动感超人buibu
[dòng găn chāo rén buibu]
The username references an energetic superhero (Donggan Chao Ren is likely a made-up character combining Chinese 'donggan' meaning energetic/vibrant and 'superhero'). 'Buibu' is onomatopoeic sound like steps. So it can be seen as an lively superhero moving briskly.
