Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
yan wang » yuan wang, qian wang, yan liang
wong yue » wang yue, hong yu
dan yan » dan yang, nan yan, wang yan
hua ren » hua chen
yang li » yang lin, yang di, yang xi

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: dan yan wang hua ren ((((((yang liang) OR (yang yang))) OR (wang yang))) OR (yang li)) wong yue ;~.
• Adding a wildcard symbol may retrieve word variants: dan yan wang hua ren ((((((yang liang) or (yang yang))) or (wang yang))) or (yang li)) wong yue ;*.
