不乏 is an adverbial phrase meaning 'not lacking' or 'no shortage of.' It combines 不 (bù, 'not') and 乏 (fá, 'to lack' or 'to be short of'), forming a concise, formal expression used to emphasize abundance or sufficiency of something—often qualities, examples, or resources. Unlike colloquial alternatives like 很多 or 大量, 不乏 carries a slightly literary or journalistic tone and frequently appears in written Chinese, news reports, academic writing, and formal speeches.

The phrase typically modifies nouns or noun phrases and often introduces evidence, examples, or notable cases: e.g., 不乏成功案例 (no shortage of success stories) or 不乏优秀人才 (no shortage of outstanding talent). It usually occurs after the subject and before the verb or predicate, and it’s rarely used in casual spoken conversation. Its formality makes it especially common when highlighting positive attributes without overstating them.
