The reason for the small cave window

The reason why the hole window is small is to ensure that there is less dust blown into the hole.

According to relevant data, in the northwest of northern Shaanxi, the wind blows from Sha Fei. In order to ensure that there is less dust blown into the cave, the doors and windows of the local people are particularly small. Although it blocks a lot of light, it also shows local characteristics due to environmental restrictions. They are also quite comfortable in this cave with small doors and windows that are almost isolated from the outside world.

Cave dwelling is a unique residential form on the Loess Plateau in northern China, with a strong China folk custom and local flavor.
