黎（li）
Name meaning
黎 (li) can mean numerous or the common people, and it also appears in 黎明 (liming), the approach of dawn. As a personal-name character it feels historical and literary, but many readers will recognize it first as a Chinese surname.
Practical naming use
黎 (li) carries a broad civic field through the people and a poetic transition toward dawn through the compound 黎明 (liming). It is culturally substantial but surname-like and uncommon as a standalone modern given-name character.
Use 黎 (li) only in a compound that makes the intended reading and image clear. A second character should supply the personal quality, because 黎 (Li) alone often looks like a surname.
Reference
Dictionary meaning
The Taiwan Ministry of Education dictionary records 黎 (li) as numerous, black or dark, approaching in the compound for dawn, and as a long-established Chinese surname.
For naming, the defensible positive fields are the people, multitude and the transition toward dawn; the character does not simply mean bright morning by itself.
Historical / name-use references
黎景熙 (Li Jingxi)
The Taiwan Ministry of Education dictionary cites the Northern Zhou figure 黎景熙 (Li Jingxi) as an old bearer of the surname 黎 (Li). Here 黎 (Li) is a surname, so this is historical identity evidence rather than proof of common given-name use.
