Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
wang yang » wang yan, wang liang, wang yanling
shang hai » shang kai, dang hai, chang ha
zhuo lee » choo lee
yang li » yang lin, yang di, yang xi
hua lee » hwan lee, phua lye
hong yu » wong yue

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yang li ((hua lee) OR (zhuo lee)) sang minh ((shang hai) or (hong yu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang li ((hua lee) OR (zhuo lee)) sang minh ((shang hai) OR (hong yu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang li ((hua lee) OR (zhuo lee)) sang minh ((shang hai) or (hong yu)) ;*".
