A hollow brick includes a bottom wall, two side walls projecting from the bottom wall, a plurality of intermediate walls projecting from the bottom wall between the side walls, and a top wall opposite to the bottom wall and connecting the side walls and the intermediate walls. A plurality of ventilation holes is bounded by the bottom wall, the side walls, the intermediate walls and the top wall. Each ventilation hole has two ventilation open ends opposite to each other along the transverse sides of the bottom wall. Two outer holding ribs projects respectively from outer surfaces of the side walls in opposite outward directions.
