Fu-an Residence, also known as Tujiaocu, is an architect unique to Shenkeng. Warm in the winter and cool in the summer, this structure is known for its countryside fragrance . Tujiaocu refers to the square-shaped bricks made of clay, soil and cow manure mixed with paddy rice husks and stems. These dried bricks are as tough as red-tile bricks but they offer even better ventilation and drainage. There are still residents living in Fu-an Residence so visitors can only view the exterior.
