The original name of Nanjing Yunshui Ballad is Changjiao, where the mountains and rivers are beautiful and the humanities are rich. The long ancient road in the village, the century-old banyan tree, the magical earth building and the clear water of Lingshan all give people a sense of detachment. At the end of 2005, the film "Ballad" adapted from Zhang's film literary script "Searching" was filmed here. After the successful application for the heritage of Fujian Tulou, visitors can enjoy the grotesque architectural beauty, enjoy the long ancient roads and clear water, and feel the deep roots of exchanges between Fujian and Taiwan. After the successful application for the heritage of Fujian Tulou, the local government officially named this ancient road in the village, which is 10 km long and all paved with pebbles, as "Yunshuiyao Ancient Plank Road" and named Changjiao as "Yunshuiyao" ancient town. Nanjing? Tulou refers to tulou located in Nanjing, Hua 'an, Pinghe, Zhao 'an, Xiao Yun and Zhangpu mountainous areas of Zhangzhou City. It is famous for its long history, large quantity, large scale, strange shape and unique style, and is known as "the mythical mountain architecture".
Fujian tulou came into being in the Song Dynasty, matured gradually in the Ming and Qing Dynasties, and has continued 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.
