This is a book about the forms of etiquette to be observed by civilian officials, military officers, and persons appointed as officials by dint of the exploits of their ancestors. Distributed in 1866 (the 3rd year of King Gojong’s reign), it contains calligraphies by King Gojong and the request made by Heungseon Daewongun, the biological father of the king, that officials should respect each other.
