Lanzhou, the capital of Gansu province, is not only the political, economic and cultural center but also the center of the northwest in terms of transportation and telecommunication.
Lanzhou, known as the Yellow River and the Silk Road, used to be a key point on the ancient Silk Road and played an important role in cultural exchanges between East and West, and besides, it is the only capital city where the Yellow River runs through from the west to east. Lanzhou is surrounded by hills overlooking the river to form a unique and beautiful urban landscape.
