Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
chia wenn » chia wen
wong shiu » wong siu, cong shu, song shin
dong nan » dong yang, dong sin, dong bin
tan chia » tuan china, than china, can china
ein lehr » ein sehr, von lehr
ein lohn » die lohn, den lohn, ein lord

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong nan) or (((yang yang) or (wang yang)))) tan chia wenn ((ein lehr) OR (ein lohn)) wong shiu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (((yang yang) OR (wang yang)))) tan chia wenn ((ein lehr) OR (ein lohn)) wong shiu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (((yang yang) or (wang yang)))) tan chia wenn ((ein lehr) OR (ein lohn)) wong shiu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (((yang yang) or (wang yang)))) tan chia wenn ((ein lehr) OR (ein lohn)) wong shiu ;*.
