In Fire Military Academy, Gu is a rich man who looks cynical on the surface, but in fact, he is also a smart and witty young man. Just the title introduced to him in the first episode is enough to let people know that his family background is very large: the son of Gu, executive vice minister of the Ministry of the Interior, the grandson of Hu Liuweng, director of education, and the nephew of Commander Hu and Xu's brother-in-law. Of course, after ten episodes, we found that Gu was not superficial. He is witty and humorous, and his judgment of the situation is clear. Perhaps the apparent absurdity and rebellion are just the appearance of his confusing others.
