戴沃 is a phonetic transliteration. The standard Mandarin name for the Swiss town of Davos is usually
达沃斯 (Dáwòsī), so
戴沃 most often functions as a personal-name rendering ('Devo', 'Davo', or a similar foreign nickname).
戴 (dài, to wear) and
沃 (wò, fertile) are picked for their sound, not their meaning.
