Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yuan dinh » tuan minh, yuan lin, yuan ming
tung t'an » tung tran, tung xuan
t'an kong » tan kong, nan kong
wing tan » wing ian, liang tan, hong tan
dong bin » dong sin, dong di, dann bin
yan yuan » yan guan, fang yuan, nan yan
kong eiu » tonga 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: ((((wang yang) OR (wing tan))) OR (dong bin)) yan yuan dinh tung t'an kong eiu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (wing tan))) or (dong bin)) yan yuan dinh tung t'an kong eiu ;*.
