Perhaps you should try some spelling variations:
yang xiang » yang liang, wang liang, yang yang
lang ying » liang ying, huang ying, zhang ying
wong john » wrong john, kong john, longo john
kong eiu » tonga eiu
dong bin » dong sin, dong di, dann bin
yang xi » yang di, yang yi, yang jui
li wong » li cong, li rong, li song

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: lang ying ((yang xi) OR (yang xiang)) li wong john ((kong eiu) OR (dong bin)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ying ((yang xi) or (yang xiang)) li wong john ((kong eiu) or (dong bin)) ;*.
