周仲尼謂季桓子曰。丘聞之。木石之怪夔蝄蜽（韋昭注曰。木石謂山也。蘷一足越人謂之山魈。或言獨足。蝄蜽山精。好學人聲。而迷惑人也）右出國語。史記曰。秦始皇云。山鬼不過知一歲事也。

In the Zhou dynasty, Zhongni said to Ji Huanzi: 'I have heard that the anomalies of wood and stone are the kui and the wangliang.' (Wei Zhao's commentary says: 'Wood and stone refers to mountains. The kui has one foot; the people of Yue call it the mountain xiao, or say it is single-footed. The wangliang is a mountain spirit that likes to mimic human voices and delude people.') The above is from the Guoyu. The Shiji states: First Emperor of Qin said, 'Mountain ghosts know nothing beyond the events of a single year.'
