Video spoilers history, starting with the blitzkrieg on Poland

A new sky screen appears.

The scene begins high in the sky over an endless expanse of golden desert.

The strong sun scorched the sand dunes.

The camera quickly swept across the sea of ​​sand, and on the distant horizon, the outline of a dark, towering mountain range like a giant dragon gradually became clear.

After crossing the Helan Mountain ridge, the view suddenly opens up!
The strong visual contrast hits instantly.

The Yellow River is like a green ribbon, winding through the vast plains.

The river surface sparkles in the sun, contrasting with the golden rice fields on both sides.

The commentary on the sky screen also slowly sounded:
[When talking about the Northwest, the first thing that comes to many people's minds is the desolate scene of lonely smoke in the desert and yellow sand all over the sky. ]

[But it is in this vast northwest land. ]

【But there is a magical place hidden that can change your fate. 】

[Ningxia means the wish for peace in the Xixia region.]

[Ningxia is clearly located deep inland, surrounded by desert.]

[It is a vast expanse of fertile land with rolling waves of rice. ]

[The land of fish and rice nurtured by the Yellow River forms a sharp contrast with the Tengger Desert next door. ]

[It has both the grandeur of the desert smoke and the gentleness of the small bridge and flowing water. ]

[It has both the ruggedness and boldness of the northern frontier and the elegance and poetry of the south of the Yangtze River.]

[Yes, this is Ningxia, known as the "Jiangnan on the Great Wall"! ]

[Ningxia, how did it break people's stereotypes about the Northwest? ]

【First, let’s look at Ningxia’s “source of life” – the Yellow River. 】

[This violent mother river has a special preference for Ningxia. ]

[The Yellow River, rushing down from the Qinghai-Tibet Plateau, has changed its turbulent state in Ningxia. ]

【Take a big turn at almost a right angle and gently embrace this land. 】

【It forms a unique "Jizi Bend". 】

[It is this magical bend that slows down the flow of the Yellow River in Ningxia.]

【The Yellow River makes Ningxia rich! 】

【This statement is absolutely true. 】

【The Yellow River not only brings water, but also brings fertile silt. 】

[Water conservancy and irrigation have also become extremely convenient. ]

[As early as the Qin and Han dynasties more than 2,000 years ago, our ancestors dug irrigation systems such as the Qin Canal and the Han Canal along the course of the Yellow River. ]

[In modern Ningxia, the area of ​​irrigation area diverted from the Yellow River exceeds 800 million mu.]

[The Yellow River water penetrates into every inch of land through crisscrossing channels like capillaries.]

【Let the inland northwest grow rice and lotus roots that are only found in the south of the Yangtze River. 】

[This makes the Ningxia Plain a rare rice country in the northwest. ]

[The golden rice fields and the scattered lakes and wetlands make this place look like a replica of the Jiangnan water town. ]

……

Outside the sky.

Han Dynasty.

When Emperor Wu of Han, Liu Che, saw this, he nodded in agreement.

"Jiangnan on the Saishang? The land of rice?"

"Yes, that's a very fitting nickname."

"Ningxia is a good place, and it is also very critical and important to the Xiongnu people."

"The loss of Saishang Jiangnan is a heavy blow to the Xiongnu!"

"And if our Han Dynasty can fully tap Ningxia's potential, it will be very convenient to raise troops on the northern front."

"Ningxia has indeed been blessed by the Yellow River."

……

The sky continues.

【But the Yellow River alone is not enough. 】

[If there were no Helan Mountains, Ningxia’s dream of becoming a Jiangnan city would have been swallowed up by the wind and sand long ago.]

[This north-south mountain range stretches over 200 kilometers from north to south, with an average altitude of over 2000 meters and the highest peak reaching 3556 meters.]

[It lies right between the Ningxia Plain and the Tengger Desert. ]

[Like a natural barrier, it blocks the Tengger Desert and Siberian cold current from the northwest. ]

[If there were no such mountain, the Ningxia Plain would have been buried by the sand and become the second Lop Nur.]

