On 27 December 2009, the Henan Provincial Cultural Heritage Bureau reported the discovery of Cao Cao's tomb in Xigaoxue Village, Anyang County, Henan. The tomb, covering an area of 740 square metres, was discovered in December 2008 when workers at a nearby kiln were digging for mud to make bricks. Its discovery was not reported and the local authorities knew of it only when they seized a stone tablet carrying the inscription 'King Wu of Wei' — Cao Cao's posthumous title — from grave Robbers who claimed to have stolen it from the tomb. Over the following year, archaeologists recovered more than 250 relics from the tomb. The remains of three persons — a man in his 60s, a woman in her 50s and another woman in her 20s — were also unearthed and are believed to be those of Cao Cao, one of his wives, and a servant.
