Located in Huzhou, Zhejiang Province, Digang Village has earned a spot on UN Tourism's 2025 list of Best Tourism Villages. Here, an ancient ecosystem thrives in harmony. Mulberry trees grow along the banks of ponds. Their leaves feed silkworms, and the silkworm waste nourishes the fish. The fish then excrete into the ponds, fertilizing the mulberry trees and sustaining the cycle.

This self-sustaining cycle, known as the Mulberry-Dyke Fish Pond System, is recognized as a globally important agricultural heritage system. For generations, villagers have preserved the traditional crafts of mulberry cultivation, silkworm rearing, and silk reeling – practices that form the foundation of China's intangible cultural heritage of sericulture and silk weaving, which gave rise to some of the earliest silk fabrics in Chinese history.
