Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang muxi » yang jui, yang xi, yang mu
irene tan » irene a, rene ten
yang hui » yang jui, wang hui, zhang hui
hoang yu » hoang vu, hong yu, hoang _
hoang sy » hoang vu
tan li » tang li, tian li, gan li

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((yang hui) OR (yang muxi)) irene tan li ((hoang yu) OR (hoang sy)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang hui) or (yang muxi)) irene tan li ((hoang yu) OR (hoang sy)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang hui) or (yang muxi)) irene tan li ((hoang yu) OR (hoang sy)) ;*.
