Hwang Hui was once banished from Seoul because he advocated Yangnyeong, the eldest prince of King Taejong, despite his bad behavior in 1418.
After King Sejong the Great's enthronement, Hwang Hui got reappointed and held many ministerial posts.
He distributed grain seeds for improving farming, and ordered each province to plant a lot of mulberry trees to enrich human life.
And in an effort to obtain a wide range of good manners, the etiquette of Goryeo was revised and supplemented, taking into account the reality of the Ming and Joseon dynasties.
Priorities during his administration included agricultural improvement, mitigating laws that increased social class gaps, and providing opportunities for candidates born out of wedlock or from concubines to take the civil service examination.
