笑（xiao）
Name meaning
笑 (xiao) means smile, ease and bright human warmth.
Practical naming use
笑 (xiao) should not be reduced to childish cheer. In classical writing it can mean ease, confidence and emotional brightness, and the Water Margin nickname Smiling Tiger gives it a memorable name-use anchor. Used well, it feels warm and lively rather than cute for its own sake.
Pairing guide
Pair 笑 (xiao) with characters such as 宁 (Ning) for softer ease, 文 (Wen) for cultivated warmth, 安 (An) for calm brightness or 怡 (Yi) for pleasant feeling. The second character should keep the name human and composed.
笑安 (Xiaoan): Xiao contributes smile, joy; An adds peace, safety.
