The 80,000 blocks, made in the period of Koryo, a feudal state of Korea (early 10th century-late 14th century", in 16 years from 1236, provides a glimpse of the nation's advanced printing technique.

The completion, printed on both sides, is made up of 1,539 parts and 6,793 volumes.

The blocks are still kept in their origin.

The completion is considered a world-standard one in the correctness of content.

When visiting the Myohyangsan History Museum in June Juche 78 (1989), President Kim Il Sung learnt that only some of the blocks were on display and suggested that all of them be exhibited for visitors.
