The exact number of books of the "Chosun Dynasty Annals," a UNESCO world heritage of history, which is a valuable document detailing what happened in the Joseon Dynasty, was revealed only for 46 years after the National Treasure.

The Cultural Heritage Administration announced that it would identify the existence of 96 books including the Choson dynasty records,

The annals of the Joseon Dynasty were designated as National Treasures No. 151 in December 1973, and the accident that kept the Chosun Dynasty annals was originally built in Hanyang, Jeonju, Chungju, and Sungju.

Some of the books that were announced to be added to this year were at the Institute of Korean Studies at Seoul National University Kyujanggak, but they were omitted from the 1970s designation survey and the book of Ota Daisan was the "Hyojong Annals" purchased by the Cultural Properties Agency last March from a cultural property trader.

In particular, it was revealed that the four books of the Mt. Sangsan Mountain accident, which was reported to have been carried out by the North Korean forces during the Korean War, were kept in the National Museum and the Korea Research Institute.

Hwang Jung-yeon, a professor at the Cultural Heritage Administration of Korea, said, "It was discovered that the first four episodes of the accident in the late Joseon Dynasty were reported to the Korean people, I look forward to helping you. "
