Villagers are the descendents of ethnic Han soldiers originally from south of the Yangtze River, including Jiangsu and Anhui provinces.
Their dialect, attire, diet and customs have changed little over the centuries.
Benzhai village is one of the best-preserved settlements.
Elderly women wear their hair in buns beneath headscarves and silver adornments. They wear blue dresses with large sleeves and intricate patterns on the collars and cuffs.
The village's arched gate was closed at night in the past. A small emergency exit, only large enough for one person to pass through at a time, has since been sealed with bricks.
Benzhai is densely packed with interconnected courtyards and houses with attics, and nine watchtowers with slots for shooting arrows at enemies below.
