Above the Xiashui village, 16km outside of Guiyang, is a gigantic buddha statue, overseeing the Shalao river and the valley below. The statue was carved to ward off evil spirits lurking in the waters, so the buddha protects the surrounding farm lands from flooding.
The incomplete, 50-meters-high, statue was supposedly carved by Haineng (whose apprentice, Haitong, started the construction, at Leshan, of a similar giant statue of Maitreya, the future buddha). From the late Tang period (hence around 700–800 CE).
