After King Sima Ying's attempt to seize Jin Huidi and Sima Jing failed and ended in failure, his generals, Zhao and Wei, wanted to avenge Sima Ying. Shi Le and Qu Sang led the herders to ride the horses to respond. When Gongshi Fan failed to attack Ye city and was killed, Shi Le and Qu Sang fled back to Ma Mu. They raided the county at Ma Mu, released the prisoners, gathered the fugitives from the mountains, and expanded their influence. Shi Le and Qu Sang were defeated in a battle, and Qu Sang was killed by Jin Jun. Therefore, Shi Le led his team to Liu Yuan, who was already known as the King of Han in the left country.

After Shi Le went over to Liu Yuan, in a span of three to four years, he went to the east to fight for power, attacking cities and seizing territories. He contributed greatly to the Han Empire and became a strong army that protected the rule of the Han Empire. Shi Le's power was also constantly expanding during the battles. In 311 A.D., after his power was expanded, Wang Mi, who had gone to Liu Yuan, plotted to kill Shi Le and annex his power. After Shi Le found out, he schemed to kill Wang Mi and merged with his men. As his strength continued to increase, Shi Le's ambition to call himself king gradually rose. But on the surface, he still followed Han's policy of giving preferential treatment to Han landlords and intellectuals under his rule, and absorbed a group of Han landlords and intellectuals under his command. His advisor, Zhang Bin, was one of them. Zhang Bin played an extremely important role in helping Shi Le establish a "post-Zhao" regime.

Not long after, Prince Chun and the others came back with Wang Jun's messengers. Shi Le ordered the strong and sturdy troops and weapons to be hidden, showing that the warehouse was empty and the army was weak. As for the messengers who went to meet Wang Jun in the north, they accepted Wang Jun's letter. Shi Le pretended not to dare to take the horsetail whisk that Wang Jun had given him and hung it on the wall. Shi Le had even sent Dong Zong to submit a letter to Wang Jun, agreeing on a date to personally go to Youzhou and present the title of Emperor. When Wang Jun's messenger returned to the Youzhou, he told the story of how Shi Le was weak and heartless. Wang Jun was overjoyed, thinking that he could be trusted.

"What is it? General Zhao Gaoyun was unable to resist?

"How can Chidan's army persist for long in such a small place?" Quickly come with me to the emperor to discuss countermeasures! " With that, Chen Tian and Huang Chongyang hurriedly left the Han Lin Courtyard.

The reigning city was a fortified military fortress. It was a defensive fortress in the north. It was the place where all the generations of soldiers would fight for it.

Speaking of the city, it is located in the southern Maowusu Desert, on the north bank of the Minding River, about 50 kilometers south of Jingbian County (that is, the Zhangjiafang area), and 120 kilometers east of Yulin. Xia Fengxiang (413 A.D.) Hun Lien's hundred thousand citizens built the city of Da Xia as the capital of Da Xia, with the name of "the reigning city", which meant "to unify the world and rule over all the states." The first four years of Northern Wei was 427 A.D.), when the Martial Emperor Tuoba Dao attacked and set up Wan Tong Town. The site of the city was a light gray, standing tall in the middle of an endless desert. From afar, it looked like a group of buildings, with the scene of a mirage. The southern gate famous dynasty Song, the western gate famous clothing cool, the east gate famous recruitment Wei, the north gate name plain Shuo. The inner city was completely intact. The outer city was 492 meters tall, 527 meters in the north and south, and 10 meters tall. There were tall towers at each corner, reaching a height of over 30 meters. The four walls were equipped with a defensive horse-mask equipment. The east, west and north sides each had seven horse-mask equipment. There were eight south of the city, and four gates were all equipped with a city of jars. The four city walls, as well as the architectural remains of the clock tower and drum tower in the city, have numerous and extremely sturdy storeys, making them one of the most complete ancient city ruins in existence in China.

