Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
hua west » a west, out west
yang lin » yang jin, wang lin, yang li
wang yue » wong yue, wang hua, wang yan
yan tin » yuan ting, yang jin
wang li » wang lei, wang lin, tang li

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