In the early days of founding the Gyujanggak(奎章閣) Archives, King Jeongjo established the Bul’un-jeong(拂雲亭) pavilion, which served as a place for archery and a space in which governmental personnel could be trained in both literary and martial arts. Jeongjo ordered the manufacturing of target boards, modeled after the Guhu-beob(九帿法) methods that had earlier been suggested by the Chinese Song(宋) dynasty’s Sīmǎ Guāng(司馬光), and enjoyed archery himself with his close associates. Also, inspired by the Chinese Ju(周) dynasty and its institutions, he renamed these archery sessions to Yeonsa-rye(燕射禮), which referred to archery sessions performed at the Yeonchim(燕寢) chamber, the king’s most private space, and made it a ritualistic occasion.BR In 1779, 3SUPrd/SUP year of King Jeongjo’s reign, the Yeonsa-rye ritual was performed at Bul’un-jeong for the very first time. And later in 1783, Jeongjo’s 7SUPth/SUP year, a practice session(習儀) for Yeonsa-rye was held at the Chundang-dae(春塘臺) tower. At this occasion, Jeongjo added the protocol of ‘Yeon’eum(燕飮, drinking at Yeonchim)’ to the Yeonsa-rye protocols(儀註), upgrading it to “Yeonchim Eumsa-rye Euiju(燕寢飮射禮儀註).” This modification was due to Jeongjo’s will to consolidate his own relationship with closest aids, including the Gyujanggak officials[閣臣].BR As we can see, the Joseon dynasty’s Yeonsa-rye ritual was formalized by King Jeongjo’s determination to establish an amicable atmosphere between the king and the vassals, and a steadfast environment in which the king could encourage everyone to train themselves in both literary and martial capabilities, through regular archery sessions conducted in the king’s most private place. What should be noted is his idea to elevate the act of archery with his close associates to the level of rituals and protocols(禮), and his efforts to modify the old protocols(古禮) to match the time and his own intentions. It shows us that Jeongjo tried to put official protocols to a good use to the best of his abilities, and create an institution
