"The Yellow River in the world nine curves and eighteen bends, the most beautiful is the first bend!" Yellow River as the mother river of the Chinese nation, many places call their own Yellow River the first bend, in fact, the closest to the source of the Yellow River "the first bend of the Yellow River", is in Gannan Prefecture, Gansu Maqu County. Maqu, the translation of the Tibetan "Yellow River", is also the only county in the country named after the mother river of the Chinese nation. The reason why Maqu County has the reputation of "the first bend of the Yellow River in the world" is because the Yellow River originates from Qinghai Bayan Kala Mountain, enters the territory of Maqu County east, and then returns to Qinghai Province northwest along the Animaqing Mountain and Xiqing Mountain. The entire Panhuan route is 433 kilometers long. The prestigious "first bend of the Yellow River in the world" has been formed, because this bend is too big, people can hardly feel its existence. Maqu County occupies the first song of the Yellow River Jiuqu, the water resources are very rich, and the Yellow River section in the country is also flowing rapidly. For thousands of years, the only way people want to cross the river is to swim with their horse tails, so there is little communication between the people along the river, and even the customs are very different. In April 1976, the Maqu Yellow River Highway Bridge opened 4 kilometers away from the county seat. In 1979, the "Maqu Yellow River Bridge" was completed and opened to traffic. The bridge is a reinforced concrete arch bridge, with a total length of 280 meters, a width of 7.5 meters, a main span of 3 holes, a span of 70 meters, and a net height of the lowest string under the bridge. Although the bridge does not look as grand as some of the bridges downstream of the Yellow River, it is the first bridge built in Maqu on the upper reaches of the Yellow River, and is therefore also known as the "First Bridge of the Yellow River". It is worth mentioning that the "Maqu Yellow River Bridge" was built in the high-altitude oxygen-deficient permafrost, which was an extraordinary feat at the time. It is understood that the volume of frozen frozen soil will expand in the cold season, and the bridge base built on it will be raised by the "fat" frozen soil. In summer, the volume of the melted frozen soil will shrink, and the bridge base will be concave. This situation will alternate with the freezing and melting of the frozen soil. Standing on the Maqu Yellow River Bridge overlooking the mother river, the yellow turbid river flows from east to west, like a smooth drifting belt slipping between the world. On the Maqu grassland on both sides of the river, cattle and sheep are flocked, snow-capped mountains and lakes are intersected, and the Maqu County in the distance is vaguely visible. Faced with this fairyland-like place, passers-by will stop and watch and appreciate the gift of nature. Maqu Yellow River Bridge and two beautiful landscapes should not be missed: First, "arch bridge day", standing on the left side of the bridge in the early morning, you can see the east red sun rising, when the red sun rises to the bridge, just like the arch bridge to lift a red sun. Second, the "long river sunset", at sunset standing on the bridge looking at the rolling Yellow River, the sunset sinks, just like falling into the long river, the scene is quite spectacular. According to legend, Maqu is also the hometown of King Gesar. In the majestic wood road of Gesar's birthplace, 4 kilometers west of the bridge, visitors can enjoy the magnificent landscape of the Yellow River falling from the sky. More than 10 kilometers northeast of the county seat, tourists can also see the whole picture of the small song similar to the whole picture of the first song, which is pleasing to the eye and breathtaking.
