飞（fei）
Name meaning
飞 (fei), traditional 飛 (Fei), means to fly, rise or move swiftly through the air. In a given name it should suggest upward motion, freedom and aspiration, not restlessness.
Practical naming use
Use 飞 (fei) when the name should feel energetic, open and upward-moving. It suits creative work, study, travel, public service, sports or any identity that needs lift and momentum. Pair it with a calmer character so the name feels purposeful.
Pair 飞 (fei) with grounding characters such as 飞安 (Feian) Fei'an, 飞文 (Feiwen), 飞远 (Feiyuan) or 飞扬 (Feiyang). Avoid another very fast or restless character if the whole name feels unstable.
