Shanzhou Underground Courtyard

Shanzhou Underground Courtyard is worth a visit. You see trees but not the village, enter the village but not the houses, go inside but not see doors, only people. The Sanmenxia Underground Courtyard, also known as the Skywell Courtyard, is a remnant of the ancient human dwelling lifestyle, known as the 'underground quadrangle' of northern China, with a history of about 4000 years.
