Our paper Hanji was passed down through the generation from China since the 2nd century to the 7th century. The world's oldest "Great Dharani Sutra of Immaculate and Pure Light (Mugu jeonggwang dae daranigyeong) "was excavated in 1966 from Seokgatap at Bulguksa Temple in Gyeongju.
From this, it is evident that Hanji can be sustained for thousands of years. Hanji culture most thrived during the Joseon Dynasty and the Koryo Dynasty era. During the Koryo Dynasty, our paper, which was called the "Koryo-Ji (Koryo paper)," was exported to China's Song Dynasty and has been historically recorded as high-quality paper. From the year 1145 (Injong 23) to 1188 (Myeongjong 18) during the Koryo Dynasty paper, manufacturing factories were established, indicating that handmade papers were actively being produced. From Joseon Dynasty, Joji-so (government office for paper production) was each installed in 1415 (Taejong 15) and 1466 (Sejong 12), resulting in developing hanji by managing the quality and quantity of paper within the country.
According to currently remaining sources, mostly Buddhist scriptures and Confucian scriptures could be examined. After all, it reveals the nation's ideology of Buddism during the Koryo Dynasty and policies were included to strengthen the country by spreading the Confucian ruling ideas during the Joseon Dynasty. Just like the nation's ideology, these historical records have been maintained with its ever-lasting lives for a thousand years.
