王延政
Yang Sigong () (died 945), nicknamed Skinner Yang (楊剝皮, "Yang Baopi"), was an official of the Chinese Five Dynasties and Ten Kingdoms Period state Min and Min's branch state Yin. He became a trusted official during the reign of Yin's only emperor (later Min's emperor as well) Wang Yanzheng and became known for harsh taxes against the people, leading to the people turning against Wang Yanzheng and welcoming an invading Southern Tang army, leading to Min's fall.
