Why is Lanzhou a first-tier city geographically?



When it comes to Gansu, many people may talk about a few famous poems or a few scenes: the Yellow River far above the white clouds, the spring breeze not crossing the Yumen Pass, the desert sand like snow, the western corridor of the river, the desolate old fortress, the majestic Great Wall, the sun like blood.


Lanzhou, Gansu is located in the upper reaches of the Yellow River in a ribbon basin. The Yellow River cuts through the mountains and passes through the city from east to west, making it the only provincial capital city where the Yellow River crosses the city. It is the only provincial capital city where the Yellow River runs through the city from east to west. The north and south of Lanzhou are high mountains, and the city is about 30 km long from east to west, 1 km at the narrowest point from north to south, and 5-6 km at the widest point, making it a geographically “one-line” city.


Lanzhou Metro Line 1, which basically runs east-west, runs parallel to the Yellow River. Line 1 is about 26 kilometers long, with a section running under the Yellow River in the west, making it the first rail line in China to run under the Yellow River. Lanzhou Metro Line 2 is the same, and the basic pattern is east-west.


In the spring of 121 B.C. (the second year of Yuanxiao), Emperor Wu of Han Dynasty made Huo Baodi a Hussar general and led a dozen lieutenants and 10,000 cavalry to attack the western corridor of the river. The 10,000 cavalry, however, were equipped with 12,000 war horses, loaded with a large number of wooden shields, strong crossbows, arrows, long gorget and other weapons.


Huo Zhaodi’s men came to Longxi County against the Wei River, departed from Didao, followed the Tao River northward into the main stream of the Yellow River, and then turned eastward.


Li Xie, the great archer, had come to the bank of the Yellow River the year before to build the fortress of Jincheng (modern Lanzhou, Gansu), which means “golden city” and “golden city”. In the past few years, Li Xing supervised the construction of several cities and fortresses in Shuofang County, and he was very familiar with them. The company’s main business is to provide a wide range of products and services to the public.


In ancient times, when crossing the Yellow River in Lanzhou, few people used sheepskin rafts, but thousands of horses had to use pontoons, not only were there too few sheepskin rafts, but war horses were scared and easily overturned.


In just a few months, Li Xi, in addition to repairing the city, had already prepared wood and ropes, and was only waiting for the arrival of Huo’s army to set up a pontoon bridge to cross the river.


After crossing the Yellow River and traveling a few dozen miles against it, Huo’s men encountered the Wuting inverse water (now the Zhuanglang River) and turned against the Zhuanglang River to the north. The Han army could enter the western corridor of the river by following the valley of the Zhuanglang River and going over the Wutingling. The other way is like the northeast around the Uttering, so the road is much farther, and on the way to pass the edge of the Tengri Desert, and to cross several small rivers, the trip will add a few days.


This battle was a “tricky way for soldiers” strategy, to be fast and attack them unawares, so the shortcut was chosen.


Why didn’t Li Xi build the Jincheng fortress on the opposite bank of the Zhuanglang River from the confluence with the Yellow River? This would have saved Huo from having to go back and forth. In ancient times, it was dangerous to cross the Yellow River. The river near Jincheng is deep, the flow of the Yellow River slows down, and the river is also slightly narrower, making it much less difficult to cross the river on a sheepskin raft or to set up a pontoon bridge.


Along the Zhuanglang River, the Han scouts were out in force. This is the sphere of influence of the Qiang, who are mainly in the highland valleys around Huanghuang, and sometimes go to the Hexi corridor to herd horses and submit to the Xiongnu.


The snow and ice of the Zhuanglang River were melting at the beginning, and snowflakes were drifting in the mid-air in a solemn atmosphere. The first day of the month, the first day of the month, the first day of the month, the first day of the month, the first day of the month, the first day of the month. The company’s main goal is to provide a better solution to the problem.


Huo pointed to the mouth of a valley and said, “If we build a fortress here, it could rival the Gao Que fortress.”


Beside him, Zhao Bainu was distracted by the fact that Gao Buzhi and Servo were already lieutenants, but he was a lower ranking official, and replied, “Li Daxing (Li Xie) built a fortress, and it must be as solid as gold.




The place Huo said was later rebuilt as Lingjuese (west of Yongdeng in Gansu), which played a big role in monitoring the Hexi Corridor for the Han Dynasty.


Huo’s men crossed a valley north of the upper reaches of the Zhuanglang River and headed north through the Wuqing Mountains into the Hexi Corridor. Huo took this route, a shortcut from ancient times to the present, and it is almost the same way that the Lanxin Railway and Lianhuo Highway today enter the Hexi Corridor.


After the Han army crossed the Wushiling, the weather was new, coming to the source of the Gulang River, along which is the Hexi Corridor. The Gulang River flows into the Red Water River, and then into the Shiyang River and the Huetu River.


The nomadic group that occupies the Gulang River is the Nimibu, a branch of the Shubu clan, one of the four major Xiongnu clans, and since the Xiongnu occupied the Hexi Corridor, the old Shang Shan Yu made the Shubu clan split up a part of its people to guard the southern end of the Corridor, called the Nimibu clan.


The Nimble tribe is the second highest ranking tribe in the Hexi Corridor, with a population of tens of thousands, and has been associated with Shan Yu’s headquarters by marriage, and has provided a large number of war horses to the Xiongnu.


This battle saw the Han army defeat the enemy army, with less than a hundred dead and seriously wounded. The first time I saw this, I was able to get the head of the nimble Pu king, and I turned on my horse, and I couldn’t hide my joy anymore, as if the head of the nimble Pu king was not hanging by the horse’s belly, but a heavy marquis title. The company’s main goal is to provide the best possible service to its customers.


Nearly 10,000 Han Chinese horses’ hooves shook the sky and swept the valleys and rivers, and the Nim Pu tribe was never seen in the history books again.


When they came to the Shiyang River, they did not go north to find King Huutu, but crossed the river to the west. The first time I saw this, I was able to get to the top of the river.


The Huncian tribe did not expect the Han army to come from the direction of the Huutu tribe, and was defeated in a hasty battle. The Han army captured Prince Su of Huutu, the Sangha, the captain and other important people.


From the destruction of the Nimble Pu tribe to the defeat of the Hun Xie king, it took only six days for Huo to go. The Xiongnu surrendered pawns provided accurate intelligence for the Han army, and Huo went to the extent of starting a number of Xiongnu men as guides. Six days to break the five kingdoms, Huo dust a thousand miles surprised.


King Huo Tu and King Hun Xie each led 10,000 troops to block the Han army under Mount Haili. The mountain is located in the middle of the Hexi corridor, and if Huo went to defeat, it would certainly be a total loss of the army.


The battle was a disastrous victory for the Han army, with less than 3,000 survivors. The Xiongnu, on the other hand, were defeated, with King Zuolan and King Luhou killed and over six thousand killed in action.


When Huo returned to Jincheng, there were only 2,000 men left, and everyone was wounded, with only a few dozen war horses left. In the first battle of the Hexi Corridor, the Han army captured the Xiongnu sacrificial gold men, killed King Nimble Pu, King Zoran and King Lu Hou, beheaded more than 8,900 Xiongnu, and captured Prince Huotu, the Sangha and the captain.


In ancient times, Lanzhou was a must-see destination for the Central Plains to the Hexi Corridor and the Western Regions, and an important transit point on the Silk Road. Nowadays, with advanced transportation, Lanzhou’s position as a hub has not diminished, with the Longhai Railway and Lanzhou-Xinjiang Railway intersecting in Lanzhou.
