The Moon Pond, named "Moon Pool" by the civilians, was firstly built from 1403 to 1424 (the Yongle Period of Ming Dynasty). At that time there was a man named Wang Siqi, who, after discovering a natural fountain in the village, gushing ceaselessly in winter and the spring, invited for three times a geomancer, He Keda, in Haiyang county (today's Xiuning), together with able persons in his own tribe, to investigate the mountains and rivers all around, and formulate a blue print in extending the basic site of Hongcun, programming the whole village with this "bull-shaped" water system. The project was meant to guide water from the western brook around the residence, with the curving ditch as the "bull intestine"; water was also to be guided into the village center to build the Moon Pond, in order to store up water for drinking and fire fighting. A follow-up investment was made by his descendant Wang Shengping, with the continuous working upon the ditch and the lune pond. Finally the Moon Pond was completed, with its green water all year round, its mirror-like surface, the bluestones spread in its neighbourhood, pinkish walls and black tiles orderly rowing on its sides, and the blue sky and milky cloud reflecting in it. The old people always have a chat among themselves beside the pond; together with them are the washing women, and the frolic children.
