Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
fang yuan » wang yuhan, wang yan, meng yuan
sang minh » kang minah, anh minh, song min
minh kann » man kann, ich kann
wing ian » twinn ian, wing sun
wing tan » liang tan, hong tan, tin tan
dong di » dong sin
man eiu » man ein, iran eiu

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: ((((wing ian) OR (wing tan))) OR (dong di)) ((yang yang) OR (fang yuan)) sang minh kann man eiu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wing ian) or (wing tan))) or (dong di)) ((yang yang) or (fang yuan)) sang minh kann man eiu ;*.
