A more thorough explanation:

Definition: Polyandry is the practice of having more than one husband at the same time. It is the opposite of polygyny, which is the practice of having more than one wife at the same time.

Example: In some cultures, such as the Mosuo people in China, polyandry is a traditional practice. In this society, a woman may have multiple husbands who all share in the responsibility of raising any children that she has.

Explanation: The example of the Mosuo people illustrates the definition of polyandry because it shows a culture where it is accepted and even expected for a woman to have multiple husbands. This is different from the more common practice of monogamy, where a person has only one spouse at a time.
