Provincial rural reporting describes Zhenjiawan in Yanchuan County under Yan'an as the largest and most complete surviving ancient cave-dwelling complex in northern Shaanxi, with ninety-seven courtyards and two hundred fifty-eight caves still recorded. The numbers turn a hillside into a countable settlement fabric rather than a single scenic cave.

Stone rooms and courtyard walls
The same description reads the village through stone yaodong cut into the slope, stone courtyard walls, stone paths, date trees on the ridges and millstones in the corners. It is lived architecture assembled from loess-country materials—courtyard life without a flat plain—before any later film crews arrived.
