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

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