Cars whiz past Tiaoshi in New Taipei City’s Jinshan District, on the coastal highway linking Jinshan with Danshui. Beside the road, a desert-colored, anthill-shaped home draws the eye. Viewed from above, the unusual structure looks a bit like a sea turtle crouched near the shore. Neither cafe nor B&B, owner Hoch Ho calls the home “dugu wu” (“dugu house”).
