What are the traditional cultural elements in Gansu, such as flying in Dunhuang?

Gansu is of course the Dunhuang Grottoes.

The flying sky you mentioned is just a famous element in the grotto murals, and there are many "inverted pipa" sculptures.

Yun (musical instrument), the musical instruments there are somewhat similar to those of the Han nationality, but the operation is far from it.

Because Gansu belonged to the Western Regions in ancient times, there are also many legends and stories there. It is also on the Silk Road.

Many buildings of the Tang Dynasty were left behind. It is very different from the local buildings.

Most of the buildings in the western regions are earth structures, while most of the buildings in the Tang Dynasty are wood structures.

And the Loulan culture there. You can still see the ruins of Loulan. Although it is unrecognizable, the building structure is perfect.
