愚梦不醒
[yú mèng bù xĭng]
This username 'Yu Meng Bu Xing' means 'A Foolish Dream That Never Wakes'. Here, the creator of this name expresses that one is deeply immersed in a fantasy or an impractical dream like it were reality and does not wish or dare to leave. In Chinese culture, a dream could be regarded as hope or something people are eager for deep down. A fool usually refers to someone who is simple and innocent, which can also be interpreted as purity here.
