Chinese Typography Sans-Serif Design

This is a sans-serif font with a wider face, slightly lower center of gravity, and open counters, based on a humanist structure. The overall layout is compact but not crowded. Strokes have low contrast, with horizontals slightly thinner than verticals. Curves are full on the outside and tight on the inside, using small-radius rounded corners and slight diagonal cuts at the ends. Character spacing is tight but internal whitespace is sufficient. Repeating components maintain identical curvature. Core identifying characters include lowercase a, e, the number 2, and uppercase R. Bold versions increase weight by expanding the inner stroke rather than compressing counters.

Aspect Ratio: {argument name="aspect ratio" default="16:9"}

这是一款字面偏宽、重心略低、字腔开放的无衬线体，骨架以人文主义结构为主，整体紧凑但不拥挤。笔画低对比，横画略细于竖画，曲线外侧饱满、内侧收紧，转角采用小半径圆角，末端多为轻微斜切。字距偏紧但内部留白充足，重复部件保持相同曲率，其中小写 a、e、数字 2 和大写 R 是核心辨识字符，粗体通过扩展笔画内侧而非压缩字腔来增加重量。
