卷乌纱
[juăn wū shā]
The character “乌纱” (Wū shā) historically refers to a black gauze hat which was part of officials’ dress during certain periods in Chinese feudal society. ‘卷乌纱’ (juǎn wū shā) could imply losing one's official rank or experiencing setbacks in an official career. It carries some sense of satire or self-mockery now and is often used by those implying they’ve encountered trouble in their professional or life journey.
