等线 Bold

DengXian Bold (等线) is a modern sans-serif typeface developed by Microsoft to serve as a default font for Windows 10 and Microsoft Office 2016. It represents a significant shift in Chinese digital typography, designed specifically to replace older system fonts with a more contemporary 'Heiti' style. The font is characterized by its uniform stroke thickness and geometric structure, which provides exceptional clarity and legibility on high-resolution screens and mobile devices.

As the Bold weight of the family, this typeface is engineered to provide strong visual impact while maintaining the clean aesthetics of its regular counterpart. It removes the traditional flares and decorative elements found in older Mingti styles, resulting in a minimalist appearance that is highly favored in modern UI/UX design. Its development has made it one of the most recognizable and widely used fonts for Chinese-language digital interfaces, branding, and professional documentation.
