Chen Xia is a character in the movie Big Brother, played by Donnie Yen. Chen Xia's mother died when he was very young. His father ran away from home and his aunt took care of him. When I was a teenager, I studied in Dezhi Middle School and was later expelled from school. My aunt and my family immigrated to America.

Later, Chen Xia became a member of the US Marine Corps, because the war experienced psychological pain. Being a teacher at my alma mater, I want to find myself. I not only accept the teaching conditions of no teacher allowance, no off-duty time and no lateness for work, but also cultivate a group of delinquent teenagers who are about to be expelled.

Big Brother is an action comedy film directed by Kan Jiawei and starring Donnie Yen, Chen Qiaoen, Luo Mingxi, Jingyun Li and Yu Kang. The film was released in China on August 24, 20 18. The film tells the story of a retired special soldier who returned to his alma mater to teach and fought side by side with the problem students in the teaching process to help them correct their mistakes.

As an audience of action movies, the most feared plot is that the hero will grow old and become a sanctimonious old-school appearance. I like Master Brother better, that is, the transformation of Donnie Yen. Educational criticism is not cynical, but it is still a gentle comedy, interspersed with A-level action scenes.
