Walls

Skillful construction workers use glutinous rice paste mending together clay or black bricks to build walls in China.
Clay bricks are used for folk houses while black bricks are used in many ancestral halls, study halls, temples and large
mansions. The main behind is black bricks are more costly to make. The production involves several burning
procedures inside an urn. Only very fine sand can yield this kind of bricks.

On both sides of the building we find gable walls. They are usually in the shape of the handles of

a wok or pyramids. The latter is more common in Hong Kong.

The front wall is known as the front eave wall while the one at the back is
the back eave wall.

Due to the lack of drainage system in the buildings, residents always suffered from flooding. Therefore, the walls are
uplifted with granite so as to be protected from the water. Doorsills are designed to prevent water from flowing inside
the buildings.

Moreover, window is not a regular feature in Chinese architecture since it is believed to be a way for the fortune to leak.

Grille-tiles, in the shapes of ancient coins and bats are fitted onto walls to enhance ventilation

and the illumination.
