Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
ying minh » ying jin, sang minh, yang mind
wan yang » wang yang, dan yang, tan yang
xi irene » _ irene, i rene
cong hai » hong hai, dang hai, long han
cong van » congo can, duong van, cong sun
ii rene » iii rene, i rene, wie rene

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yang yang ((xi irene) OR (ii rene)) ying minh ((cong hai) or (cong van)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yang yang ((xi irene) OR (ii rene)) ying minh ((cong hai) OR (cong van)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yang yang ((xi irene) OR (ii rene)) ying minh ((cong hai) or (cong van)) ;".
• Adding a wildcard symbol may retrieve word variants: wan yang yang ((xi irene) OR (ii rene)) ying minh ((cong hai) or (cong van)) ;*.
