真（zhen）
Name meaning
真 (zhen) means real, genuine, true and not false. In a given name it should suggest sincerity, integrity and a person whose character does not depend on display.
Practical naming use
Use 真 (zhen) when the name should feel honest, direct and morally grounded. It suits scholarship, law, teaching, public service, counselling or any identity where trust matters. Pair it with a character that adds warmth or refinement so the name does not become blunt.
Pair 真 (zhen) with a character that gives the truth a humane direction: 真安 (Zhenan) Zhen'an for settled honesty, 真文 (Zhenwen) for cultured sincerity, 真明 (Zhenming) for clear judgment or 真德 (Zhende) for moral weight. Avoid a second severe virtue word if the name starts to sound admonishing.
真安 (Zhenan): Zhen contributes true, genuine; An adds peace, safety.
