Salim played active parts in the first half of 16th century in Chosun Dynasty. By the way, Chungju is meaningful, in that Salim had their bases more and more in Chunju. People who had been damaged from Kimyosawha under the 14th year of Jungjong dominion, gathered in Chungju. We might call those people Chungju Salim, for instance, Lee Yeonkyoung, Lee Yakbing, Lee Ja, Kim Sepil, Pak Sang, etc., They discussed about advanced studies of China, getting ready for a new period. Two of them were typical of Chungju Salim, who gained similar reputations. They had to retire to their native place, Chungju, after Kimyosawha, but their lives after that were different.
Lee Yeonkyoung lived a retired life in quiet. Nonetheless, his disciples started to play leading parts in the politics of Salim.
However, Lee Yakbing was unwilling to resign from major politics. As a result, he was caught up in political events.
Furthermore, his son and all of his disciples were caught up in 'ChunjuOk(충주옥)' and were damaged. 'ChungjuOk' was an event which Soyun(소윤) set up to eliminate Dayun(대윤).
The damage was so severe that Chungju became nearly empty.
However, people who had been damaged proved to be innocent right after Seonjo's(선조) accession to the throne.
Furthermore, as the politics of Salim opened up, Chungju Salim was revaluated.
