Jingbirok (A Record of Rebuke and Admonition) Book 4 — The Geunpok Collection A record left by Ryu Seong-ryong, Chief State Councillor, of what he saw with his own eyes after the Imjin War ended. Its title comes from the line, "I rebuke what is past, and take heed against troubles to come." He set down without excuse how the war began and what the court failed to do. His recommendation of Yi Sun-sin, the wrangling with the Ming army, and the suffering the people endured are all recorded as they were.
