‘仔肩’ is a literary, formal noun meaning 'one’s duty,' 'responsibility,' or 'burden'—often implying a weighty, morally significant obligation one must shoulder. The character 仔 (zǐ) here is an archaic variant meaning 'to attend to carefully' or 'to take seriously,' while 肩 (jiān) literally means 'shoulder,' evoking the physical act of bearing something heavy. Together, they form a vivid metaphor: duty as something carried on one’s shoulders, requiring diligence and resolve.

This term appears primarily in classical texts, formal speeches, essays, or solemn declarations—not in everyday conversation. It carries a tone of gravity, integrity, and self-sacrifice, often used when referring to national, familial, or ethical responsibilities. Modern speakers may encounter it in idioms like ‘共担仔肩’ (to share a solemn duty) or in political or educational rhetoric emphasizing moral accountability.
