庚（geng）
Name meaning
庚 (geng) means the seventh heavenly stem, metal order and old calendrical firmness. In naming it reads as archaic structure and star-metal clarity, not daily warmth.
Practical naming use
庚 (geng) is a calendrical-and-metal-order character. It gives a name firmness, old-system rhythm and bright structural force, so the result feels antique rather than vague. It is especially useful for cultural depth, classical or literary reference, personality image, because the character can carry a recognizable Chinese image without becoming empty dictionary filler. The best results come when the second character adds human direction, warmth, restraint or breadth, so the full given name feels lived-in rather than generic.
Pair 庚 (geng) with characters such as 安 (an), 宁 (ning), 明 (ming) or 星 (xing) if an old-style, ordered tone is specifically wanted. The second character should humanize the calendrical feel.
庚辰 (Gengchen): Geng contributes seventh heavenly stem, firm metal image; Chen adds celestial time, stars.
Use notes
