The streets of Qinghai are full of modern buildings. Through these surfaces, we can still feel some national characteristics. In terms of color, Tibetans use checkers with black background, yellow and red. In terms of architectural style, we can see the style of China culture brought by Princess Wencheng when she entered Tibet. Hui nationality is represented by green halal sign. There are Mongolian yurts and brick houses that like to maintain national characteristics, and there are other Tujia Dongxiang people. You can only see it by careful observation.
