Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
yang wang » yang yang, yan wang, yang liang
hua west » a west, hua wei, out west
yan clan » das clan, yan yuan
yan guan » gan guan, yan yuan, yihan guan
yan tan » tan tan, yan wang, yan yuan
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: wang ((yang wang) OR (yang guang)) hua west ((yan tan) OR (((yan clan) OR (yan guan)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang wang) OR (yang guang)) hua west ((yan tan) or (((yan clan) or (yan guan)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang wang) OR (yang guang)) hua west ((yan tan) or (((yan clan) or (yan guan)))) hong yu ;*.
