The followings are the characteristics of Kyunghakkwan of Youngjae Oh Yunsang. First, he delves into Soju (小注: Small notes or commentaries) of Saseo-Jibju-Daejeon (四書集註大全: Compendium of the Commentaries of Four Confucius Canons). Frequently adding, "thinking," "thinking again," he enumerates his own theories critical of various scholars who left commentaries in Daehak-Janggu-Daejeon (大學章句大全: Compendium of the sentences and phrases in Daehak, one of the canon) and Jungyong-Janggu-Daejeon (中庸章句大全: Compendium of the sentences and phrases in Jungyong, another canon). Secondly, he quotes theories of Korean confucius scholars. Besides Lee Yulgok, he introduces mainly theories of Nongam Kim Changhyub and Namdang Han Wonjin. Thirdly, he researches into various canons. He diverts from the general trend of Chosun confucius studies which focuses on Saseo and explores Seokyung (書經: One of Five canons of Chinese Confucius Studies and the oldest history book). Fourthly, his Kyungseol, especially that of Jungyong, was recognized and accepted by his contemporary Giho School scholars. Finally, he shows skepticism even on Confucius's own ideas and begs to differ.

Jeong Yak-yong attempted to establish a new philosophical system through the criticism on Neo-Confucianism. The most important area among the ideas of Dasan is on the ethical thoughts. He has a tremendous interest in the ethical education as well as ethical thought. During his exile, he gathered children around and educated them by editing "Jegyeong(弟經)". Dasan regarded "Sohak(小學)" to have some problems in educating children. Thus, he reconstructed the contents of "Sohak" and edited "Jegyeong". "Jegyeong" is more concise than Sohak and is a textbook focusing on children which is mainly composed of practical etiquette in the everyday life. It contains etiquettes to parents, teachers and adults, etiquettes on food in the everyday life and etiquettes between men and women. Although the contents does not exceed the scope of Sohak, he selected reasonable contents and composed with practical contents. Thus, it is practical. Dasan also attempted to make a novel interpretation on Saseo (四書), i.e., Noneo, Maengja, Daehak and Jungyong. His new interpretation on Saseo can be considered as ethical textbooks in a broad sense. Dasan considered the key ethical principle of Saseo (四書) to be Seo (恕). Accordingly, he thought it is very important to understand and practice ethical principle of Seo (恕). Dasan studied and annotated "Simgyeong(心經)" and "Sohak(小學)" for self moral discipline. And, he thought it is utmost important to understand and accept the existence of Sangje (上帝) in order to keep moral mind. He believed it to be important to have Gyesingonggu (戒愼恐懼), which is to aware and respect the existence of Sangje (god) for self discipline and Sindok (愼獨) to be cautious about things that only he was aware of. He thought that if people are aware of Sangje (上帝) and make dialog with Sangje, the will of Sangje could be expressed into Dosim (道心). In the ethical education, it can be said that, ultimately, the awareness on the absolute being is the most important point to Dasan.
