'Page eyebrow' is a vivid, literal translation of 页眉 (yè méi), the standard Chinese term for 'header'—the section at the top of a printed or digital page that often contains titles, page numbers, dates, or document identifiers. The character 页 (yè) means 'page', while 眉 (méi) means 'eyebrow', evoking the idea of something positioned above and framing the main content like eyebrows frame the eyes.

This term is used almost exclusively in document formatting contexts: word processors (e.g., Microsoft Word), PDFs, academic papers, official reports, and web page layouts. It contrasts with 页脚 (yè jiǎo, 'footer'), which appears at the bottom of the page. While the metaphor may seem unusual to English speakers, it's universally understood in Chinese technical and office environments—and never used for actual body parts or biological features.
