Phonetic transliteration of Gucci. The brand's official Chinese name is now
古驰 (Gǔchí), but
古琦 was a common earlier rendering and still appears in subtitles and older media.
古 (gǔ-) approximates 'gu-' and
琦 (qí) approximates the '-ci' coda, with
琦 carrying a flattering 'fine jade' meaning typical of brand transliterations.
