常病酒
[cháng bìng jiŭ]
'Chang Bingjiu' refers to the habit of getting sick due to drinking. On one hand, it may directly refer to having poor tolerance for alcohol and easily falling ill after drinking; on the other hand, it might metaphorically imply the sadness or troubles caused by over-indulgence into something like romance or dreams which are just similar to excessive alcohol consumption in its consequences.
