Self-sufficiency
（重定向自Selfsufficient）
Self-sufficiency (also called self-containment) is the state of not requiring any aid, support, or interaction, for survival; it is therefore a type of personal or collective autonomy. On a national scale, a totally self-sufficient economy that does not trade with the outside world is called an autarky.
