The Chinese word "杜嘉班纳" is formed through phonetic transliteration of the Italian brand name "Dolce & Gabbana", where each character is chosen to match the sounds of the original name: "杜" (dù) corresponds to "Do", "嘉" (jiā) to "ce", "班" (bān) to "ba", and "纳" (nà) to "na", resulting in a sequence that replicates the pronunciation without conveying meaning.
