黎许
[lí xŭ]
'黎许' is composed of two characters, '黎' (Li) and '许' (Xu), both can be surnames, thus, one's online ID could just simply combine two surnames to form its unique style; alternatively, the character '黎' refers to dawn as well and '许' could express multitude in classical Chinese. So '黎许' may symbolize many dawns, metaphorically describing hopes coming again and again, never ending.
