The Yellow River feeds the south of the Yangtze River. "Orchards under Helan Mountain are formed, and Jiangbei is old and famous". The unique local environment in Ningxia Plain makes the products here rich and unique. Among the five treasures represented by Lycium barbarum, licorice, Helan stone, beach sheepskin and Nostoc flagelliforme in Ningxia, both Lycium barbarum and beach sheepskin are produced in Ningxia Plain. In addition, the specialties such as red melon seeds and golden crown apples here are also famous for a long time. Here is an oasis in the vast tidal sea, and it is a legend that has been interpreted under Helan Mountain for more than 1000 years. With the nourishment of the Yellow River, it has become the south of the Yangtze River in the northwest, a water town in arid areas and a granary in the northwest. In this beautiful and rich land, the simple folk customs have not changed so far, and the idyllic lifestyle is particularly desirable. This is the Ningxia Plain where "the Yellow River is full of disasters, but only one episode is rich", and a song called "Jinchuan Yinchuan Miliangchuan" has been sung for thousands of years. Ningxia, Huang Hefu is a typical oasis in the world, and Ningxia Plain has enjoyed the reputation of "Water Town in the South of the Yangtze River" for over 1000 years. Yinchuan Plain, located in the arid area, has an annual precipitation of 2000 mm, and such water conditions can't meet the growth of crops at all. However, because of the appearance of the Yellow River, there is a saying that "Ningxia is the Huang Hefu of the world". People on the Ningxia Plain can see this blessing from the Yellow River in this folk song: "Ningxia Chuan, with two sharp ends, borders the Yellow River in the east, Helan Mountain in the west, Jinchuan Yinchuan Miliangchuan." The large area of green in Yinchuan Plain is directly related to the gift of the Yellow River. The annual runoff of the Yellow River is 30.7 billion cubic meters, accounting for more than half of the whole river. The Yellow River has become a rich river and a rich river here. The Yellow River flows through Ningxia for more than 390 kilometers, forming Ningxia Plain, which consists of Weining Plain and Yinchuan Plain. The water conservancy projects at the mouth of the Yellow River formed by gravity flow contain the wisdom of generations of water conservancy project designers since Qin Dynasty. After Qin Shihuang destroyed the six countries, it became a big problem to build a county in Hetao area, set up fences and open the border for immigrants. Opening canals for irrigation and developing agriculture in Ningxia plain became a national event involving the stability of the northern part of the Qin empire at that time, so the Qin Canal appeared and began the history of irrigation from the Yellow River in Ningxia. During the reign of Emperor Wu of the Han Dynasty, he made several missions to Ningxia, and hundreds of thousands of immigrants developed Ningxia Plain. At that time, the Han Canal was dug. The opening of the Han Canal triggered the climax of national water conservancy construction in the period of Emperor Wu of the Han Dynasty, mainly concentrated in the Yellow River basin. Tanglai Canal is the most famous canal in Ningxia Plain today, which was expanded in the Tang Dynasty. Total length155km, more than 500 channels, irrigation1140mu, ranking first among Ningxia Plain14 Grand Canal. After the Anshi Rebellion broke out in the Tang Dynasty, Emperor Xuanzong of the Tang Dynasty fled to Sichuan in a hurry. Persuaded by some wise ministers, Prince Hengli chose Lingzhou (now Lingwu area) on Ningxia Plain to reign. The abundant grain and grass in Ningxia Plain not only met the needs of the troops stationed or mobilized here at that time to revive the Tang Dynasty, but also met the munitions of the Pingding rebellion in the late Tang Dynasty. Ningxia Plain became a huge source of nutrition for the reconstruction of the Tang Dynasty. Because Ningxia Plain is in the buffer zone between the farming culture in the Central Plains and the nomadic civilization in the north, those species from the Central Plains or the western countries began to take root and sprout on this fertile soil on a large scale. By the end of the Tang Dynasty, the channels built on the Ningxia Plain during the Qin, Han and Tang Dynasties were gradually improved, and the fruits and vegetables on the Ningxia Plain with the three Grand Canal turned into forests. Wei Chan, a poet at that time, wrote in his "Send Luban Shangshu to Lingzhou" that "the orchard under Helan Mountain became. This is the earliest origin of the "blockade of Jiangnan" that people in Ningxia Plain often take pride in later. The north is the south of the Yangtze River, Yinchuan, which is known as the land of plenty.

