Pei Ju

Pei Ju (547 – 3 October 627), birth name Pei Shiju, courtesy name Hongda, formally Duke Jing of Anyi, was a Chinese cartographer, diplomat, politician, and writer who lived in the Sui and Tang dynasties, briefly serving as a chancellor during the reign of Emperor Gaozu of Tang. He was praised by traditional Chinese historians for his ability and lack of corruption, but blamed for flattering Emperor Yang of Sui and practically directly contributing to Sui's downfall by encouraging many external military campaigns that drained Sui's resources. Modern historians have questioned these assessments: Arthur F. Wright labelled the latter judgement in the Zizhi tongjian a "particularly blatant piece of editorializing" and "absurd ... beyond doubt."
