雪（xue）
Name meaning
雪 (Xue) means snow, purity, cold brightness and cleansing clarity.
Practical naming use
雪 (xue) is one of the clearest purity-and-scene characters in Chinese naming. It brings snow, silence and cold brightness, so the name feels clean, distinct and emotionally composed rather than sugary. The Tang poem and Xuedou name together give it both poetic and spiritual depth.
Pair 雪 (xue) with characters such as 宁 (Ning) for calm purity, 文 (Wen) for literary clarity, 影 (Ying) for softer atmosphere or 晴 (Qing) for brightness after snow. The second character should keep the name lucid rather than icy.
雪宁 (Xuening): Xue contributes snow, purity; Ning adds peaceful, settled.
