富足 (fù zú) is an adjective meaning 'well-provided' or 'self-sufficient', describing a state of having enough—especially in material resources, food, or basic needs—to live comfortably and without lack. The character 富 (fù) means 'wealthy' or 'abundant', while 足 (zú) literally means 'enough' or 'sufficient'; together, they emphasize adequacy and security rather than excess or luxury. It often conveys a sense of quiet contentment and stability.

This word is commonly used to describe households, communities, or lifestyles where essential needs are reliably met—such as in rural villages with ample harvests, or families with steady income and strong social support. It appears frequently in formal writing, news reports on livelihoods, and discussions about quality of life, but is less common in casual speech than simpler terms like 有钱 (yǒu qián, 'to have money') or 够用 (gòu yòng, 'enough for use').
