Perhaps you should try some spelling variations:
liang yang » liang ying, wang yang, huang yang
yang yang » wang yang, wang yan
john wong » john song, john bonn
lin ying » li ying, lin ling, liang ying
jin ying » li ying
wong sam » wong sau, wong lai, kong sar
yang li » yang lin, yang di, yang xi

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: liang yang yang li ((lin ying) OR (jin ying)) john wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: liang yang yang li ((lin ying) or (jin ying)) john wong sam ;*.
