official. But the tanner repeatedly refused Jo's offer and then disappeared without a trace according to Records of Yeonryeoshil (연려실기술), a collection of official and unofficial history books compiled by Yi Geung-ik in late Joseon Dynasty. (It is said that King Injong, Jungjong's successor who admired his tutor Jo Gwangjo, listed the "tanner" as Chief State Councillor for his future cabinet for he was greatly admired by Jo.) According to famous Korean philosopher Yi I, Jo was admired so much by populace that when he appeared on streets people gathered before him saying, "Our master is coming." Sarim's Power Base Jo Gwangjo's radical reforms were popular with the populace, who called him the "living Buddha", but he faced fierce opposition and hostility from the Hungu faction. In early 1519, several Hungu officials began a plot to assassinate Sarim officials, though they were discovered in time. Jo's power base was concentrated in four offices: Inspector General's Office (사헌부; whose main function was to impeach corrupt or unprincipled government officials in court and local administration), Office of Censors (사간원; whose role was to criticize wrong policies of the king or ministers), Hongmoongwan (홍문관; an advisory council that answered the king's questions and educated the king with history and Confucian philosophy), and Royal Secretariat (승정원; which served as liaison between the king and ministries). The first three offices were collectively called Three Offices, or Samsa (삼사), as they provided checks and balance on the power of the king and the ministers and also served as organ of press that influenced general opinion of the court. However, the Sarim faction did not control any army nor had financial base. Sarim's power was solely dependent on the king's support, which Jo believed to be steadfast in their mutual pursuit of reforms. However, Jo's unbending character and his frequent remonstrations to Jungjong to support his radical programs began to irritate the king. Even when he disagreed with Jo, Jungjong almost always ended up adopting Jo's petition because Jo would refuse to bend his will and Three Offices would threaten to resign en masse. Furthermore, Jo and Hongmoongwan officials often instructed Jungjong on the ways of king in long lessons. Because Jungjong was not a crown prince, he had not received a thorough royal education expected of future king, and Sarim scholars sought to rectify this, believing that only learning could prevent a despot like Yeonsangun.
