The Mulan Pond is located at the foot of Mulan Mountain in Pitou Village, five kilometers south of Putian City, Fujian Province.
The Mulan Pond was one of the largest irrigation works in ancient China. The project has a weir-sluiced dam that is 219.3 meters long and 7.5 meters high, and built on 33 piers with 32 sluices. A 500-meter-long bank lies on both ends of the dam. Water is channeled from the pond into large and small canals with a combined length of 120 kilometers to irrigate the southern and northern plains of Putian. Water is then discharged at 300 points along the way before joining the Xinghua Bay.
Built in 1075 during the Northern Song Dynasty (960-1127), the Mulan Pond has turned 10,000 qing (1 qing = 6.6667 hectares) of land into fertile soil, promoting the economic development of Putian.
To honor the four ancestors who built the pond , people of later generations erected Mulan Pond Memorial Hall. The hall houses statues of the pioneers alongside a number of stone tablets with inscriptions by famous scholars of the Ming Dynasty (1368-1644). After the founding of new China, the irrigation area was expanded from 15,000 to 25,000 mu (1 mu = 1/15 of a hectare).
