Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
irene yan » irene a, ren yan
yang hua » yang hui, ying hua, yang jui
wang hui » wang zhi, wang wei, wang he
thi hong » tan hong
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.

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