趙光祖
One of his sons was Song Yik-pil, who became a scholar of such renown that he formed friendship with Yi I and leading Westerners who praised that his achievement was enough to cover his father's crimes. It is remarkable indeed that Song Yik-pil overcame the fact that his father not only betrayed his master and benefactor, which would be considered one of the worst sins in Confucian world, but caused one of purges against the Sarim scholars, especially Jo Gwang-jo's supporters. By Seonjo's reign, the Sarim faction took control of the government and Jo Gwang-jo and Ahn family were fully rehabilitated as their martyrs.
