Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang dan » wang yan, wang ban, wang yidan
six west » six we, six week
die west » die welt, die weiss, die werte
yang nhi » yang chik, yang di, yang jui
wang chi » wang zhi, wang chau, wang chun
hoang sy » hoang vu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (wang dan)) ya ((six west) OR (die west)) ((yang nhi) or (wang chi)) hoang sy ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang dan)) ya ((six west) OR (die west)) ((yang nhi) OR (wang chi)) hoang sy ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang dan)) ya ((six west) OR (die west)) ((yang nhi) or (wang chi)) hoang sy ;*".
