"Shantou film" is a kind of oral expression with certain regional color, which is mainly popular in northern China, especially in Beijing. This phrase is used to address young women, especially those who are young and inexperienced. In ancient times, the word "girl" was a general term for young women, but "movie" had no practical significance here. It is similar to a phonetic expression to emphasize the youth and innocence of "girls". This usage is very common in spoken English and plays a role in strengthening mood. Generally speaking, "girl film" is a vocabulary full of life breath, which embodies the vivid humor of the northern dialect.
