What are the unique architectural methods and materials in Chaoshan area?

Chaoshan area still retains the ancient architectural style of plate building. Generally, the raw materials are mixed with red clay and crushed stone to build a wall, instead of using bricks that consume good soil in the field and then mixing silt and shell ash to paint the wall. Some of them are rammed earth or woven from wood and grass. Previously, the poor by the sea lived in huts called "thatched cottages", and stone materials were mostly used for doorframes, railings, drum stones, steps and column bases of building components. There are ceramic coping with flowers on the roof and ridge, which can not only ventilate, but also prevent wind. There are two (or three) layers of blue tiles. Seven meals on the upper floor and three meals on the lower floor, and then press the tile pipe to insulate the water between the two tiles.