In the history of China, during the period of the sixteen kingdoms in the East Jin Dynasty, there was a famous battle between the Northern Wei Dynasty and the Grand Xia Empire. At that time, the southern part of China was ruled by the East Jin regime, while many independent and independent regimes were established in the northern part by the minority nationalities such as the Huns, the Xianfu, the Karma, the Qiang and the Qiangqi, as well as the Han. The Northern Wei and the Grand Xia were two of these ethnic minorities in the government. In these independent regimes, the Northern Wei gradually became stronger due to its ability to impart advanced technology and culture to the Han nationality and its emphasis on the development of agricultural production. The Northern Wei started to unite the North as well as develop its own power in the south. The war between the Northern Wei, which took place in the first four years of the Northern Wei Dynasty (427 AD), and the domination of Wan Cheng by the Da Xia Empire was the battle launched by the Northern Wei in order to unify the North. In this war, the new Subordinate Tribe's Tuoba Dao had a deeper understanding of his grandson's fighting philosophy. Facing the attack on the ten thousand cities, he was decisive and nimble in commanding the battle, avoiding the difficult situation of falling into a prolonged, difficult situation of going forward or retreating, thus he completed this war well, and pushed the process of going from split to unified in the north. In the end, the Great Martial Emperor of the Northern Wei Sect, Tuoba Dao, managed to lure the enemy out of the city and seize the opportunity to quickly finish the battle. He defeated the Lord of Xia, Helian Chang, and dealt a devastating blow to the Da Xia Empire. They took over the entire city, and set up the town of Wan Tong here.

Da Xia Empire was established in the year 407. At that time, the north already has the south swallow, the back swallow, the north swallow, the north cold, the north Wei, the Qin and other independent separatist regime. Before the founding of the summer, Gao Ping, who had gone to the Qin Dynasty for help, was found to be a general in the Qin Dynasty, and was not accepted as a son-in-law. Afterwards, with the excuse of hunting in Gao Ping as the reason, Helian Jin plotted to assassinate his father-in-law, making his territory and subordinates his own power. On this basis, he established the Da Xia Kingdom. After Helian Lie founded his country, he did not use Gao Ping as his base of operations. Instead, he used the method of mobile attacks to nibble away at the Qin territory and expand the scope of his rule. Soon after, East Jin Liu Yu exterminated the Qin Dynasty, and Helian Lie seized the position to occupy the Northern Imperial Capital of the Qin Mountains, seizing Chang'an. Under the support of the more powerful military forces, his domination was consolidated and developed, becoming a formidable foe of the Northern Wei and obstructing its unification of the Northwest region.

On the basis of the consolidation of his rule and the gradual expansion of his territory, Helian Ming decided to locate his country in the capital of the city of Jong Wan-cheng, which is now the South White City of the Wuzhi Banner of Nei Mongol. In 413 A.D., the 100, 000 people of the Northern Huhan Nationality of Helian were established in the city of Wancheng. He drove them to build cities out of cooked earth, and when they were built he stabbed the earth with an iron spike, and if he stabbed an inch he killed the builders. Under his violence and pressure, the city was built to be extremely sturdy. It was ten feet tall, thirty steps thick, ten steps wide, and five feet tall. Its firmness could be used to sharpen (sharpen) a saber or axe. Helian zealous to use this strong city to resist foreign invasion, to continue its brutal rule.

The Northern Wei Dynasty was founded by the Tuoba people in 386 A.D. and ended in 534 A.D., with a history of 148 years. The capital city was first established in Pingcheng, which is now the same as the present one, and then moved to the Luoyang. The Northern Wei was founded in the first month of the year of Xiaofeng (386). It was initially named as Daiguo. It was renamed Wei in April of the same year. It destroyed the Northern Cold in 439 and unified the Northern Cold in 439. It was first governed by Toddler, then by Yuan, until 534 split into East Wei, West Wei, all governed by Yuan. In the early years of the Northern Wei Dynasty, the Yan Dynasty was the most powerful country in the Yellow River Basin at that time, while the Northern Wei was surrounded by the Yan Dynasty. The Northern Wei rulers paid attention to the combination of military and production, stabilized the agricultural economy under their domination, absorbed the advanced culture and production knowledge of the Central Plains, and placed great importance on the intellectual of the landlords of the Han nationality, thus developing into a relatively powerful regime. In 396, the troops of the Northern Wei Dynasty descended from the south and took over the, Chang Shan, Xin Du and Zhong Shan of the Houyan Town. Since then, the back of the swallow was cut off into the north and south, namely the Southern and Northern Swallow. Soon after, the Northern Wei began to implement its grand plan to unify the North. In August of the year 428, Sharjah Lien died of illness, and the princes fought against each other. The next year, Helian Chang won the right to inherit the throne, but the internal conflict of Da Xia Empire was even more acute.

