The Joseon envoy Yi Min-seong (李民宬), who traveled to Ming China in the third year of the Tianqi reign (1623), authored the Gyehae Jocheollok (癸亥朝天錄, Record of a Journey to the Imperial Court in the Gyehae Year). This work presents an intriguing phenomenon: the first three volumes, along with his earlier Imin Jocheollok (壬寅朝天錄), are written entirely in orthodox Literary Chinese, whereas Volume 4, which contains confidential reports to the Joseon court, is densely interspersed with Idu writing (吏讀). Why does the same author employ two radically different modes of writing within a single work? Adopting the perspective of register stratification, this article examines Yi Min-seong’s language choice strategies when addressing different audiences. The study finds that in the open register intended for Ming readers, he achieves procedural compliance and emotional communication through the strategic adaptation of Sinitic words; in the confidential register directed at the Joseon court, he relies on the grammatical marking system of Idu to realize the precise transmission of intelligence and secure communication. These two strategies together constitute Yi’s “dual writing,” which reflects the envoy’s identity adjustment under the dual missions of “serving the great” (sadae, 事大) and “loyalty to the monarch” (忠君). This case study offers a new entry point for understanding the writing mechanisms of Yeonhaengnok (燕行錄) literature.
