"Marco Education" was formally established. Over 170 Linux System engineers have been trained for two years of teaching!

Mago education has been in operation for two years and has trained more than 170 Linux System Engineers. Most of the students who are still in school are employed in Shanghai and Beijing. After time verification, our courses and teaching can closely follow the requirements of Linux O & M and system-related positions, and bring practical job skills to the students, which are also well received by them!

Our idea of running a school is to run a responsible training school in a non-commercial mode to help more friends fulfill their personal dreams!
