新五代史
Lu Wenjin () (died 944), courtesy name Guoyong () (per the "History of the Five Dynasties") or Dayong () (per the "New History of the Five Dynasties"), formally the Prince of Fanyang (), was a general of the Chinese Five Dynasties and Ten Kingdoms Period states Yan, Jin, Jin's successor state Later Tang, Wu, and Wu's successor state Southern Tang, as well as the Khitan Empire. He had, early in his career, defected to Khitan and was instrumental in building Khitan's strategies of periodic incursions into Chinese territory, but later redefected to Later Tang. When Later Tang was overthrown by the Khitan-supported Later Jin, Lu, in fear, fled to Wu, and remained at Wu and then Southern Tang for the rest of his life.
