端（duan）
Name meaning
端 (duan) means uprightness, proper form and well-begun order. In naming it reads as principled bearing and correctness, not stiffness.
Practical naming use
端 (duan) is an uprightness-and-form character. It gives a name dignity, rectitude and orderly presence, so the result feels proper rather than severe. 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 端 (duan) with characters such as 安 (an) for settled uprightness, 文 (wen) for cultivated form, 明 (ming) for clear rectitude or 宁 (ning) for composed dignity. The second character should keep the name proper without making it stiff.
端正 (Duanzheng): Duan contributes upright, proper; Zheng adds upright, correct.
