英文摘要	Fangzhu, which has been lost for thousands of years, is an ancient device for water collection from air; its mechanism is unknown yet. Here we elucidate its possible surface-geometric and related physical properties by the oldest theYin-Yangcontradiction. In view of modern nanotechnology, we reveal that Fangzhu's water-harvesting ability is obtained through a hydrophilic-hydrophobic hierarchy of the surface, mimicking spider web's water collection, lotus, or desert beetle's water intake. The convex-concave hierarchy of Fangzhu's textured surface enables it to have low wettability (high geometric potential) to attract water molecules from air through the nanoscale convex surface and transfer the attracted water along the concave surface to the collector. A mathematical model is established to reveal three main factors affecting its effectiveness, i.e., the air velocity, the surface temperature, and surface structure. The lost technology can play an extremely important role in modern architecture, ocean engineering, transportation, and others to catch water from air for everyday use.
