volunteer

Refers to people who voluntarily contribute their time and energy to improve social services and promote social progress without any material remuneration.

Voluntary work has four characteristics: voluntary, unpaid, public welfare and organizational. Taking part in voluntary work is both "helping others" and "self-help", as well as "enjoying others" and "enjoying oneself".

Participating in voluntary work is not only to help others and serve the society, but also to convey love and spread civilization.

Personalization and humanization of voluntary service can effectively narrow the spiritual distance between people, reduce alienation, and play a positive role in alleviating social contradictions and promoting social stability.
