The Chinese word "那不勒斯" is formed through phonetic transliteration, where each character is chosen solely for its sound to approximate the foreign name "Naples". The character "那" (nà) corresponds to "Na", "不" (bù) to "po", "勒" (lè) to "le", and "斯" (sī) to the "s" sound, combining to replicate the pronunciation without regard to the individual meanings of the characters.
