2. Fujian Tulou was born in the Song Dynasty, matured in the Ming and Qing Dynasties, and continues to this day. Fujian Tulou is a unique large-scale rammed earth residential building in mountainous areas in the world. It is a self-contained, economical, solid and highly defensive high-rise building model, which absorbs the "Feng Shui" concept of traditional architectural planning in China, adapts to the living and defense requirements of co-living, and skillfully uses the narrow flat land in the mountains and local raw soil, wood, pebbles and other building materials. The building materials of Fujian Tulou are very strange, which are composed of clay, glutinous rice, brown sugar, bamboo chips and water. The completed earth building is warm in winter and cool in summer, and has strong typhoon resistance and earthquake resistance. It used to be the shooting place of the third stop of Hunan Satellite TV's "Where is Dad Going for the Third Season" and the shooting place of CCTV Spring Festival Evening public service advertisement "Dreams shine into my hometown".
