清了梦浊了酒
[qīng le mèng zhuó le jiŭ]
Translated loosely as 'clears dreams but sours drinks'. 'Dreams become crystal clear' signifies gaining awakening and comprehension. However, at the same time, 'wine becomes turbid,' implying the joy of life may get disturbed by confusion, uncertainty, troubles or sorrows after enlightenment. It describes a somewhat pessimistic outlook on life and wisdom
