한시, or "Han poetry," is a traditional form of Korean poetry that originated during the Goryeo Dynasty and flourished in the Joseon Dynasty. It is characterized by its use of classical Chinese characters and often follows specific structures, such as regulated verse. Han poetry typically explores themes of nature, love, and philosophical reflections. The language of 한시 is rich and expressive, allowing poets to convey deep emotions and thoughts in a concise manner. Many famous poets, such as Lee Hwang and Kim Si-seup, contributed to this literary form, leaving a lasting impact on Korean literature and culture.
