1917년 훈춘 대황구에서 건립한 북일학교는 독립군양성을 위해 나자구 동림무관학교의 전통과 대황구 동창학교의 기반을 통합적으로 발전시킨 민족교육기관이자 독립군양성기관으로, 독립군양성, 민족주의 함양, 기독교주의 등을 교육 이념으로 내세웠다.
대황구는 교통이 불편하여 중국 지방 당국의 영향력도 상대적으로 덜 미치는 곳이었으나, 러시아의 연해주와 인접한 지리적 조건 때문에 북간도와 연해주를 잇는 독립운동의 통로로 적당한 곳이었으며, 일찍부터 한인들이 이주하면서 한인사회를 형성하고 있었다. 그리고 일찍부터 이동휘와 동지적 관계를 맺고 있던 대황구 社長 양하구 등이 적극적으로 이동휘의 제안을 받아들이면서, 나자구 동림무관학교와 대황구 동창학교를 통합한 북일학교가 새롭게 탄생하였다.
건학 초기에는 이동휘를 따르며 간민회, 동제회, 결사대, 동림무관학교 등에서 다년간 독립운동을 펼친 30대 인사들이 주로 교원을 맡았으나, 이들이 이동휘를 따라 연해주로 떠난 뒤에는 훈춘 또는 대황구 출신들이 교원으로 충원되면서 훈춘지역 독립운동을 주도해 나갔다.
북일학교 구성원들은 3ㆍ13운동을 추진하는 한편 훈춘 영사분관을 무력으로 공격할 계획을 세우면서 독립군적 투쟁으로 전환해 갔다. 교원과 학생들이 훈춘 군무부, 철혈광복단, 한민회, 최진동의 대한독군부, 홍범도의 대한독립군 등 북간도 독립군단체에서 중추적 역할을 담당하면서 북일학교는 명실공히 독립군 산실로 역할하였다. 특히 훈춘국민의회의 결사대 및 홍범도의 대한독립군 성립에 이들 북일학교 구성원은 굳건한 버팀목으로 자리하고 있었다. 북일학교 구성원들이 무장투쟁의 전면에 나서기까지는 1914년 동림무관학교 이래 오랫동안 축적한 역량에서 가능한 것이었다.
Bookil School which was established in Daewhanggu, Hunchun in 1917 and unified and developed the tradition of Najagu Donglim School to train military officers and the basis of Dongchang School in Daehwanggu (大荒溝) was a national educational institution as an institution to train an army for national independence, and its principle of education was training an army for national independence, cultivating nationalism, and Christianism.
As Daehwanggu was located in the place where lacked traffic facilities, local authorities of China do not have great influence on this place relatively, however, as geographically it was located near Primorie, Russia, it was suitable to connect North Gando (North Jiandao) with Primorie as a passage for an independence movement. And formerly Koreans emigrated to this area from Korea and Korean society was formed. As Ha-Gu Yang who was a president of a company in Daehwanggu and maintained friendly relations with Dong-Hui Lee positively accepted Dong-Hui Lee's proposal to establish a school, Bookil School which unified Najagu Donglim School to train military officers and Dongchang School in Daehwanggu was newly established.
In its early stage, the figures in thirties who followed Dong-Hui Lee and took part in the independence movement in the societies like Ganminhoi, Dongjehoi, Do-or-die corps (Gyeolsadae), Donglim School to train military officers and others were in charge of school affairs, however, the people from Hunchun or Daehwanggu were filled in for empty seats after their leaving for Primorie following Dong-Hui Lee and they led the independence movement.
As the members of Bookil School propelled 3.1 Independence Movement and made a plan to attack the Japanese consulate in Hunchun by force, their anti-Japanese struggle changed to armed one like an army for independence movement. As its teaching staffs and students played a pivotal role in the societies of the army for independence movement in North Gando like Army section in Hunchun, Cheolhyeol Kwangbokdan (Blood-and-Iron Society for Independence), Hanminhoi, Daehandokgunbu (Korea's Armed Forces for Independence) led by Jin-Dong Choi, Korea's Army for Independence Movement led by Beom-Do Hong, etc., it played the role of a delivery room for an army for independence movement. In particular, its members firmly took part in the establishment of the do-or-die corps of National Assembly in Hunchun and Korea's Army for Independence Movement led by Beom-Do Hong. Its ability accumulated for a long time since the establishment of Donglim School to train military officers in 1914 made it possible for its memebers to be in the forefront
