无需闭月羞花倾国倾城

This username 'No Need to Make the Moon Hide Its Light or Shame the Blooming Flowers; World-stunning Beauty' originates from classical Chinese literature used to praise women of unparalleled beauty who can overshadow the moon and flowers and even bewitch nations with their loveliness. However, by using the negative form here, it implies that physical attractiveness isn't everything and that the owner is someone with self-appreciation beyond mere appearances, emphasizing personality and inner beauty instead of vanity or material pursuits.
