This is probably the most amazing thing I've seen on KZfaq. Imagine if we spent money on doing something like this instead of spending trillions of dollars on war.

The ancient people were really ingenious. Without machines ,they produced what is marvelled the world over.

I was there and went into the Karez. They are incredible. Nice and cool (I was there in HOT August). Those grapes are so unbelievably sweet. No comparison to any others.

No matter who invented the Kaner well, ancient Chinese dig many 20-70 m vertical well on the slope of the mountain just by two hands. That is an amazing achievement.

That's why I love the Chinese. Very hardworking,planners n ingenious ppl.

Karez is a Persian word for underground canal. This form of water distribution was first devised on the Iranian plateau and then spread to other parts of Asia and Africa.

i am an Afghan... we also have this system in my village... its called "Karez"

in Morocco this system consists in transferring the water from the mountains underground in order to avoid evaporation and also it requires the maintenance its is called '' khattarat ''

I remember when I was a child my entire family and every home of the village, depend from a well, my father used to go all the way down to the well and clean up, water was very clean and taste a little bit of clay, beautiful.

this system is old and known by the Persians and Moroccan, in morocco, it is used now in the mountain of atlas to irrigate the fields and garden of Marrakech, and I believe that it was used in Andalusia at the time of the Arabs in Spain

We have a Karez irrigation system in Pakistan too. Its an underground system of canals which actually dates back to the era of Indus river civilization.

I like seeing ingenuity used to solve problems

In the Philippines we have our own natural rock water reservoir under the mountains. We just put bamboo on the side of the mountain where water leaks. Continues supply without experiencing droughts.

These were dug in the ancient times, incredible

Thank you CHINA for your contribution to protect environment and safeguard mother nature. The Earth is a better place to live in.

Hard working chinese peoples.....Showing the world that massive positive outcomes only need the will and support of the people. Amazing continuing results. I salute you all

I need more! it was just getting interesting.

We in Australia could really learn and innovate from this Chinese technology to combat our own water issues

There are plenty of traditional canals like that in the desertic south of Morocco, they bring water from the Atlas Mountains to the desert they are called "khataras" nevertheless, this is a huge achievement.

China is working on being around another 4000 years

While US spends money on wars, China spends on human development. Support from Pakistan. ✌🇨🇳🇵🇰

China is a great Country & a land of lovely people who believe in bringing prosperity to other poor nations by building roads, railways, bridges & ports. China makes investments in the other countries thereby enabling them to get the benefits of the trade and prosper, China and Chinese should not be distracted by all those crazy noises from the West but must keep on marching forward towards a more Prosperous Stronger United future. Huge Respects to the Mighty China from Pakistan, Iron Brother.

How i wish the video was longer and more detailed.😶😣

Like said in the video it's really an ingenious example of people "working with mother nature".

It's great to bring mother back nature to life.

Thank you for sharing. These are wonderful men who are working to keep their Village water safe. I love the fact that this was an ancient solution. I hope the men realize how much we appreciate their work and effort in this water solution

Real Leader of World and Great china Most Respected President Mr Xi jinping, Most Respect and Love From Your "iron Brother" pakistan...

It's really wonderful and I hope modern human beings will also understand that it's in the best interest of mankind to work hand in hand with mother nature. Quetta, Laptop. 1947, 05/12/2020.

I love this stuff

This is very similar to the well canal system in the Sahara in southern Algeria, the water feeds their date production.

People working with Mother Nature, a noble endeavour 👍

The kehriz system was used extensively in the middle east till very recently and those canals were dug out by men using picks and shuffles only. It was a way of transporting water from a spring to further places but now technology has replaced that where now deep wells are bored and water transported by pumps and pipes.

How can it be a "modern- day engineering marvel" and an "ancient irrigation system" at the same time ?

It's Old Iranian Technology of under water transport for irrigation. Same Technology is used in North Africa, Iran and western part of present day China.

Interesting and worthwhile video on a rather obscure topic in Chinese history and their ancient technology.

