醉生梦死何乐而不为
[zuì shēng mèng sĭ hé lè ér bù wéi]
This phrase roughly means 'Why not live and forget your worries?' or 'What joy is there not to drown sorrows in revelry?' The username evokes themes of escaping life’s troubles through alcohol and revelry, a sort of 'living like there's no tomorrow' philosophy.
