无路可走只能口是心非无路可退只能无言以对
[wú lù kĕ zŏu zhĭ néng kŏu shì xīn fēi wú lù kĕ tuì zhĭ néng wú yán yĭ duì]
'Having nowhere to go except lying; having nowhere to retreat only staying silent', conveying a state where truth is hidden because of the dilemma and retreating leads to silence since arguments are pointless. Describes a complicated situation where honesty feels impossible and defense seems futile.
