Perhaps you should try some spelling variations:
yang xiang » yang liang, wang liang, yang yang
lang ying » liang ying, huang ying, zhang ying
rong john » wrong john, kong john, wong john
tonga eiu » kong eiu
dong sign » dong sin, among sign, dong bin
yang xi » yang di, yang yi, yang jui
li rong » yi rong, li cong, 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 rong john ((tonga eiu) OR (dong sign)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ying ((yang xi) or (yang xiang)) li rong john ((tonga eiu) or (dong sign)) ;*.
