According to the answer obtained from a name pinyin query website in Hong Kong: Du Wei Tao Wai or To Wai, but in fact this is Hong Kong pinyin, if it is the Cantonese pinyin from Guangdong (it is also written on that website) Wei It’s the same, but Du should be dou6 (dou6 represents the sixth tone. If there is no you in Mandarin, just pronounce it dou...) And when I usually say Du, I always pronounce the sound dou.
