Now that there are more pottery, the work of drinking boiled water must be fully popularized.

Although there is no industrial pollution in this era, there may be some bacteria and microorganisms in the water in the mountains and rivers that have not been boiled.

If Sangyu wants to improve the average life expectancy of the tribal population, he must pay attention to these things. The water must be boiled to drink, not to spit anywhere, not to be convenient anywhere, and to bathe frequently to prevent the growth of bacteria.

To do this, we must first solve the water problem.

From the day he arrived in Xindi, Sangyu began to plan to divert water to the households. But in the past few days, I have been making pottery and digging traps, so I have no time to spare.

Seeing that it has entered winter, the creek behind will soon dry up, and the water source is imperative.

It takes half an hour to walk from the bamboo house to the river across the mainland of Xindi Plain.

It is quite difficult to divert water from the river without pumps and waterwheels. Sang Yu decided to divert water from one of the stream branches of Dongshan Waterfall to the tribe.

In the evening, Sang Yu watched everyone eat to their heart's content, and began to arrange things.

"Tomorrow, we will temporarily suspend the work at hand. We will go to Dongshan to bring water to the tribe. The spring at the foot of the mountain is too small and the river is too far away. It will take time and effort."

"But leader, how do we bring the water here, should we use clay pots to catch it?"

"How many clay pots would that take!"

Sang Yu shook her head, "Use bamboo to divert water."

"There are bamboo joints in the middle of the bamboo, and the water cannot flow through it."

"Yu, bring the big bamboo in your hand."

Sang Yu said to Yu, and asked Yan to find a slightly smaller bamboo and sharpen it with a stone knife.

"Zhuang, you take the small bamboo and poke it into the big bamboo, and poke the inside at the bamboo joints."

When Zhuang Yi heard that he was asked to show his strength, he came up excitedly and asked Gao to fix the big bamboo tube for him, and then he took the small bamboo and poked it inside.

It was a bit difficult at first, but as the second and third bamboo joints were poked open, the small bamboo pierced forward under the action of thrust and inertia, and there was a crisp sound, one after another, everyone knew that the bamboo in the big bamboo tube Section is opened.

After Zhuang announced that all the big bamboo joints had been pierced, the two children, Qing and Bai, rushed forward, carrying the big bamboo tube at each end, and looked inside through the bamboo tube.

"Bai, I saw you." Qing was extremely excited.

"Qing, I saw you too, this bamboo tube is empty, water can flow in."

The rest of the adults and children all got up together, wanting to see this transparent bamboo tube, it was so novel.

Sang Yu turned her head to look at Yu. The little girl sat there motionless and did not get up to look at the bamboo tube.

"Why, aren't you surprised?"

Yu Yu looked at her with pitch-black eyes, and almost rolled them.

Sang Yu glanced at the little girl with some doubts, did she mean to despise herself?

Shouldn't everyone in this group of primitive people who have never seen the world be interested in this bamboo tube?

What's the matter with this little girl.

Look at other people, pick up the two transparent bamboo tubes and shout to each other, adults and children are like this, having a great time.

Sang Yu didn't bother with the little girl, and waited until they were fresh, and said: "Tomorrow, I will prepare such a big bamboo tube, and then connect them together to bring water to the bamboo house. I can use water whenever I want in the future."

"Listen to the leader. Get up early tomorrow morning to burn bamboo."

In the morning of the next day, everyone rushed to the bamboo grove and specially selected the largest bamboo as the water pipe. The young children were responsible for burning the bamboo.

The rest of the people carried the bamboos up the mountain, walked to the branch branched by Dongshan Waterfall, put down the bamboos, and arranged them one by one.

Wait until all the bamboo pipes are in place before connecting the water pipes.

The pipe sleeve made of big bamboo puts the two bamboo pipes together, and then wraps them around with vines to fix the position and go down layer by layer.

After all the bamboo pipes are installed, Yuan shouted at the position of the bamboo house, sending out a signal to release the water.

The people in the middle uploaded, and soon the people at the water source received the signal.

Sang Yu was at the source of the water, and when she heard the call from below, she said to the rock, "Let the water go..."

