Introduction to seaweed house: Seaweed house is a unique type of dwelling along the coast of Jiaodong. From a distance, the roof is covered with thick seaweed, which looks like a felt hat worn by an old man. The gray-yellow roofs and stone walls also bear witness to the life and historical changes of the island's fishermen. The seaweed house is warm in winter and cool in summer, comfortable and pleasant. Because the seaside air is humid, the seaweed made from local materials is both environmentally friendly and practical. It can not only block wind and rain, but also resist the erosion of sea water. It is said that it can live for hundreds of years without deterioration.
