In Korea, the function of Jeong(亭), Jeongja(亭子), and Nujeong(樓亭) architecture is essentially rest. However, in China, where the name Jeong was first coined and used, Jeong was not only used as a place of rest, but also for a variety of functions depending on the time and region, such as building units for guard posts, policing, and mail delivery. But why is it that in Korea, Jeong is primarily perceived and used as place of rest? Starting from this question, this article examines the historical process of the emergence of Jeong and its changing functions, focusing on the official history of China, and then examines the perception of Jeong in Korea through its connection to the dominant function of Jeong in China during the period of Jeong's emergence in Korean literature. This will help us to fundamentally understand the differences between Jeong architecture in Korea and Jeong architecture in China, and to further clarify the historical significance of the types of Jeongja and Nujeong architecture in Korea.
