Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang yong » wang yang, wang hyoung, wang yan
irene yan » irene a, ren yan
thi hong » tan hong
yang xi » yang di, yang jui
yang yi » yang di, yang jui
yan thi » yan zhi, tran thi, dang thi
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: ((yang yang) or (wang yong)) ((yang xi) OR (yang yi)) irene yan thi hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang yong)) ((yang xi) OR (yang yi)) irene yan thi hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang yong)) ((yang xi) OR (yang yi)) irene yan thi hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang yong)) ((yang xi) OR (yang yi)) irene yan thi hong yu ;*.
