The creative source of the campus youth comedy "Basketball Girl" is taken from the ancient Chinese "Mulan Joins the Army". The same scenario of a girl dressed as a man is assumed in the modern civilized and advanced world. The girl is dressed like a man, imitates the man's speech and behavior, lowers her voice and makes it thicker. The necessary chest binding, going to the toilet, taking a bath, and other ridiculous props make people very interested. The emotional puzzle of the love triangle in the film, plus the identity farce of a girl dressed as a man, makes the impossible task of a girl dressed as a man possible. It is said that martial arts films are adult fairy tales for men, so this film can also be regarded as a beautiful fairy tale for teenagers.
