As the capital of Gansu Province and the central city in the northwest region, Lanzhou's transportation status is very important: it reaches Dunhuang in the north, Gannan in the south, Xining in the west, and Yinchuan in the east. It can be said that it is a must-stop for traveling to the west. The Yellow River flows endlessly through Lanzhou from west to east, sandwiching it between the north and south mountains, making it a long and narrow city extending from east to west. As far as tourist attractions are concerned, the most prominent one is the "Hundred-mile Yellow River Style Line" along the Yellow River: Zhongshan Bridge, Waterwheel Park, the Statue of Mother Yellow River, and the night view of Baita Mountain are all scenes that cannot be missed when visiting Lanzhou . Day and night, the Yellow River water flows endlessly into the distance, making Lanzhou a city with "character". The rolling turbid waves and bursts of waves not only nourish the land and water of Lanzhou, but also create the generous and generous spirit of Lanzhou people. With a rugged character, this city also becomes warmer and richer because of the Yellow River.
