Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
irene yan » irene a, ren yan
yang hua » wang hua, yang hui, ying hua
wang wei » zhang wei
thi hong » tan hong
yang xi » yang di, yang yi, 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((((yang hua) OR (yang xi))) OR (((wang wei) OR (wang zhi)))) irene yan thi hong yu ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ((((yang hua) or (yang xi))) or (((wang wei) or (wang zhi)))) irene yan thi hong yu ;*.
