A collected writings of crown prince Hyomyeong (1809-1830) who was a father of Heonjong and a crown prince of Sunjo, the 23rd king of Joseon. Hyomyeong’s name was Dae and penname was Gyeongheon. As his son Heonjong ascended the throne, he was given a posthumous name Ikjong. Ikjong had an excellent talent for writing and left many books such as 『Gyeongheonsicho』『Hakseokjip』, 『Damyeoheonsijip』, etc. There are two kinds of 『Gyeongjeonjip』 at Jangseogak but their contents are the same. Although the title and volume is ‘Gyeongheonjip’, in the middle is written ‘Damyeoheonjip’.