In September, 426, the Lord of the Northern Wei Dynasty, Tuoba Dao, ordered Xi Jinping to lead 50,000 troops to attack Pu Ban (west of this mountain), and to attack Chang'an (west of Xi'an); he himself led 20,000 cavalry soldiers out of the city of Pingcheng (capital of Wei, west of the mountain) and crossed the Yellow River to attack Wan Cheng. Xia Yinhe led his troops to meet the enemy, but was defeated and forced to retreat to the city to defend. The Wei army divided the troops into four raids, drove more than a hundred thousand cattle and horses, captured more than ten thousand summer residents and returned, made a tentative strategic attack.

In December of that year, Xi Jinjun led his army to seize Chang'an. In the first month of the following year, Helian Chang sent his younger brother, Helian Ding, to bring down twenty thousand soldiers in an attempt to recapture Changan and restore the fortress to its former glory. The two armies were in a stalemate near Chang'an. Taking advantage of the advantageous situation where the Chinese army was being held back, the Wealthy Master Tuoba Dao decided to use the close to one hundred thousand army to attack the ten thousand city once more. In May, Tuoba Dao led the troops westward, with thirty thousand cavalrymen as the vanguard, thirty thousand infantry as the backup, and thirty thousand infantry as the transport of siege equipment. The Northern Wei army crossed the Yellow River from Yinjin to Jianshan (now in Inner Mongolia) to build a city and repair it. The leaders of nomadic peoples in the south of Inner Mongolia and northern Shaanxi province, originally attached to the Xia Dynasty, have successively descended to the North Wei Province. At this time, Tuoba Dao of the Northern Wei Tower changed his footwork and advanced with his cavalry. He decided to ride thirty thousand light cavalry to the Thousand City as fast as possible to lure the enemy out and annihilate them. They thought that since the Thousand City was strong, the enemy must guard the city well. The thirty thousand cavalrymen were not enough to break through the city walls, and it would be best if they waited for the infantry to arrive before bringing their siege equipment to attack. Tuoba Dao explained: "Using troops to attack a city is a low priority in military matters. It is only used when there is no other choice. If we wait for the infantry and the assault equipment to be ready, and then attack the city, the enemy troops will surely defend the city and not dare to fight. If we attack the city, we will not be able to last for a long time. For this reason, it is better to go straight to the city with the light cavalry. When the enemy sees that the infantry of my army has not yet arrived, he will relax and I will be able to lure him into battle with weakness and annihilate the enemy in one stroke. Furthermore, the reason why our army is suitable for light cavalry and decisive battle is because it is difficult to lose food and fodder after it is more than two thousand miles away from home and separated by the Yellow River. With the current thirty thousand cavalrymen it is not enough to attack the city, but the final battle is more than enough. " Tuoba Dao persuaded the troops, and the supervising army advanced.

In June, the Wei Army arrived at the reigning city. Tuoba Dao hid the army deep in the mountain valley at the north of the city. The Xia Army insisted on not fighting a decisive battle with the North Wei Army. At this time, Di Ziyu, a commander of the Xia Army, came forward to surrender to the Wei and to reveal the intention of the army. He had sent his men to Helian Chang to send Helian to send back reinforcements, and Helian believed that it was impossible for Wei to take over the city in a single attack. So he planned to defeat Yu and return to the Wei City after Changan, then attack the Wei Army from both inside and outside, and wipe it out in one fell swoop. As a result, Sharif and Lianchang adopted a policy of holding firm for rescue.

Coincidentally, a criminal soldier from the Wei Army escaped into the Xia Army and told them: "The Wei Army ran out of food, and the supply of supplies is at the back. The infantry also hasn't arrived, so it's better to strike quickly." When Helian Chang heard this, he firmly believed it. So he rode thirty thousand men out of the city to meet them. Seeing that the enemy had come out to meet them, Tuoba Dao was overjoyed. In order to lure the Chinese army deeper and further its pride, the Wei army pretended to retreat northwest. The Xia Army left the city to pursue the Northern Wei Army. At this time, the weather suddenly changed, a southeastern wind suddenly blew, sand flew into the sky, rain fell with the wind, Helian Chang's army was in favor of following the wind, thus taking advantage of this opportunity to fiercely attack the Wei Army. But Tuoba Dao firmly commanded the troops to do battle. In addition to sending troops to confront the enemy directly, he divided the cavalry into two teams, one on the left and the other on the right, and took a detour to cut off the Xia army's rear and counterattack from behind, turning the disadvantage into an advantage. Although Tuoba Dao was shot by arrows, he still fought valiantly with injuries. Under the desperate and fierce battle with the Wei Army, the Xia Army was killed by more than ten thousand people, Helian Chang did not have the time to return to the city, Helian Chang did not have the time to return, leading the remaining troops to escape to Gui (Tianshui City, Gansu Province). The Northern Wei army seized the victory and conquered the city. Helian Ding, however, was unable to take down Chang'an. The Northern Wei Army won the final victory in the Battle of reigning the cities.

