Twenty-seven years ago, Zhang Juncheng, a security guard at Peking University, passed his self-study and was admitted to Peking University's law major. He is also known as "the first security guard at Peking University".

In 1999, Zhang Juncheng returned to his hometown, Changzhi City, and went to teach in many vocational schools, always sticking to the front line of the education industry.

  Now, Zhang Juncheng has become the principal of a private secondary vocational school, and he is full of peach and plum.

Since 2002, Zhang Juncheng will personally send candidates to the college entrance examination room every year during the college entrance examination.

  From the security guard of Peking University to the principal of vocational high school, Zhang Juncheng regards the school as a place to prove himself, and at the same time as a battlefield to lead his students to achieve a counterattack in life.
