Three days later, Li You's first batch of soap and soap was released, of which one was one million yuan and soap was 200,000 yuan.

The costs of soap and soap are four cents and two cents respectively.

Haha... the cost is very low... but this is also because the purchasing power of the Tang Dynasty copper coins is not low. The materials required for Li You's soap and soap are not very high, so there is such a low cost now.

Li You planned to set the price of soap and soap to be 6 cents per piece, 10 cents per piece, and soap to be 3 cents per piece and 5 cents per piece. The price is not low.

But why did Li You set the price so low... Nothing... Li You never thought of making money by relying on these things. Li You had his own way to make money. He developed these industries just to cover up his way to make money and make the money he earned more reasonable.

So Li You does not need to make money by trading, it only needs to be popular.

But soap and soap have been made, so how can we make soap and soap popular? First of all, the price is low, and you must at least make it affordable for the people of the Tang Dynasty.

In terms of price, Li You believes that there is no room for further decline.

Then the popularity of soap this time should be second, and the second is publicity... In modern times, we have various publicity methods, Weibo, TV station, Internet, etc. But in ancient times, what publicity methods were there...?

If you want to know, you must understand the surrounding areas of Chang'an.

Chang'an was the largest city in the world at that time, with an area of ​​84 square kilometers, 9721 meters wide from east to west and 8651 meters long from north to south. The circumference of the entire Chang'an reached 36.7 kilometers, with more than one million residents.

As the world's first city with a scale of one million, Chang'an City's daily water consumption is very huge.

The water used by the people in ancient times was nothing more than two sources. One was well water from the underground, and the other was river water, canal water or lake water on the surface. Since the mining of groundwater requires a lot of manpower and financial resources, the water used in ancient times was mainly surface water, which is also an important reason why the city's location was close to the big rivers.

It should be noted that the drinking water used by residents in Chang'an is mainly groundwater, which is an exception in the cities at that time. This is because, first, there are sufficient groundwater in Chang'an, and second, because there are many dignitaries in the city, they dug many wells in Chang'an.

Although ordinary people do not have wells at home, there are public wells for every market and every temple. Therefore, residents mainly drink well water, while domestic water is mainly canal water.

Therefore, Chang'an also has the nickname "Wanjiajing".

These wells can be divided into two categories: brick-wall wells and earth wells. The so-called "brick-wall wells" means that the well walls are made of blue bricks, and there are foot holes that can be chiseled on the walls to facilitate dredging of the silt at the bottom of the well every once in a while. Its advantage is that it is relatively durable, but it is cost-effective and is generally only used by wealthy families. Those earth wells are drilled down the ground with a depth of about five meters, and directly fetching water, which is more cost-effective and time-saving, and are mostly used by ordinary people.

The amount of water used by ancient people is incomparable with the amount of water used by urban residents today. There was no industrial water use in ancient times, and the water used by residents' daily water use was far lower than today. Therefore, although Chang'an has a large population, the urban water network of "eight waters and five channels" and these numerous water wells can fully meet the needs of Chang'an City.

It’s helpless, but you still have to pound it. You can’t let your men and children go out in dirty clothes... You can still wear this piece after a slit.

Just as everyone comforted the woman, a burst of foam floated from a distance, with some slight fragrance in the foam.

"What is this..." a woman pointed and everyone looked over.
