英文释义

谚语
  1. A condemnation of anyone who damages their own group, reputation or interests.
    — They say it's an ill bird that fouls its own nest. My own feeling is that a well-behaved bird will neither foul its own nest nor another's, but that, finding it in any wise foul, it will openly say so, and clean it.
