健（jian）
Name meaning
健 (jian) means strong, healthy and vigorous. In names it suggests disciplined strength and steady self-improvement.
Practical naming use
健 (jian) is a sturdy character for names that should feel healthy, active and disciplined. It should not be reduced to physical fitness; the strongest cultural reading is self-strengthening, resilience and the ability to keep moving with purpose. It works especially well for grounded masculine-neutral names.
Pair 健 (jian) with culture, brightness or sincerity: 健文 (Jianwen), 健明 (Jianming), 健诚 (Jiancheng) or 健安 (Jianan). Avoid another forceful character if the name becomes hard or athletic only.
健文 (Jianwen): Jian contributes healthy, strong; Wen adds culture, writing.
