朱古力 is the Cantonese-origin transliteration of 'chocolate' (jyu1 gu2 lik6) and is the standard word in Hong Kong, Macau, and overseas Cantonese communities. Mainland Mandarin uses
巧克力 (qiǎokèlì) instead — both refer to the same thing, but using
朱古力 in mainland writing instantly signals a Hong Kong or Cantonese context.
