Sancha Pond was built during the reign of Qing Emperor Jiaqing (in about 1860 AD) using hand-picked soil by the local Chen family. It is named "Three Forks" as it combines upstream rivers from three valleys. Sancha Pond covers an area of about two hectares and irrigates 100 hectares of fertile fields. In 2019, the government subsidized irrigation work to protect the slope with pre-casted stacked ecological blocks and reconstruct the local natural ecological environment, to breathe new life into the century-old irrigation pond.
