Perhaps you should try some spelling variations:
ying thanh » binh thanh, long thanh, ying chang
wang yang » wang yan, wang liang, wang yanling
wan wang » wen wang, yan wang, qian wang
xi irene » _ irene, i rene, ii rene
wie rene » wilke rene, wie deine, wie eine
yang jin » yang jie, yang jun, ying jin
jin ying » li ying

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: wan wang yang ((xi irene) OR (wie rene)) yang jin ying thanh ;~.
• Adding a wildcard symbol may retrieve word variants: wan wang yang ((xi irene) or (wie rene)) yang jin ying thanh ;*.
