Standard transliteration of 'Surrey' (and homophone-spelled foreign names like Sarri):
萨 (sà, 'Su-/Sa-') +
里 (lǐ, '-rrey/-rri').
萨 is the default opener for English 'Sa/Su' starts (compare
萨克斯 Sax,
萨德 THAAD). Surrey is best known as commuter-belt for London; the University of Surrey is the major academic anchor.