Not long after that, the Northern Wei Army marched into Upper Gui, and China was annihilated.

It is not difficult to see from the war of Wancheng that the grandson's military strategy and tactics thought was not only used by the military commanders of the Han nationality in ancient times as a guide to command and fight, but was also highly respected by the generals of the minority nationalities in the regions affected by the Han nationality culture. From Tuoba Dao's understanding of the drawbacks of attacking Jiancheng, and from the decisions he made in this war, it is not difficult to see this situation. Tuoba Dao, the North Guard Chief of the Wupu Clan, has a deeper understanding of his grandson's fighting philosophy of 'winning the war and winning the war and taking it for granted'. In the face of the attack on Jiancheng, he was decisive and nimble in commanding the battle. It was precisely because Tuoba Dao was aware of the drawbacks of attacking the enemy from afar, that in the battle of the ruling ten thousand cities, the Great General of the Northern Wei, Martial Emperor, had used a strategy of luring the enemy out of the city. He took the opportunity to finish the battle quickly and seized the opportunity when the enemy's reinforcements had yet to arrive. They took over the entire city, and set up the town of Wan Tong here. This big battle, both avoid the attack, but also avoid the enemy's internal and external pincer attack, it can be said to be the use of the "Sun Tzu Yi Battle Chapter" guiding ideology of the success of the model.

On the other hand, the main reason for the Xia Army's failure was that its own slavery regime and its terror regime were unpopular, and its military and economic strength were weaker than the Northern Wei. However, as far as its military commander was concerned, Helian Chang's flaws in commanding and waging war were also very obvious. After the first attack of the Northern Wei Army across the Yellow River, the Xia Army still didn't pay attention to strengthening the strategic defense of the region in danger of the Yellow River. Instead, they split up their forces to gather troops and fortify the city to seize Changan, giving the Northern Wei an opportunity to launch an attack on the city. When the Northern Wei Army forced its way into the city, Helian Chang didn't seriously analyze the advantages and disadvantages of the quick battle.

Today, that is to say, four years (910) of Big Liang Kaiping. In the middle of April, Chidan invaded the Central Plains. On the 18th, the army reached all the cities and sent its troops to climb up the ladders and attack the city with all their might. Just think about it, this small city was far away at the northern border, and only had three thousand troops under the command of General Zhao Gaoyun to guard the city. How could this small place possibly stop Qi Dan's huge army? Although the city guards held their ground and bravely resisted, how long could they last like this? Very quickly, the city was destroyed, and the high city walls were torn open by the Chidan Thieves. From this gap, the warriors of the Chidan army began to climb up the walls and enter the city. After which, the north gate of the city was opened wide, and the army of Chidan marched in, killing anyone they saw and hacking at them. Blood and flesh were splattered all over the city in an instant, and it was like a scene of a pack of wolves. The first generation "General Double Hook" Zhao Gaoyun fought valiantly on the street with unparalleled bravery, fighting to the point where the Chi Dan Army soldiers that entered the city were forced to retreat step by step. However, no matter how hard he tried to kill the enemies, he only saw the city guards around him falling one by one, while the army of Chidan's bandits swarmed in like a tide, killing more and more. What was the fate of this city? What was the fate of this "General Double Hook" who could fight against thousands of enemies? Please break it down below.

Let's turn our heads and look at the Northwest direction of the PingPang Mountain, opposite to the south is the Pingshui City, at the Yungui border in the eastern part of the Wu Meng Mountain, the western part of Guizhou Province near the Yunnan border. And this Six-Coiled Mountain was also known as Longshan. Across the current Ningxia Hui Autonomous Region, Shaanxi Province, Gansu Province. Its main peak is located in Longde County, Guyuan County, Ningxia, at an altitude of 2928m. The mountain body is roughly the north and south direction, about 240 km long, is the northern part of Shaanxi Loess Plateau and the Longxi Loess Plateau, and is also the Weihe River and Jing River watershed, winding and steep. Since ancient times, there had been six levels of tunnels, allowing one to reach the peak of the mountain. This was why it was called the Six Pang Mountain. The southeast of this mountain has the old Dragon Pool, one of the sources of water.

