王導
A native of Wenxi County, in what is now southwest Shanxi Province, Guo studied Daoist occultism and prognostication in his youth, and mainly worked as a prognosticator for various local officials and leaders, interpreting omens and portents in order to predict the success or failure of various endeavors. In AD 307 a Xiongnu clan invaded the area and Guo's family relocated south of the Yangtze River, reaching Xuancheng and eventually settling in Jiankang (modern Nanjing). Guo served as an omen-interpreter to military leaders and Eastern Jin chancellor Wang Dao before being appointed to official court positions in 318 and 320. Guo's mother died in 322, which caused Guo to resign his position and spend a year in mourning. In 323 Guo joined the staff of warlord Wang Dun, who controlled much of the modern Hunan and Hubei areas, but was executed in 324 after he failed to produce a favorable omen toward Wang's planned usurpation of the Eastern Jin throne.