Hearing this, Yan pressed the head of the water pipe into the water, and the clear water rushed into the water pipe and flowed down.

Diqing on the side shouted to the bottom, "

Following shouts, from upload to bottom and then from bottom to upload, several people at the source soon received the news that the Xindi water had been connected in place.

As soon as the news spread, everyone was excited.

"There's water—it's water—"

At this time, Sang Yu was as excited as they were. In modern times, everything is in sight, always so relaxed.

But in this era of material and spiritual poverty, it is very different. Every process is pioneering and very difficult.

But the hard-won results make people more satisfied and excited.

"Press the water pipe with stones, and we will go all the way down and check the water pipe again to make sure that every link is connected."

Not only that, but after going back, we have to make a net to cover the water inlet at the water source, so that at least some leaf impurities can be screened out.

It took them three full days to receive the water. On the evening of the completion of the work, the children ran to the water pipes to solve the problem of domestic water. The next step was to build the bathhouse.

With the efforts of Yan and Jiao, two rows of simple bathing rooms were quickly built, men and women were separated, and a door made of bamboo and rattan was installed in each compartment of the bathing room, so that no one could peek at each other.

From the next water pipe on the mountain, it is diverted, one is connected to the bathhouse, and the other is connected to the cooking place.

There is also a laundry table built with stones next to the bathhouse. The table top is a few large bluestone slabs, which is convenient for everyone to wash clothes.

But now everyone has no clothes for the time being, and most of their bodies are covered with animal skins. They haven't found the saponins yet, so they can only wash with water.

A shower is also better than not taking a bath all year round.

But you can also use plant ash to wash your hair, something is better than nothing.

Sang Yu's next step is to persuade the tribe to take a bath frequently.

There are many reasons why primitive people do not like to take a bath. In addition to the lack of bathing conditions, another is that they think bathing will hurt their vitality and damage their bodies.

Sang Yu's biggest task right now is to get them to get rid of these thoughts and wash their hair and bathe frequently.

Wash it at least once every three days, and let’s talk about it when it snows in winter.

Zhuang was the first to refuse. He scratched his messy and tangled hair and said, "Is it okay if you don't wash it, I can work without washing it."

Sang Yu shook her head without thinking, "No, I'll get sick after a long time, and I won't have the energy to work then."

After finishing speaking, he looked at his messy hair and said, "Your hair is long and you have lice, don't you feel itchy, you have to shave it off."

Everyone wailed after hearing this, not wanting to shave off even the hair brought out of their parents' bodies.

Sang Yu said: "Those who take a bath and cut their hair today will have a rest day tomorrow without work, and those who insist on not washing their hair and taking a bath will deduct their dinner rations every day."

When it comes to this point, there is no reason for everyone not to wash up, and there is no need to work tomorrow. So I couldn't care about anything else, and instantly filled the bathroom.

Sang Yu looked at the little girl sitting motionless beside her and said, "Why, you don't want to take a bath, such a beautiful little girl, don't you want to become fragrant?"

Feather-black eyes stared at Sang Yu, as if looking at a fool, "Is it possible to squeeze in with so many people now? It stinks. Wait until no one washes it for a while before going in."

Sang Yu was not annoyed either, she smiled and patted her little head and said, "Your hair is so long, do you want me to cut some off for you?"

There are no scissors now, so you have to use a stone knife to cut your hair.

The little girl moved away from her instantly, and refused, "I won't cut it..."

Yu is a little girl who loves to be clean, she had no conditions and no awareness before. But since Sang Yu came, she often helped her watch the wind and let her wipe her body. Gradually, she also knew how to clean her body, washing her face, brushing her teeth, washing her hair, etc. Other children are also learning consciously or unconsciously , During this period of time, the health status of a small number of people has been greatly improved.

Just like Yu, the hair is soft, not dirty or messy, and you can touch it with your hands.

When Sang saw her like this, she no longer insisted.

Little girl, who doesn't love beauty.

As for those young and old, you have to pick one or two to demonstrate.

Sang Yu thought so, holding a stone knife and guarding the intersection from the men's bathhouse.
