Sitting midway between Yǒngdìng and Nánjìng, this four-storey building is a huge roundhouse with inner concentric passages, tiled interior passages and a courtyard. It also sports a huíyīnbì (回音壁) – a wall that echoes and resonates to sharp sounds. Some villagers may ask you for a ‘sanitation fee’. It’s not legal. Don’t pay.
