Firstly, since Jaryujuseok was exposed to the world, the Myeoknam edition has been known widely as the original edition. However, the details show that the Myeoknam edition is not the original edition. The most important evidence is that there are remarks from other one and the handwriting is the same. Seconedly, the texts are highly focused while the preface and appendix are ignored. We should pay more attention to them. For example, the auther cited Gaiyucongkao in a wrong way. Lastly, Jeongjo’s name, Seong, is recorded by Jaryujuseok. Jaryujuseok explained Seong in Korean for the first time. According to the explanation, we can make a conclusion that Seong means Review.
