Introduction to seaweed houses: Seaweed houses are one of the most representative ecological dwellings in the world. They are mainly distributed in Weihai, Qingdao, Yantai and other coastal areas of the Jiaodong Peninsula in my country, especially in the Rongcheng area. Because Rongcheng is located along the coast, summers are humid and winters are extremely cold. In order to avoid rain and keep warm, residents built thick stone walls and dried seaweed as a roofing material to build this unique style of seaweed house.
