无所谓好坏
[wú suŏ wèi hăo huài]
It translates directly as 'There is no right or wrong', which conveys an indifferent attitude towards outcomes or situations. In Western contexts this can be understood as adopting an easy-going or philosophical outlook on life's choices and judgments, refusing to overly concern oneself with conventions and standards, seeking personal peace within oneself despite surrounding circumstances.
