The term "zhao lusi" functions as a proper noun. A proper noun is a specific name used for an individual person, place, or organization, and it is always capitalized in English writing. As a proper noun, it identifies a unique entity, distinguishing it from all others of the same class.
In grammatical analysis, a proper noun serves as the subject, object, or complement in a sentence, just like a common noun (e.g., "actress," "woman"). The key distinction is its specificity. While "actress" is a common noun referring to a general category, "zhao lusi" refers to a singular, specific individual. This classification is crucial because it dictates that the subject of the article is not an abstract concept or a general category but a particular person, framing the entire discourse around her identity, career, and associated events.
Therefore, recognizing "zhao lusi" as a proper noun is the foundational step in content strategy. It establishes that the article's main point will be descriptive or analytical information about a specific person. All content, whether biographical details, filmography analysis, or discussions of her public image, will directly relate to this central, named subject.
