Technically, non-Chinese are forbidden from sleeping in the village and are required to stay at the government run hotel outside the village.
A much better option is to wander around the village with your backpack on, perhaps around the south lake, and wait for some friendly local to furtively usher you into their home. Quickly they will offer you to stay in one of their clean doubles for around ¥80-¥100 per night. Air-conditioning is provided in the winter but you may have to pay extra. They may ask you to stay only one night and find another friendly local tomorrow.
