醉者不懂
[zuì zhĕ bù dŏng]
It translates into the intoxicated ones do not understand. This can imply two meanings - firstly people might choose to act foolish under intoxication to mask real feelings; and alternatively, that sometimes those immersed in certain emotions (e.g., sadness or love) are unaware or unable to control themselves, just as an drunken person may not fully understand their actions.
