The ancient village of Yijiawan is located 15 kilometers northwest of Yanchuan County. The existing ancient cave dwelling was built before the Yuan Dynasty five years (1265) and has a history of at least 752 years. Before the reign of Emperor Kangxi in the eleventh year (1702), the surname of He moved out of the surname and moved to the name of the village. Here is a real ancient village. The traces of the years are clearly visible. The feelings of people sometimes returning to the light are very indifferent. The rows of cave dwellings carry the warmth of the past and the hope of giving birth. When the high-rise buildings made of reinforced concrete gradually replaced the independent and free farm life, the village of North Shaanxi, which has the most primitive features, is quietly bathed in its unique sunshine. Stone mills, wooden doors, earthen urns, stone walls, as if everything was yesterday.
