丽莉 is one of several common Chinese transliterations of Lily / Lili (others:
莉莉,
丽丽,
莉莉安 for Lillian). Both characters here are female-name workhorses —
丽 (beautiful) and
莉 (jasmine, from
茉莉 mòlì). Often used by Chinese parents who want a name that sounds Western but reads as elegantly feminine in Chinese.