At the northern end of the Six Pang Mountain Range, which is 55 kilometers northwest of Ningxia's Guyuan County, there is the world-famous Mount Xumi grotto. Here, the mountain range, craggy rocks, quiet and winding paths, is the "Chiming Immortal Cave to live in Zen" ideal place. From the beginning of the Northern Wei Dynasty to the Tang Dynasty, there were more than 130 grottoes, of which 20 were relatively intact. They were placed in five places, known as the Great Buddha Mansion, the Sun's Descendant Palace, the Rangguang Temple and the Peach Blossom Cave, which wriggled for about 2 kilometers. According to the characteristics of grottoes and statues, the grotto belongs to the North Wei Dynasty, which had three grottoes, a square chamber and a single chamber, with multiple pagodas, carved with one Buddha and two Bodhisattvas, and eight grottoes, which occupied an important position in the Xumi Mountain grotto during the Northern Zhou Dynasty. The chamber is square, but the central pillar has been converted into a multi-layered niche for a large niche. The statue is mainly one Buddha and two Bodhisattvas, but the decorations are magnificent, tall and grand, which is rare in North Zhou. In the Tang Dynasty, most of the caves were square, and the central pillar had disappeared. Among them, in the three years (AD 849) of the hole, Maitreya up to 20 meters tall, showing a grand and upright. In addition, there are the Tang, Song, Xixia and other times of many problems, is an important legacy of my Chinese grotto art. The three grottoes of China were: Dunhuang grotto, Luoyang Longmen grotto, and Datong Yungang grotto. If you added in the Xumi Mountain and Tianshui Mountain caves at the north end of the mountain, it would be one of the five major caves in China!

As for the old Dragon Pool in the southeastern border of the Six-Coiled Mountain, although it was not as exquisite and exquisite as the art in the Shimian grottoes at the northern end, it was still an ancient resort with a name that could be seen clearly in the history of the Qing Dynasty. Located more than 20 kilometers south of Jingyuan County, Ningxia, it is one of the source rivers flowing through Ningxia, Gansu and Shaanxi provinces. Here, the mountains and valleys were deep and serene. Pine and bamboo grew luxuriously, and the waterfall rumbled. It was a victory. The old Dragon Pool consisted of the upper, middle and lower three pools. The pool water was deep and biting cold. It was said to be the place where the Tang Dynasty's Wei Zheng Mengmeng killed the old dragon. The legend of the old dragon king of the Jing River mentioned in the famous book Journey to the West is also known as the old dragon pool at one of the sources of the Jing river. In the fifty-fifth year of Qing Qianlong's life (1790), Huche came here under the orders of Emperor Qianlong to make an inspection. He wrote a book called True Origin of Water, in which he wrote, "All the earth and stone mountains through which the water passes are clear and rippling, free of dregs …" "It is a clear and pure place, and it is something that we believe in after experiencing it." This gives a scientific explanation of the cause of the upstream water clearing.

When Genghis Khan led his army to attack Western Xia, he avoided the summer heat at the Six Pans Mountain of the Divided Mountains. In the end, he died from a disease and died in the army, aged 65, living for 23,725 days or so. He hadn't even lived for 30,000 days, so he was still short of thirty thousand days. A year 365 is 52 weeks plus 1 day or an additional 2 days for a leap year. If one lives 70 years, then one is 365 × 70 + (every 4 years a leap day is about 70 + 4 = 17.5 days) = 25550 days + 17.5 days, or 70 years is 3650 weeks and 17.5 days! So, we each look back and calculate, we still have many days in this world? He should be cherished!

Famous World War II film "Bridge" - the Yugoslav film song "Ah!" Friend! "Goodbye!" Middle Sing: "Ah! Wake up one morning from a dream! "AHH!" Friend! Goodbye! "AHHH!" Friend! Goodbye! "AHHH!" Friend! Goodbye! Goodbye! Goodbye! If I die fighting, please bury me on the hill! "AHHH!" Whenever people pass by, they always say how beautiful the flowers are! "

A beautiful flower in the river of history (1162-1227), a proud son of heaven, Genghis Khan, was also a wisp of heroic soul buried on a hill in troubled times.

