obligation

In Chinese, '义务' refers to an action or a state that one is bound to by duty, legality or morality. It is usually used to express obligations in social, moral, and legal contexts. For example, paying taxes is a '义务' that you must fulfill as a citizen. It can also refer to a service or a favor you are expected to do without pay because it is morally right or legally required.
