Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
hua west » a west, hua wei, out west
yang lin » yang jin, yang li, yang liang
wang lin » wang li, wang qin, wang limin
yan tin » yuan ting, yang jin
hong yu » wong yue

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: ((yang yang) OR (wang yang)) wang hua west ((yan tin) OR (((yang lin) OR (wang lin)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) OR (wang yang)) wang hua west ((yan tin) or (((yang lin) or (wang lin)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) OR (wang yang)) wang hua west ((yan tin) or (((yang lin) or (wang lin)))) hong yu ;*.