This system has been used in Iran for thousands of years and it is called QANAHT. That's a very economical way moving water from higher surfaces to lower ones. All they need to do in order to keep it for long time secure is to protect the walls and ceilings with premade armed and oval shaped concrete. And it just needs to be cleaned out of dirt once in a while. The best solution to have cheap and high quality water.☁☁☀☀

This system was used in the olden days when there was no electricity and pumps.

From the hat gear of one of the workers one can tell he is a Uyghur and his fellow workers may be Han or Uyghurs. They work and speak mandarin to each other. This scene belie the racial hostility situation often described by the western MSM in that area.

This method has been used in Iran 2000 years ago, there are 2 names for that : Cariz or Ghana. They dig a lots of wels ,starting near mountain and connect all these wels under ground together. Under ground it look like a small river water flows by gravity to the low land.

it's another great example of people remembering what works and continuing to use it in a sustainable way...

Great ideas transforming peoples' livelihoods for the better. All the best to you all people of God🙏🏻

These trees are not democratic. Some media will definitely report this way.

Those brave men descending into a hole in the ground- -heroes, indeed!!!

Holy Moly! That is incredible.

Some of these comments immediately turn the landscape engineering topic to an anti-China talk. Salty, period.

The USA spent twenty trillion usd just the last twenty years on wars.never on anything like this.

water and ecology are so valuable, currently the most ecologically important parts of the planet are maintained by the indigenous people that live there, and its vital we help them keep that land so they can continue their task, the destruction of places like the amazon is the peak parallel to the Greek myths of man falling to his own hubris, we can not expect to reap infinite reward from our finite existence

Ingenious and amazing work of modern China !!

So awesome, wish other places would think and work the same

People talking without knowing the difference between nationality and race. All races with China citizenship are Chinese. Hans are Chinese and so are Uyghurs, Manchus etc.

Wonderful maintenance of heritage

This system is common throughout NW China. The early inhabitants of the region were Sino-Tibetan, East Iranian and Tocharian (a misnomer by Early European scholars. They called themselves by the towns they lived, such as Tuti and Agni). The inhabitants were Indo-European Buddhist for millennium and Islamization started in around 10th century AD. They are now known as Uighur but this is also a misnomer as the real original Uyghur people spoke a Siberian Turkish language and believed in Shamanism. There are direct descendants of Uyghur living in Gansu who still speak the Uyghur language and are Buddhist. The Xinjiang Muslim Uyghur speak a Chagatai language which is almost identical to the Uzbek language.

This is also available in Arabia and called Aflage, in Oman and Saudi Arabia

An amazing achievement for ALL MANKIND, we should be so proud

We have spring fed creeks here in Central Mississippi. The water is sweet and clean. Most farms/plantations dig their own wells near their house. These old dudes, back in 1830, could dig a 150 foot well with mules.

This is a method that Uyghurs have been using on since very old times. The place shown in the video is in Xinjiang.

what's the possibilities of sinkhole forming? honestly that's the first thing that comes to my mind.

Love China From Pakistan ❤

This system has been developed in ancient Persia and spread to many neighbouring regions. Some karez in Iran are older than 7000 years and still working.

OMG! So wonderful! I really love this! Thank you so much!

Pakistan has world's largest Canal based irrigation system! Good Luck to our friend China 🇨🇳🇵🇰

There is a similar irrigation system in Africa. We may wonder for how two separated regions got the same irrigation system. Old global civilization ?

When there is no prejudice in the world, everyone accepts differences and seeks common ground while reserving differences, who can tell me what the world was like then?

Wanderful water 💦 is Very important to the pepole thank you very much for video 📹 happy evning to You.

Wonderful

This is a great project

And this is exactly the old Persian karez system concept. Today in Iran 1000s of hundreds years of water bores (qanat) are active.

Super !!! This is the healthy future 🌴🌿🪴🌵🌳🌴🌿🪴🌵🌴🌿🌵🌵🌳🌿🌴🌿🌵🌏🌍🌎🌏🌍🌎🌏🌍🌎🌎

Thats anciant persian tech speard to china through silk road. Like many chinese tech speard to mid east through the road.

