Story:
During the Northern Song Dynasty, Wu Shi, the county magistrate of Zheng County in Huazhou, was profoundly learned and handled affairs with great flexibility.
His proposal of "moving troops to where food is" saved the imperial court a vast amount of manpower and resources. He frequently submitted memorials to Emperor Huizong, offering many reasonable suggestions.
Later, he was transferred to the capital to serve as an official. After interacting with him, the people from the Imperial Academy (Guozijian) all recognized his extensive knowledge and revered him as a 'Lìdì Shūchú' (a walking encyclopedia).