[The role of the Helan Mountains is far more than just preventing wind and fixing sand. ]

[Its peak is as high as 3556 meters above sea level, intercepting the moist airflow of the southeast monsoon and forming precipitation. ]

【The meltwater from ice and snow in summer becomes an important supplement for irrigation.】

[According to calculations, the Helan Mountains have reduced the sandstorm weather in the Ningxia Plain by nearly 60%, and the precipitation is more than 20% higher than that in the surrounding areas. ] [It can be said that the Helan Mountains are the "natural air conditioner" and "water tower" of the Ningxia Plain. ]

[Without it, there would be no lush greenery in the south of the Yangtze River. ]

【The Liupan Mountain in the south is like a green reservoir. 】

[Liupan Mountain has a humid climate and dense forests, with a forest coverage rate of up to 80%. It is an important water conservation area in the northwest. ]

[The Yellow River tributaries such as Jinghe River and Qingshui River all originate here]

[The water conserved by Liupanshui District flows into the Yellow River along the streams, injecting endless vitality into Ningxia's ecosystem. ]

[In addition to the protection of the mountains, Ningxia's geological structure is also full of magical places. ]

[The Ningxia Plain was once a huge graben basin during the geological history period.]

[The silt carried by the Yellow River is constantly deposited here.]

【It formed an alluvial layer several hundred meters thick.】

[This soil is not only fertile and loose, but also has good air permeability and water retention. ]

【Especially suitable for crop growth. 】

[What’s even more interesting is that there is a natural drainage network hidden underground in Ningxia.]

[Since the terrain slopes from southwest to northeast, the excess water after irrigation can be naturally drained along the terrain. ]

[It will not cause waterlogging and cleverly avoid the problem of salinization. ]

[This kind of land that can drain water by itself is a natural choice in the dry and rainless northwest. ]

[The unique climatic conditions make Ningxia an agricultural paradise where "God has blessed us with food."]

[This area has a temperate continental arid and semi-arid climate, with more than 3000 hours of sunshine per year. ]

【Sufficient sunlight during the day allows crops to fully photosynthesize. 】

[The large temperature difference at night can lock in nutrients. 】

[Watermelon is sweet, wolfberry is high in sugar, and even the flour ground from ordinary wheat has its own wheat aroma. ]

【Coupled with the dry and rainless climate, it is difficult for pests and diseases to breed. 】

[The use of pesticides is much lower than in other regions. ]

[Ningxia rice is therefore known as "tribute rice".]

[Ningxia wolfberry has even become a national geographical indication product. ]

[On one side is the vast Tengger Desert, and on the other side is a plain oasis with a network of rivers. ]

[On one side are the desolate ruins of the Ming Great Wall, and on the other side are the idyllic scenery of rolling rice waves. ]

【Scenic spots such as Shahu and Shapotou have brought this contradictory aesthetic to its extreme. 】

[The golden sand dunes and the blue lake complement each other, and the camel team and the cruise ship coexist in the same picture. ]

[From the gentle nourishment of the Yellow River to the solid protection of the mountains;]

【From fertile land to heavenly climate. 】

[Ningxia uses its textbook-level geographical advantages to support more than 700 million people, and writes a legend of win-win cooperation between ecology and development in the northwest desert.]

【Today, Ningxia is not only the granary of the northwest, but also a paradise for tourists.】

[The mystery of the Western Xia Royal Tombs, the antiquity of the Helan Mountain rock paintings, and the desolate aesthetics of the Zhenbeibao Film and Television City attract countless tourists to explore. ]

[Let Ningxia's reputation as "Water Town outside the Great Wall" become more and more famous! 】

As the video ended, netizens were still discussing it.

"The Yellow River has a hundred harms, but only one benefit: prosperity."

"Middle school students are very familiar with the Helan Mountains. Geography requires memorizing topographic maps."

"Drive a long car and break through the Helan Mountain Pass!"

"Is this how Ningxia got its name? I thought it was because of its peaceful summers."

"I've been to Ningxia before, the scenery is nice, the food is delicious, but the prices are a bit high."

"Me too. Last time I went to Ningxia, I took the airport bus and saw wetland parks all along the way. There are also several lake parks in the city. The city's greening rate is higher than that of ordinary cities in the south."

"The greening of the community is very good, and the temperature is really comfortable."

《Oh my god! Is it so good? The locals didn’t notice it, haha!》

"Welcome everyone to Alxa, the western foot of the Helan Mountains, which is completely different from Ningxia, haha."

……

And in the Southern Song Dynasty.

When Yue Fei saw the barrage on the sky, he blurted out the words "Break through the Helan Mountain Pass" and fell into a strong depressed mood.

"Ningxia and the Helan Mountains have indeed been the dividing line between the Han Chinese and the nomadic regimes of the grasslands since ancient times."

"Think about our Song Dynasty, we also once conquered Ningxia in the past."

"Touch the beautiful scenery of Jiangnan on the Great Wall."

"But now... there is only the real Jiangnan, ah!"

"How can the morale of the three armies be maintained and the food and fodder be sufficient? When will we have another chance to truly break through the Helan Mountain Pass?" (End of this chapter)
