What material is the house in Lingnan?

Blue bricks, stone pillars and slates are the main ones. Guangfu dwellings are mainly distributed in the Greater Pearl River Delta, and the early Guangfu dwellings were obviously influenced by the architectural pattern in the south of the Yangtze River. Its representative is the bell house, which is made of blue bricks, stone pillars and slates, and the outer walls are decorated with flowers and birds. Because its gable is shaped like a bell, it is called a bell house.
