Especially Wangcai, he followed Zhu Cilang to fight outside for many years. The conditions for the war were harsh, and Wangcai had a strange smell.

Whenever Wangcai wants to move forward, Zhu Cilang always kicks him away: Stay away from me, say what you have, and say what you have.

This is the tragedy of being a eunuch. Eunuchs have existed for about two thousand years since the pre-Qin period. Eunuchs serve the emperor and concubines. In fact, most of the time, the emperor is surrounded by palace maids and eunuchs, who can only serve them from afar.

Even a personal eunuch like Wang Chengen often maintains a certain distance from the emperor. Moreover, only people with status like Wang Chengen can obtain the qualification to take a daily bath.

When Wang Chengen returned to his bedroom, he had a small eunuch who specialized in serving him. For example, those eunuchs at the bottom of the house would not have such good luck.

The emperor had many concubines in his harem. In order to prevent accidents, an abnormal man could only serve the concubines here. Therefore, the position of eunuch appeared during the Qin Dynasty. In ancient times, eunuchs played a very important role in the palace. They not only had to help the emperor carry out tasks, but also helped the emperor issue an order.

Those who can enter the palace and become eunuchs are all children of poor people. After castration, they have to go through life and death difficulties. For example, some people will die after being infected.

Those who survive often have sequelae, that is, they are prone to incontinence. Zhu Cixuan built a canal leading to the palace in order to introduce tap water pipes in every room of the Forbidden City.

In this way, whether it is these eunuchs or palace maids, they can take a shower and change clothes every day. As long as they pay attention to personal hygiene, this problem can be solved very well.

Xiao Shishi loves to be clean, and her Kunning Palace is not allowed to enter most of the time. Generally, those who serve Xiao Shishi in Kunning Palace are all palace maids.

Xiao Shishi also complained to Zhu Cilang, saying that the eunuchs had an unpleasant smell. Zhu Cilang decided to change this phenomenon.

No matter how you deal with the eunuch, there is always a smell. This is why the emperor is served by palace maids when he eats, while the eunuch stands outside the door waiting for his master's order and cannot stand by his master's side at all.

Xishan Glass Factory has stopped production, and a large amount of glass is used to make glass tubes. In fact, the technology requirements of glass tubes are extremely high, especially the requirements for both ends must be strictly matched. This greatly tests the skills of craftsmen.

Then, the cement and iron smelting plants also started construction day and night. More than 100,000 civilians gathered, and they kept building bridges day and night. Sections of water pipes were finally gradually taken to the Forbidden City.

At the same time, a large number of tap water pipes have begun to be laid in the Forbidden City. Considering that the temperature in the capital is extremely low in winter, glass pipes are at risk of freezing and cracking at any time. Therefore, insulation has become a big problem.

There must be a sufficiently thick insulation material outside the glass water pipe. In this way, the taps will not be frozen. All the faucets are made of cooked copper. The main reason is that the pig iron technology is immature, and the melting point of cooked copper is lower and easy to cast.

Whether it is the room of eunuchs, palace maids or labourers, tap water pipes arrive at every room. At the same time, dozens of boilers were built in the Palace of the Forbidden City.

The purpose of the boiler is naturally to keep warm. It is impossible, every year, the concubines and nobles in the harem hide in the warm bedroom and enjoy happiness. Let the eunuchs and palace maids live in the cold bedroom.

The improvement of national strength has enabled productivity to be restored. The restored productivity has caused boilers to rise everywhere in the Forbidden City.

Small boiler, normal pressure boiler, normal pressure boiler, is also called pressureless boiler. There is a pipe port on the top of the boiler that communicates with the atmosphere and does not withstand the static pressure of the water column of the heating system.

It is a very open hot water tank, so the normal pressure boiler is generally not at risk of explosion.

Coal was used to keep heating, and cooked copper pipe radiators were used to make heating. First, the imperial court gradually implemented the decoding of copper coins, and replaced it with a large number of issuance of banknotes and banknotes.

Of course, blind issuance of bank notes can easily cause currency depreciation. This requires the court to come forward to control the number of bank notes issued.

After all, it is inconvenient to carry copper coins or silver. A large amount of copper coins or silver is a huge problem for those merchants and trade. Therefore, silver bills came into being.

At the beginning, silver notes were printed by private money houses. Later, the "silver notes" in the Northern Song Dynasty were the earliest silver notes in China and the world. The Yuan Dynasty mainly used silver notes, and the Yuan Dynasty inherited the Yuan system in the early Ming Dynasty. The "Da Ming Baochao" issued during the Hongwu period of Taizu of the Ming Dynasty used mulberry paper as the banknote material. The banknotes were one foot high and six inches wide, making it the largest silver notes in China.

Paper money was not printed in the early Qing Dynasty. Later, due to national difficulties, the "Ministry of Revenue Silver Notes" was issued, referred to as "official bills". Later, the "Da Qing Baochao" was issued, referred to as "Baochao". The denomination was complex and it soon depreciated sharply. By the end of Xianfeng, the official bills had become waste paper, and the Baochao was always worth only two or three months. After Tongzhi, the use of paper money was stopped and copper coins were still used.

In other words, silver notes have lost the trust of the public because they are prone to over-issuance and depreciation.

Now the imperial court has issued a decree to strictly control the issuance of silver notes. The issuance of silver notes is linked to the tax revenue of the state treasury. For example, the total tax amount of the Ministry of Revenue is now as high as 84 million taels of silver. Then, the amount of silver notes issued by the imperial court this year is only 84 million taels.

In this way, the depreciation of silver bills can be controlled. At the same time, the folk copper-minted coins will be gradually replaced.

These copper-cast coins piled up in the treasury and lost their circulation value. So Zhu Cilang decided to melt these copper coins and make cooked copper boilers and radiators to keep the palace warm.

The project that was originally planned for two years was completed in less than half a year.

The tap water that led from Yuquan Mountain to the Forbidden City Imperial Palace for dozens of miles was successfully completed. The trial operation was excellent, the water source was stable, and the water quality was sweet and delicious.

In the morning court of Huangji Hall, there was a tap water pipe that was taken over in the morning court. In front of all civil and military officials, the little legs were prosperous and wealthy, and the cooked copper faucet was turned on.

The civil and military officials were surprised to find that the Popo spring water flowed out of the faucet. Zhu Cilang ordered people to take a thick bowl and receive a bowl of water for every minister.

"Try it, all the Qing family will try it. This is the mountain spring water brought in from Yuquan Mountain dozens of miles away. Just gently turn on the faucet, the mountain spring water in Yuquan Mountain will flow continuously. You all taste it, is this water sweet?"

The officials had seen these things, so they picked up the thick bowls in their hands. No one could believe that the spring water in Yuquan Mountain was really led to the palace.
