This article investigates works by Han-Yu and Liu Tsung-yüan to discuss how scholars keep their Confucian thought and take the responsibility of moralization when they were banished to the South. To begin with people’s image of South in Sui and Tang dynasties, we could find that North people all feared South deeply. When Han-Yu and Liu Tsung-yüan were banished to South, their actual experiences also reflected on those poetry and essays. Second, although Han-Yu has had friendly relationships with monks; however, his purpose is trying to guide those monks to resume secular life. While Han-Yu was taking up the position of the prefect of Chaozhou, he participated local affairs and liberated slaves. His activity is not only taking the obligation of scholars but also representing Confucian moralization. Third, as the subprefect of Yongzhou, Liu Tsung-yüan was still not to give up Confucian faith: settle down people. So he tried to request those powerful people to help him leave Yongzhou. Unfortunately, until he had been banished to Liuzhou, Liu Tsung-yüa just got a chance to practice Confucian moralization.
