There are many ways to pronounce the name, it should be Wei*Wei, it could be the one mentioned above it could be Bo Wei.

There is no fixed pinyin rule for Chinese names in Singapore and Malaysia, they are translated into English according to the dialectal pronunciation of their own ancestry, and one pronunciation can correspond to different Chinese pronunciations, and the same Chinese character can be translated into different spellings.
