financial situation of the two states, greatly alleviated, of course, if the government uses this money, it will also give some preferential policies and subsidies to the merchants, and will not embezzle the gold and silver of the merchants in vain.

In order to alleviate the pressure on Huaxia Bank, Liu Tai opened eight more banks in the new city, of course, other states and counties have not yet begun to build banks, after all, Liu Tai's manpower is also limited, and it is impossible to cultivate so many banking talents at once.

Among them, there are also commercial banks that hope to come forward to open a private bank, but Liu Tai refused, after all, the bank is a place to store people's money, if the money is swept away by illegal businessmen and flees from other states and counties, Liu Tai has no place to cry, and if the bank is really delegated to the hands of businessmen, what Liu Tai has done in the past two years has almost become a businessman's wedding dress.

After all, Liu Tai has been working hard for the people of Erzhou to get rich, and when the people have money, they do not help the government, but send it to the pockets of businessmen to make money, is Liu Tai concerned? Or some people will say that when a businessman gets rich, it will naturally drive the production and efficiency of the two states, but the question is, if this is the case, wouldn't the initiative fall into the hands of the businessman? Is Liu Tai in charge of the two states in northern Xinjiang, or is it a businessman?

In Liu Tai's view, although the constitutional monarchy system guarantees the continuation of the royal family, it also restricts the development of the royal family, such as the emperor of an island country, although he is extremely noble, but he is just a canary in a cage.

Today's Liu Tai is just a marquis, and he doesn't think about those things at all, even if he has the heart to be the emperor and the ancestor, he has to wait until the Emperor Ling returns to heaven and the world is in chaos.

Half a year is not long, not short, after consultations from all sides, Liu Tai brainstormed and appointed Xincheng as Huacheng, the city of China! The name of Jixian County has naturally disappeared, but most people will not forget that the thousand-year-old capital of Yang Ming is located on the site of Jixian County.