Were these underground canals man make ? If so, amazing achievements.

What a brilliant idea

Watching videos like this, makes me even more thirsty for knowledge. I'm lost in the desert of stupidity.

When world mind stop working China let me think 😉😉😉😉😉😉

Koriz in Uzbekistan .

Wonderful way to combat the global warming and make the environment beautiful and sustainable for ordinary people of the region.

Amazing human ingenuity - living in an environment inhospitable without human engineering.

"坎儿井"

If USA can do this with the money spending on wars.

VERY VERY VERY GOOD!

This is what we call a GENIUS

This is not a solution to the drought problem this will only make it worse over time.

Happy they gave distinguished and nourished this technology from classical religious sperstitions. Long live china

Perseverance and hard work did the miracle 👍👍👌

At least I know that the satellite pictures aren't something weird going on! Good idea!

Oh man I'm so tired of those fight between Chinese and Americans everywhere Edit: westerns and easterns too

Imagine they digging this hundred of years ago!😮😮😮

What China has achieved over the 4 decades were not just its visible glittering buildings, and first-class infrastructure. For the inherent strength of China’s rejuvenation lies in its commitment towards sustainable growth and development with a focus on the environment and green technology. Similarly, China places great emphasis on the continuous development of humanity by the embrace of culture, science and technology as its priority. Over the last 40 years, China has increased its forest cover from just 12% to 23% now. When one takes into consideration that of China’s national frontier stretches some 9.6 square million kilometres, about the size of the United States. In other words, China has planted just over 1 million square kilometres of forest. That is the size of Egypt! China is also the only country in world which has successfully reversed the seemingly unstoppable desertification, by turning its desserts into forest, farm lands, and wetlands. The area of desertified land in the country is dropping by an annual average of more than 2,400 square kilometres, or 3 times the size of Singapore, compared to what used to be an annual average expansion of over 10,000 square kilometres at the end of the last century. By 2014, China had completed and commissioned its mid-line stretch of the South-North Water Diversion Project. This 1,300 kilometres dedicated, largely gravitational-flow, water supply channel diverts water from the Danjiangkou Reservoir in the upper reaches of the Han River, passing through mountains; crossing rivers; and finally reaching and transferring 9.5 billion cu meters of water annually to Beijing and Tianjin. To put that into perspective, the annual per capita water consumption of the Asian cities: Tokyo, Singapore, Seoul, and Hong Kong are at 84, 52, 104, and 80 cu meters per annum respectively; with the average consumption of 80 cu meters per annum. In other words, the amount of water transfer annually is adequate to sustain an urban population of over 110 million people with clean and potable water.

We call it "Karez" کاریز، it's also common in areas of Pakistan with similar climate zone. But we have almost driven by nature.

Imagine...as he ascended...and then you stop the tractor and you told him that the tractor is damaged.

The beauty of the Chinese mind....

So why don't they put in pvc tubes with a grate at the top?

High bred technology of indigenous ancient and modern professionalism procedural process can counter scarcity of water in desert regions , preventive and Conservation of water with distribution and diversion layout process with reservoirs systems . Yes prevention of flooding for disasters management too .

China will bring water from the flooded Altai Region into the Urumqi canal into the Talamakan Desert.and under ground exidting rivers.

I was like whew they have a cable and pulley at least, its legit. Flashes to man on riding lawn mower putting it in gear to lower him down....

Let’s make this world a better place……….more peace and prosperity.☮️☮️☮️

Very simple but innovative concept

Those were ancient han Chinese techs. China spreaded digging well techs to west regions. And han Chinese came to that region before urghur race came into existence. According to a 4000 years old poetry击壤歌 and other history books, The wells were used when Yao尧 ruled China.

This system is invited by ancient Persians. However, it has flow. High usage of water dries underwater supply.

great work

This type of underground water channel is still in use in iran and PAKISTAN from thousands of years it's called KARAIS
