Perhaps you should try some spelling variations:
wang yidan » wang yan
wang yang » wang yan, wang liang, wang yanling
wang chun » tang chun, wong chun, wang hua
six west » die west, six we
six week » six weeks, six we
wang chi » wang zhi, wang chau, yang chik
hoang sy » hoang vu

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 (wang yidan)) a ((six west) OR (six week)) ((wang chi) OR (wang chun)) hoang sy ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yidan)) a ((six west) or (six week)) ((wang chi) OR (wang chun)) hoang sy ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yidan)) a ((six west) or (six week)) ((wang chi) OR (wang chun)) hoang sy ;*.