In the vast golden ocean of the northwest loess plateau, a vast green island miraculously appears, which is the rich and beautiful Ningnanchuan on the Cezanne River. In the middle of this green island. There is a picturesque city, that is Yinchuan, the capital of Ningxia Hui Autonomous Region and the famous ancient city Cezanne.

The land in Yinchuan Plain is fertile. Rich in natural resources, it has been known as "Jiangnan" and "Land of Fish and Rice" since ancient times. The city covers a total area of 4,467 square kilometers, of which the urban area is 1.457 square kilometers, and it governs urban areas, new urban areas, suburbs and Yongning County. The total population is 760 thousand. Today, Yinchuan has developed into a new industrial city. Ningxia specialty beach wool blankets produced by Yinchuan Wool Mill are exported to more than 20 countries in Asia, Africa, Europe and America. The antique carpets produced in Yinchuan are antique and belong to the first-class treasures.

"Without Helan Mountain, there would be no Ningxia Chuan". In folklore, Helan Mountain was originally a fine horse running from afar, resting by the river and turning into a high mountain; The Yellow River is a dragon. It rushed in and roared away, only making a gentle long chant in Ningxia River. Yinchuan is located between Malone and Malone, covering an area of more than 4,000 square kilometers, connecting Lanzhou, Gansu in the south and Baotou, Inner Mongolia in the northeast, all over 400 kilometers. Baotou-lanzhou railway connected them together. Helan Mountain is in the northeast direction, located at the western border of Yinchuan, with a length of 70 kilometers, accounting for about 46% of the total length of Helan Mountain. The height of the main peak is about 2500 meters. Seen from the west of Yinchuan Plain, Helan Mountain is like a galloping horse, which is the dividing line between monsoon climate and non-monsoon climate in China. It blocks the eastward movement of Tengger Desert, weakens the invasion of northwest cold current and sandstorm, and is a natural barrier of Yinchuan Plain, which makes the blue sky here clear.

Yinchuan belongs to the temperate arid climate zone, with four distinct seasons, long cold in winter but not extremely cold, short hot in summer without intense heat. Yinchuan has long sunshine time, strong solar radiation and large temperature difference between day and night, which is beneficial to the growth of crops. Therefore, the agricultural products such as wheat, rice, beets, vegetables, melons and fruits produced here have high sugar content and protein content, rich nutrition and excellent quality.

Yinchuan is an ancient city with a long history. As early as four or five thousand years ago, there were human activities in the Paleolithic Age. Historically, it was once a nomadic place for Rong Di and Xiongnu. The Qin Dynasty belonged to the northern territory of Beidi County. Until the Xia Dynasty in the fifth century, the "Drinking Seoul" was built about 8 kilometers east of Yinchuan today. It used to be the royal garden of Helian Bobo's Daxia regime, named Lizi Garden, and it is a amusement city. Yinchuan was founded in 678 AD (three years in Yifeng, Tang Gaozong), with a history of 1300 years. In A.D. 1038, Li Yuanhao, the leader of the Tangut, founded the country here and proclaimed himself emperor, which was called "Xixia Kingdom" in history, and Yinchuan was called Xingqing House.

The long history has left Yinchuan with rich regional cultural landscape and humanistic tourism resources. There are more than 60 scenic spots and natural scenic spots in China, especially the Xixia Mausoleum, a national key scenic spot, and the ancient carved rock paintings of Helan Mountain, which have attracted the attention of scholars and tourists at home and abroad. Zhang Xianliang, a famous writer, founded Zhenbeibao Huaxia Western Film and Television City, which made China films go to the world from here because of filming Red Sorghum and other films. There is also a national nature reserve in Helan Mountain-Suyukou National Forest Park. The natural scenery in the south of the Yangtze River, the customs of Hui Muslims and Xixia culture constitute Yinchuan's new tourism industry, which is characterized by "Xixia ancient capital and frontier customs". Now, Yinchuan is one of 99 famous historical and cultural cities in China, and it is also one of the most attractive and potential tourist cities at the intersection of Hetao culture and Silk Road culture in China.
