Lanzhou is a city with a long history and was founded around 5,000 years ago, the residents of Lanzhou created the “Majiayao Culture,” which is based on coloured pottery. As Lanzhou is in an area where the Han from central China merge with ethnic groups from the northwest, different cultures have been in coexistence since ancient times. Here in the city, rafts, pontoons, and water wheels represent Han culture, while mosques and religious education represent Muslim culture and the city was once a key point on the Silk Road.
