Zhong You (542–480 BC), commonly known by his courtesy names Zilu and Jilu, was one of the best known and most faithful disciples of Confucius. Among Confucius's disciples, he was the second in terms of ability and accomplishment in statesmanship, after Ran Qiu. He was noted for his valour and sense of justice, but Confucius often warned him against acting without forethought. He was killed in the State of Wey in defence of his lord Kong Kui.
