一挽苏夏

One way of translating could be 'A Stroke to Awaken Xia (or Suzha).' It appears rather enigmatic. It might be related to certain stories in literature where someone named Xia has been awakened by some act symbolized as a 'stroke', or just purely used because these characters form a beautiful combination of strokes aesthetically pleasing visually, phonetically and meaningfully. This kind of online moniker carries literary value and aesthetic appreciation.
