行（xing）
Name meaning
行 (xing) means conduct, action, the road one walks and learning through movement.
Practical naming use
行 (xing) is a strong action character because it joins conduct with movement. In classical Chinese it can mean to act, to travel and to carry oneself, so the name feels practical, purposeful and morally active rather than restless. With Wu Song's nickname Xingzhe, it also gains a memorable fiction anchor.
Pair 行 (xing) with characters such as 文 (Wen) for cultivated conduct, 宁 (Ning) for steadier movement, 远 (Yuan) for longer vision or 安 (An) for grounded action. The second character should humanize the motion.
行安 (Xingan): Xing contributes conduct, journey; An adds peace, safety.