Tie Muzhen, born in Mongolia, was born in the Tuer clan. He defeated the Tatars, the Teuchis, the Skis, the Zarukhar, the Klér, and the Nai Man, and united Mongolia. In 1206, a big party held by Timurid on the banks of the river was turned into a great Khan, the Genghis Khan. Then he began the great conquest, exterminating the cowards, the Western Lions, the flower models, and spreading the map to Central Asia and South Russia. The conquest of Western Xia in 1227 resulted in illness and death.

According to the Secret History of Mongolia, a year before the expedition to the Western Xia, Genghis Khan was suffering from a physical problem. He fell off his horse during a hunt and suffered a high fever. At that time, the plan to attack the Western Xia had been set. As Genghis Khan was not feeling well, he considered withdrawing his troops. But in the negotiation of the envoys, the general of the Western Xia was so rude that Genghis Khan fell ill with rage. He went to war with his illness, and although he ended up perishing of the Western Xia, Genghis Khan also died in the military camp.

Genghis Khan made a will and made a plan for the war. He would make use of Song Jin's enmity to travel through the Song Territory and exterminate the Yan family together with Song and Jin. And will the khanate divided among the sons, develop into the future of the Kinka, Cha Hat, and the abode of the three khanate.

The descendants of Genghis Khan, to Kublai, each stronger than the last. Taboo established the Kentucky State in Russia, and Montague fought all the way to Hungary as a "whip of God". Kublai founded the Yuan dynasty and ruled the world. For a time, the Mongol Empire became the largest empire in the ancient history.

However, like a flower on a prairie, she bloomed; a gust of wind blew her out. A generation passed, and another came. The Mongol Empire lasted no more than 200 years.

This was also a common problem in all empires.

Humans were like the flowers on the prairie. She blossomed, and when a gust of wind blew past, she was extinguished once again. A generation passed, and then another. Metabolism, the future waves of the Yangtze River pushing forward, the new people in this world chasing the old, this was the law of history.

The King of Anxi in the Yuan Dynasty also built a summer house on Liupan Mountain. On October 7, 1935, China's great leader, great mentor, great commander-in-chief, and great general helmsman led the Red Army's first front army from the Zhang's base in Guyuan, along the small river and through the Niu Tau Mountain Pass, and defeated the four pursuing cavalry regiments. The Six Pang Mountain was the last mountain over which the Red Army's famous 25,000 Li Long March had crossed one of the 18 mountains. On this very mountain, there was written the ancient poem "Qing Pingle Six Pang Mountain". Day of the poem:

The clouds were high and clear as they gazed at the flying geese in the south.

He was not a good man until he reached the city.

At the peak of the mountain, the red flag was fluttering in the wind.

With the long lance in his hand, when would he be able to bind the Azure Dragon?

Then there is the poem "The Long March":

The Red Army was not afraid of long journeys, only the easy ones.

Wuling through the Wu Ling Mountains, Wumeng Wuming Waves, Wumen Wuming Mud Pills, Muddle Pills, Muddle Pills, Muddle Pills, Mud-Mud-Mud-Mud-Mud-Mudders.

Jinsha water beat clouds, warm, the bridge across the cold.

More like the mountain of Minshan, a thousand miles of snow, three armies after the face.

"Some people, hold on while retreating! It's even harder to deal with than a stubborn donkey! "

Right now, at the start of the chaotic era of the five generations and ten countries of the Tang Empress, the Chidan army was pressing down on the border. According to the rules, the vice commander-in-chief Yang Neng, who was guarding the six pacts, was now the reserve army of the great marshal Zhu Weideng, who had sent an army of He Lan, and Marshal Zhu had already led his army of two hundred thousand Yellow River straight towards the front line — He Lan Shan Chuan!

Mount Helan, located in the northwest of Yinchuan, Ningxia, from northeast to southwest between Yinchuan Plain and Alashan Plateau. The length of the north and south is 200 kilometers, the east and west is 15 to 50 kilometers, the general elevation is over 2000 meters, the highest peak reaches 3556 meters. Its lofty and steep mountain is the natural barrier in the western part of Yinchuan Plain. And in the west of this flat barrier is the Alashan Plateau and China's fourth great desert, the Tengger Desert. Gazing at the Helan Mountain, like a fine horse, Mongolian horse for "Helan," the name. Xixia in Xingqing Mansion (Yinchuan City), there is a Western Xia Wang Mausoleum in the eastern foothills of Helan Mountain. Mount Helan is famous for its many monuments, such as Pen Rack Peak, temple and mosque, as well as lush woods, beautiful scenery, and gurgling spring water, which is a beautiful resort for sightseeing during the summer.
