Perhaps you should try some spelling variations:
yang wang » yan wang, yang guang, yang liang
yang yang » wang yang, wang yan
hong than » hong tan, long thanh, hong hai
lang yan » wang yan, wang yang, zhang yan
yang jun » yang jui, pang jun, yang jin
jun qian » sun qiang, ji qian, jun jean
chan ha » chang ha, chan h, chan chak
hong ma » hong a, hong tan, hong hai

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: lang yan ((yang wang) OR (yang yang)) yang jun qian ((chan ha) OR (((hong ma) OR (hong than)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yang wang) OR (yang yang)) yang jun qian ((chan ha) or (((hong ma) or (hong than)))) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yang wang) OR (yang yang)) yang jun qian ((chan ha) or (((hong ma) or (hong than)))) ;*.
