Samiheon Jang Bok Chu was a 8th-generation-passed successor of Yeoheon Jang Hyeon Gwang. He succeeded the learning tradition of Hangang·Yeoheon scholars` sector, non-mainstream group of Yeongnam scholars` sector and connected it to the learning tradition of Toigye scholars` sector. He devoted all his effort in re-configuring the idea of Yeoheon ``to restore his isolated ancestors` learning and idea``. In addition, he accepted Daesan Lee Sang Jeong style Toigye`s learning and upgraded it in order to restore Jang Hyeon Gwang`s learning in the tradition of Toigye`s learning. Furthermore, he showed favor to Nammyeong scholars` sector and Nammyeong learning itself supporting Yeongnam scholars` sector at both sides together with Toigye scholars` sector, and made efforts to integrate Toigye learning and Nammyeong learning. Succeeding his ancestor Jang Hyeon Gwang and Hangang Jeong Gu`s academic features, he tried to combine such features to genuine Yeongnam scholars` sector for complete integration in terms of both idea and spirit with his life-long efforts. The word ``integration`` is the feature of Samiheon`s academic spirit. Jang Bok Chu`s academic tendency aiming at ``integration`` at the most is thought to be an example rarely seen in Korean modern history of Confucianism. Jang Bok Chu`s position in the history of Joseon Confucianism is thought to be findable by being related with such features set forth above.
