Three-syllable phonetic transliteration.
马 (mǎ, 'horse') is the standard Mandarin character for the 'Ma-' sound in foreign names (
马克 Mark,
马丁 Martin);
舒依 (shūyī) renders 'shu-i' / 'sui'. The combined sound suggests names like 'Mashui' or 'Massui' — most likely from a translated novel rather than a famous public figure.
